Part Number Decoder: What Does BSP B600-EV009-P00S2B-S4 Mean?

Rather than memorising a type code, understanding its structure helps you quickly verify you have the correct variant:

Segment	Meaning
BSP	Balluff pressure sensor family
B600	Measuring range: 0–600 bar (relative)
EV009	Electronic version / sensor cell variant
P00	Process connection: G 1/4" (DIN 3852), stainless steel
S2B	Output configuration: IO-Link + 2× switching + analog
S4	Connection: M12 × 1, 4-pin

If you need a different pressure range but the same output and connection configuration, simply change the range segment — for example, BSP00Y4 covers 0–10 bar with the identical interface.

Three Output Modes in One Device

One of the BSP00YK's most practical features is its output flexibility. A single sensor covers three different signal architectures:

① Analog Output — 4…20 mA or 0…10 V The analog output provides a continuously proportional signal across the 0–600 bar range. The 4…20 mA current loop variant is preferred for long cable runs (immune to resistive voltage drop) and for process control systems with 4…20 mA analog input cards. The 0…10 V option suits PLC analog inputs with voltage-type inputs. The selection is made via IO-Link parametrisation or local button configuration.

② Two Switching Outputs (PNP / NPN, NO / NC) Two independent transistor switching outputs allow the sensor to trigger two separate threshold events — for example, a low-pressure warning at 50 bar and a high-pressure trip at 550 bar. Each output can be independently configured as PNP or NPN and as normally open or normally closed, allowing integration with either sourcing or sinking PLC input modules without additional signal conversion hardware.

③ IO-Link 1.1 Digital Communication IO-Link provides full bidirectional digital communication between the sensor and an IO-Link master. Over IO-Link, the sensor transmits the measured pressure value as a 16-bit digital word (eliminating analog conversion error), and the controller can remotely read diagnostics, change switching thresholds, adjust output configuration, and write parameter sets — all without physical access to the sensor. This is particularly valuable in installations where the sensor is mounted in an inaccessible location or where rapid changeover between product recipes requires repraming of pressure thresholds.

Where Is the BSP00YK Deployed?

Hydraulic Power Units & Press Lines With a 600 bar range and 1,000 bar overload rating, this sensor is built for high-pressure hydraulic circuits on metal-forming presses, injection moulding machines, and forging equipment. The FKM gasket and stainless steel process connection handle hydraulic oil and water-glycol fluids.

High-Pressure Water Systems Waterjet cutting systems, industrial cleaning equipment, and high-pressure water injection systems often operate in the 200–600 bar range — exactly where this sensor's range is optimised.

Plastic Injection Moulding Mould cavity pressure monitoring and hydraulic clamp pressure monitoring on injection moulding machines, where precise pressure control directly impacts part quality and cycle consistency.

Leak Testing Equipment Pressure decay testing of components and assemblies at elevated pressures, where stable, accurate readings and switchable alarm outputs are essential.

Industrial Automation with IO-Link Networks Any application where IO-Link architecture is used for distributed sensor parametrisation, predictive maintenance data collection, or centralised condition monitoring — the BSP00YK integrates directly into any IO-Link 1.1 master port.

The Rotatable Display — A Practical Detail That Matters

The M12 connection is independently rotatable lautomation, and the LED display housing can be rotated up to 330° relative to the process connection — meaning once the sensor is screwed into the hydraulic port, the display can be oriented to face the operator regardless of the installation angle. On a press line where sensors are mounted at 45° angles inside the machine frame, this eliminates the need for mirror reading or contorted viewing angles. The display shows the current pressure value in the configured engineering unit and also indicates the switching output status.

BSP00YK vs Comparable Balluff Pressure Sensor Variants

Model	Range	Key Difference
BSP00YK	0–600 bar	High-range hydraulic/process applications
BSP00Y4	0–10 bar	Low-pressure pneumatic/fluid systems
BSP00YR	−1…+2 bar	Vacuum and low positive pressure
BSP00JK	0–10 bar	No display, compact, analog-only output
BSP000R	0–600 bar	Predecessor — BSP00YK is the direct replacement

Important: If you are currently running BSP000R sensors and need replacements, the BSP00YK is the official Balluff successor and is a direct functional replacement with enhanced IO-Link 1.1 capability.

OEM vs Generic Pressure Sensors — The Case for Balluff

High-pressure sensors are not a component category where generic substitution is advisable. At 600 bar system pressure, a seal failure or housing fracture is a safety incident, not an inconvenience.

Frequently Asked Questions

Q1: What does BSP00YK measure — absolute or relative (gauge) pressure? The BSP00YK measures relative (gauge) pressure, meaning it measures pressure relative to ambient atmospheric pressure. At atmospheric pressure, the output reads zero. Absolute pressure sensors measure relative to a perfect vacuum (zero reference). For most industrial hydraulic and pneumatic applications, gauge pressure is the correct measurement — it tells you the actual working pressure above atmospheric, which is the value that drives system behaviour.

Q2: What is the difference between ±0.5% FSO BFSL accuracy and other accuracy specifications? FSO means Full Scale Output — the accuracy figure applies across the entire 0–600 bar range. BFSL means Best Fit Straight Line — the error is calculated after fitting the ideal straight line through the measured data, which removes offset and gain error and represents only the nonlinearity component. This is a favourable but standard method of specifying sensor accuracy in the industrial sensor industry. The practical implication: at 600 bar full scale, ±0.5% FSO equals ±3 bar of maximum error across the range.

Q3: What is IO-Link 1.1, and does my system need to support it? IO-Link is a point-to-point serial communication standard (IEC 61131-9) for sensors and actuators. The sensor connects to an IO-Link master module (available from Balluff, Siemens, Turck, Pepperl+Fuchs, and others) which is typically installed in a PLC IO rack or field-mounted junction box. If your system does not have an IO-Link master, the BSP00YK can still be used in standard I/O mode — the switching outputs and analog output function normally without IO-Link communication. IO-Link adds remote parametrisation and diagnostics on top of the standard signal outputs; it does not replace them.

Q4: Can the switching thresholds be set without IO-Link — using the buttons on the sensor? Yes. The BSP00YK has local push-button configuration accessible via the sensor's front panel. Switching point thresholds (SP1, SP2), hysteresis, output polarity (NO/NC), and analog output type (4–20 mA or 0–10 V) can all be set locally without an IO-Link master or configuration tool. Parametrisation follows the VDMA standard interface, which is consistent across Balluff's BSP series and familiar to engineers working with other VDMA-compliant pressure sensors.

Q5: What fluids is the BSP00YK compatible with? The wetted materials are 1.4301 (304) stainless steel for the process connection and FKM (Fluoroelastomer / Viton) for the gasket. This combination is compatible with mineral hydraulic oil, water-glycol hydraulic fluid, synthetic esters, clean water, mild acids, and many industrial process fluids. It is not suitable for strongly oxidising acids, concentrated alkalis, or fluids that attack stainless steel or FKM. For aggressive media applications, consult Balluff's chemical compatibility data before specifying.

Q6: What is the difference between the BSP00YK and its predecessor BSP000R? The BSP00YK replaces the BSP000R lautomation as the current active catalogue part. The BSP00YK adds IO-Link 1.1 communication capability (the BSP000R had IO-Link 1.0 or no IO-Link depending on variant), updated electronics with the EV009 generation sensor cell, and the independently rotatable M12 connector. Mechanically and electrically, the BSP00YK is a drop-in replacement for the BSP000R — same G1/4" process connection, same M12 connector, same output signal types.

Q7: What does the overload pressure of 1,000 bar mean in practice? Overload pressure is the maximum pressure the sensor can withstand — including pressure spikes — without permanent damage to the measuring cell or loss of calibration accuracy. The BSP00YK will survive pressure peaks up to 1,000 bar without recalibration being required. The burst pressure of 1,570 bar is the pressure at which the housing may fail mechanically — this is a safety margin figure, not an operating limit. For systems with known pressure spikes (e.g., hydraulic hammer from valve closure), the 1,000 bar overload rating provides a 1.67× safety factor over the 600 bar measuring range.

Q8: The sensor is rated IP67. Can it be submerged in fluid during operation? IP67 means the sensor is protected against temporary immersion in water up to 1 metre depth for 30 minutes. For standard industrial environments — splashing, spray, washdown — IP67 provides robust protection when the M12 connector is fully mated and tightened. Note that the IP67 rating applies when the sensor is threaded into the process connection and the M12 connector is connected. An unmated sensor with an open M12 socket is not rated IP67 at the connector entry.

Q9: What cable or connector do I need to connect the BSP00YK? The sensor has an M12 × 1, 4-pin male connector on the sensor body. You need a mating M12 female, 4-pin straight or angled cable assembly. Standard pin assignment: Pin 1 = +V supply (brown), Pin 3 = 0V / GND (blue), Pin 4 = Output 1 / IO-Link C/Q (black), Pin 2 = Output 2 (white). Balluff and many third-party suppliers offer pre-assembled M12 cables in various lengths. For IO-Link operation, use an unshielded 3-wire or 4-wire cable per the IO-Link standard; maximum cable length per IO-Link port is 20 metres.

Q10: Is this sensor suitable for food and beverage or pharmaceutical applications? The BSP00YK with G1/4" stainless steel connection and FKM gasket is used in many industrial food processing applications — it is not a hygienic design sensor (no Tri-Clamp or EHEDG/FDA-compliant wetted materials are specified for this variant). For food-contact or pharmaceutical applications requiring hygienic process connections and FDA-approved materials, Balluff offers specific hygienic variants within the BSP series. The BSP00YK is appropriate for non-product-contact measurement points such as hydraulic circuits, cooling water, and utility systems in food factories.
