Baumer IFRM 08X9503 Inductive Proximity Sensor NAMUR

Baumer IFRM 08X9503 NAMUR inductive proximity sensor is an 8 mm flush-mount device designed for Ex i NAMUR circuits in hazardous environments, delivering non-contact detection with a nominal sensing distance Sn of 1.5 mm. This two-wire NAMUR sensor uses a 5–30 VDC supply (normal operating voltage 8.2 VDC) and draws >4 mA undamped (≤10 mA no-load; damped <1 mA); it has Ui < 13.5 VDC, Ii < 37 mA, Pi < 0.125 W, and NAMUR output. The housing is brass nickel-plated with a PBT sensing face, measuring 8 mm in diameter and 25 mm in length, and is supplied with a 2 m cable. The unit is IP67 rated and supports a wide operating ambient range from -25 to +75 C; its safety certifications include SEV 21 ATEX 0551 X and IECEx SEV 21.0019X, with markings II 1G Ex ia IIC T6 Ga (and related temperature classes). This model is part of Baumer’s Ex i NAMUR line, specifically configured for robust inline detection in hazardous zones, where the 1.5 mm nominal sensing distance and rugged construction enable reliable sensing through non-magnetic environments while maintaining strict explosion‑protection compliance.
