Decoding the designation

SPAU — Festo’s electronic pressure sensor family for compressed air and inert gases.

P10R — relative pressure, measuring range 0 to 10 bar.

MS4 — flange pneumatic connection sized for the MS4 series air preparation unit.

F — front panel mounting provision, 34 x 61 mm cut-out.

L — illuminated LCD display with three-button operation.

PNLK — output A: a switching output selectable as PNP or NPN, carrying IO-Link communication on the same pin.

PNVBA — output B: selectable as a second PNP or NPN switching output, or as an analogue voltage or current output.

M12D — M12x1 plug, four pins, A-coded.

What these specs mean in practice

Accuracy: ±1.5 % FS at room temperature. Repetition Accuracy: ±0.3 % FS. Temperature Coefficient: ±0.05 % FS/K. ADC Resolution: 12 bit. Rise Time: 3 ms. A 12-bit conversion over a 10 bar span resolves to roughly 2.5 mbar, which is why the same sensor covers coarse supply-pressure monitoring and fine leak-rate work.

Operating Voltage: 20 to 30 V DC. Idle Current: typically 35 mA. Maximum Output Current: 100 mA per switching output. Voltage Drop: max 1.6 V. Short-Circuit Protection: yes. Reverse Polarity Protection: on all electrical connections. Ready-State Delay: typically 160 ms.

Analogue Output Options: 0 to 10 V, 1 to 5 V, or 4 to 20 mA. Maximum Load Resistance, Current Output: 500 ohm. Minimum Load Resistance, Voltage Output: 10 kilohm.

Switching Element Function: normally open or normally closed, switchable. Switching Function: freely programmable across three modes — threshold value comparator for a single set point, window comparator for a pressure band, and automatic difference monitoring, which learns a reference pressure and switches when the line drifts outside a set band. That third mode is what turns the sensor into a leak detector on a clamped or sealed volume.

Threshold Value Setting Range: 0 to 100 % FS. Hysteresis Setting Range: 0 to 90 % FS. Displayable Units: bar, kPa, MPa, psi, mmHg, inchHg, inchH2O, kgf/cm².

IO-Link Protocol Version: Device V1.1. Profile: Smart Sensor. Communication Mode: COM2, 38.4 kBd. Port Class: A. Process Data Width In: 2 byte, carrying a 14-bit pressure value and a 2-bit monitoring flag. Minimum Cycle Time: 3 ms. SIO mode is supported, so the same sensor runs as a plain switching sensor on an ordinary digital input.

Certification: UL and cUL listed, file E322346, to UL 61010-1 and CAN/CSA C22.2 No. 61010-1. RCM compliance mark. CE marking to the EU EMC and RoHS directives.

Operating limits and media

Operating Medium: compressed air to ISO 8573-1:2010 [7:4:4], and inert gases. Operation with oil lubrication is possible. Temperature of Medium: 0 to 50 °C. Ambient Temperature: 0 to 50 °C. Storage Temperature: −20 to +80 °C. Corrosion Resistance Class: CRC 2, moderate corrosion stress.

Shock Resistance: 30 g acceleration at 11 ms half-sine to EN 60068-2. Vibration Resistance: 0.35 mm amplitude from 10 to 60 Hz, 5 g from 60 to 150 Hz.

Mounting data

Type of Mounting: on a service unit. Mounting Position: any. Front Panel Cut-Out: 34 x 61 mm. Maximum Tightening Torque, service-unit mounting: 1 Nm. Maximum Tightening Torque, M12 plug: 0.5 Nm. Maximum Tightening Torque, front panel screws: 0.7 Nm, M3. Maximum Cable Length: 30 m, or 20 m in IO-Link mode.

Quantity and configuration

Unit Quantity: 1 Pc. Sensor only.

Interchange guidance

SPAU-P10R-MS6-F-L-PNLK-PNVBA-M12D is the identical sensor on the larger MS6 service-unit flange. SPAU-P10R-W-Q6D-L-PNLK-PNVBA-M12U carries the same electronics with wall mounting and a QS push-in fitting, so it suits a free-standing line rather than a service unit. Measuring-range variants on the same body run P025, P05, P1, P2, P6, P12 and P16 for pressure and V025, V05, V1, B2 and B11 for vacuum and combined ranges — the range code is the only difference, so a P6 body will not read above 6 bar and a P16 body gives coarser resolution over the same 10 bar span.
