Rated 30-200 mm sensing distance, 1 ms response, IP67, and CE marked. Pulse synchronization feature lets you lock the emitter to an external trigger – useful when multiple sensors share a line and you need to avoid cross-talk. Supply is 12-24V DC, load current up to 50 mA. Prewired 2-meter cable with bare ends, right-angle face orientation. Dimensions: 7 mm wide, 25 mm tall, body diameter 11 mm – small enough for tight machine frames. Mounts into the standard 7 mm-wide rectangular cutout or bracket. Right-angle face – emitter and receiver point forward, cable exits the bottom. IP67 means washdown-capable; the PBT body handles mild chemical exposure. Minimum detectable object is 27 mm diameter opaque – not for fine parts.","metaTitle":"Omron E3T-SR22 2M Photoelectric Sensor, Retroreflective NPN","metaDescription":"Omron E3T-SR22 2M retroreflective sensor, NPN dark-on, 12-24V DC, 200 mm range, IP67, CE.
