The E2E-S05N03-WC-B1 2M: This M5 threaded barrel proximity sensor fills a niche for compact target detection where a 5 mm diameter threaded housing fits into tight metalwork. Unshielded, it gives a 3 mm sensing range on ferrous targets — about double what a shielded M5 would manage. The PNP normally open output and 2 m PVC cable mean it wires directly into a 3-wire DC input card without a connector.
Peer comparison — E2C-X1R5AH
The heat-resistant sensor head E2C-X1R5AH is a shielded M8 unit with 1.5 mm range, intended for high-temp environments up to 200 °C. That part uses a separate amplifier; this E2E is a self-contained DC switch. If your panel was dimensioned for an M8 mounting hole, this M5 sensor will not drop in without an adapter. The sensing range difference (1.5 vs 3 mm) also changes position detection logic.
The unshielded coil allows for a wider detection zone but may require a non-metallic surround for flush mounting. In a metal panel, maintain a gap of at least the sensing distance from surrounding steel. The IP67 rating covers coolant splash and washdown, making it suitable for machine tool jigs and assembly stations.
