Inductive sensor 237-7255, M18, flush, Sn=8mm, PNP/NPN, NO/NC, IO-Link, 2 m PVC cable, IP67

237-7255 is an RS PRO M18 inductive sensor with IO-Link V1.1, the long-housing flush version with an 8 mm sensing distance and a 2 m cable. Output type, NO or NC function and sensing distance are set over IO-Link; without a master it works as a standard PNP NO switch.

• Sensing distance: 8 mm, flush mounting; settable over IO-Link to 33, 50, 75 or 100 % (factory 100 %), hysteresis standard or increased
• Output: PNP, NPN or push-pull, NO or NC (factory setting PNP NO); up to 200 mA, voltage drop max. 2.5 V at 200 mA; switching frequency up to 1.5 kHz; IO-Link V1.1
• Supply: 10...36 VDC, 3-wire, no-load current ≤ 20 mA
• Protection: short circuit, reverse polarity, transients
• Housing: M18x1, nickel-plated brass, grey thermoplastic polyester front cap, tightening torque max. 25 Nm
• Environment: IP67, operating temperature -25...+70 °C
• Connection: 2 m PVC cable, 3 x 0.25 mm², Ø 4.1 mm, oil-resistant

The yellow LED shows the output state and flashes at 2 Hz on short circuit or overload; the green LED shows that the sensor is operational. A temperature alarm can be enabled over IO-Link, and both LEDs can be switched off.

Designed to EN 60947-5-2 and EN 60947-1; UL 508 approval. Vibration per IEC 60068-2-6 (10...55 Hz, 1 mm), shock per IEC 60068-2-27 (30 g, 11 ms). MTTFd 3945 years at 50 °C.
