Pull 10–30 VDC to the 2 m cable, and it switches 100 mA loads at 1 ms response. Light-ON / Dark-ON selectable covers both presence and absence detection from the same unit. IP64 keeps dust and splashes out; fine for indoor conveyor lines or covered outdoor gates, but skip the washdown zone — that’s where you’d want the IP69K from the smaller E3ZM series. ## How it stacks against the compact E3ZMB812MOMS For a panel already drilled for the E3ZM’s M8 threaded barrel, the E3JK’s through-hole mounting (18 mm wide block) won’t align. Rewiring is straightforward — both are PNP, 10–30 V, 100 mA — but you’ll need to redrill or adapt the bracket. Where range matters — pallet detection, long conveyor gaps — the E3JK’s 10 m is the clear pick. The E3ZM’s 500 mm is for short-reach retro-reflective on small parts. ## Sourcing reality for the E3JK series No official successor published in the Omron line, so this is a straight replace-when-broken part for existing panels. The value for a liquidation buyer: high likelihood of being spec’ed into older machinery, easy to move as a known SKU. ## Wiring and swap notes Three-wire PNP — brown to +10–30V, blue to 0V, black as switched output. The 2 m cable is pre-wired, no connector to fuss with. Response time 1 ms is fast enough for most counting and positioning; if you need sub-millisecond, look at the fiber-optic amplifier series. Mounting: two through-holes for M3 or M4 screws, centers approximately 50 mm apart (check the full dimension datasheet for exact hole pattern). IP64 means no conduit seal required indoors, but keep the cable entry pointed down to avoid water tracking.","metaTitle":"Omron E3JKRP122MOMI PNP Retro-Reflective Sensor, 10m","metaDescription":"Omron E3JKRP122MOMI retro-reflective photoelectric sensor.
