Overview
The XU9M18MB230W is a Schneider XU9 series polarized retroreflective photoelectric sensor in an 18 mm nickel plated brass barrel, rated for a 2 m sensing distance and a 200 mA load current. It operates on a 24 to 240 VAC/VDC supply with a normally-closed (NC) output, making it a direct choice for fail-safe or alarm circuits where loss of beam must signal a fault. Sealed to IP67 and NEMA 4X/12, the sensor is prewired with a 2 m PVR cable and carries UL, CSA, and CE approvals.
How it compares
Compared to the XU9M18MA230K, the XU9M18MB230W uses a fixed 2 m sensing distance versus the 3 m range of the MA230K, and its NC output suits fail-safe wiring, whereas the MA230K provides a solid state transistor output. The XU9M18MB230W also differs in connection: a 2 m PVR cable versus the 1/2 inch-20 UNF connector on the MA230K, so panel wiring changes are needed when swapping between the two.
Lifecycle and sourcing
The XU9M18MB230W is an active catalog item from Schneider; availability is steady through distribution, and an RFQ confirms current lead time and pricing for the exact build.
