The E3G A-119 photoelectric switch with built-in amplifier (long distance) in plastic housing has a sensing distance of 10 m, with polarized light to detect shiny objects. Operation stability is monitored by the stability indicator. Distance-setting models with a long 2 m sensing distance incorporate a teaching function. The set sensing area (zone setting) function allows detection of shiny objects with uneven surface. This product meets IEC IP67 requirements. It has a M12 rotary connector, pre-wired or terminal block connection.
This manual covers the features, installation, and operation of Omron's E3G series photoelectric switches with built‑in amplifiers. It describes retroreflective and distance‑setting models, their sensing distances up to 10 m, and the various output options such as NPN/PNP selector and relay contacts.
Detailed technical data are provided, including power supply ranges, IP67 protection, response times, and environmental limits. Ordering information, accessory options, and wiring diagrams are also included to aid integration into industrial automation systems.
