Azbil Corporation FL7M-3J6HD-L5 Proximity Sensor

Azbil FL7M-3J6HD-L5 is a cylindrical DC 2-wire proximity sensor with a 5-meter pre-wired cable, designed for compact, non-contact detection in industrial automation. The sensor features a 12 mm diameter M12 housing and a 3 mm nominal sensing distance with a normally open output, making it a straightforward drop‑in for small targets in tight spaces. It uses a high-frequency oscillation actuation method and provides a usable sensing range from 0 to 2.1 mm, helping ensure reliable detection within its specified distance. The housing is a nickel-plated brass body with a PBT face for durability in demanding environments, and the unit weighs about 60 g, suited for easy integration into machinery without adding excessive mass. In addition, the FL7M family is built to IP67G protection, guarding against dust and water ingress, and the 5 m cable length simplifies wiring in compact assemblies, reducing panel wiring complexity in single-supply circuits. This DC 2-wire configuration aligns with Azbil’s line of cylindrical proximity switches that emphasize robust sensing performance in harsh industrial settings.
