The Omron E2E-S04N02-WC-B1 2M is a 4mm diameter threaded cylindrical proximity switch from the E2E Small Diameter series, delivering a 2mm sensing distance with an unshielded, normally open PNP output. Its compact form fits where space is tight — think small parts detection, end-of-travel sensing on miniature linear guides, or cam detection in pick-and-place stations. Output is a DC 3-wire PNP open-collector, normally open — standard for sourcing signals to PLC inputs that expect a positive logic level. The 2m PVC cable gives enough reach for local connections without a junction box.
How it compares to E2C-X1R5AH
Against the Omron E2C-X1R5AH: that part is a shielded heat-resistance sensor head (M8 thread) that requires a separate amplifier unit (E2C-AM4A or E2C-AK4A), while the E2E-S04N02-WC-B1 2M is a self-contained 4mm unshielded switched output sensor. The E2C system handles higher ambient temperatures (up to 200°C) and offers a different mounting thread size—M8 vs. 4mm. A panel wired for one will not accept the other without changing the mounting hole and wiring scheme entirely.
