The Omron E2B-S08KS02-WP-C1 2M is an inductive proximity sensor from the E2B series. It is shielded (flush-mountable) and has a 2 mm sensing distance (0.079 in).
2 mm sensing range — what it means for mounting
The 2 mm nominal sensing distance is the maximum rated range for a standard steel target. Because the sensor is shielded, you can flush-mount it in metal without derating the sensing distance — a common requirement when retrofitting into existing tapped holes or brackets. For non-ferrous metals (aluminum, brass), expect the effective range to drop to roughly half the steel value. The switching frequency of 1500 Hz keeps up with moderate-speed counting or position feedback on indexing tables.
Output and wiring — NPN-NO, 3-wire
This sensor outputs an NPN normally-open signal on a 3-wire cable. The output transistor sinks current to ground when a target is present.
