Baumer IFRM 08X9503 Inductive Proximity Switch

Baumer IFRM 08X9503 is a compact NAMUR inductive proximity switch designed for hazardous environments, delivering a 1.5 mm nominal sensing distance in a flush-mount cylindrical housing with an 8 mm diameter and 25 mm length. The device uses a brass, nickel‑plated housing with a PBT sensing face and comes with a 2 m shielded cable for reliable field connections. It operates from a DC supply of 5–30 V, with a nominal operating voltage of 8.2 VDC, and features a two‑wire NAMUR output suitable for intrinsically safe signaling. Certified for explosion‑hazard areas, it carries ATEX II 1G Ex ia IIC T6 Ga (and related temperature-class variants) and IECEx SEV approvals, with IP67 protection for dust and water ingress resistance. Electrical characteristics include undamped current consumption above 4 mA, a maximum current of around 37 mA, and a power dissipation under 0.125 W, with residual ripple under 10% of Vs. Temperature and operating limits reflect its NAMUR, Ex i design: the temperature class ranges from -20 to +60 °C (T5) and -20 to +40 °C (T6), while ambient operating conditions span -25 to +75 °C. The IFRM 08X9503 is suited for simple, NAMUR-compatible sensing in automation and safety-critical applications where compact size, robust ingress protection, and certified hazardous‑area operation are essential.
