The Omron E3ZG82M3JOMS is a through-beam photoelectric sensor from the E3Z family, rated 25 mm sensing distance with a 1 ms response time, PNP output, and an M8 4-pin connector for quick field swaps. At 11 mm wide, it fits narrow DIN slots and offers IP64 protection for dusty or splashy environments. The 100 mA output drives PLC inputs directly.
Connector versus cable – the real difference
The E3ZG82M3JOMS uses an M8 4-pin connector, unlike the E3ZG812MOMS with a 2 m cable. If your panel uses pre-terminated pigtails or you need to swap sensors without pulling new wire, the connector version saves downtime. Output is PNP, matching the E3ZG81M3JOMS; for NPN systems, the E3ZG61M3JOMS is the drop-in electrical alternative with the same 11×40×50 mm body and M8 connector.
Panel fit and environmental limits
The 11 mm width and 40×50 mm footprint clear most DIN-rail layouts. Operating temperature spans -25 to 55 °C. IP64 rating handles hose-down but not immersion. Mounting brackets are standard for the E3Z series.
