The rectangular plastic body has an IP67 rating and selectable Light-On/Dark-On operation. ## Direct Functional Peer The alternate MPN E3K-R10K4 is nearly identical — same 10 m retroreflective range, same relay output, same IP67 rectangular body — but its supply voltage range starts at 42 VAC instead of 24 VAC. If your panel already runs 24 VAC or DC, stick with the E3KR10K4; if you can live with the higher AC minimum, the E3K-R10K4 is a drop-in alternative for BOM flexibility. Terminal block connection, 30 ms response time, and a built-in indicator simplify commissioning. The right-angle sensor face and 64 mm diameter head fit standard retroreflective brackets.","metaTitle":"Omron E3KR10K4 Photoelectric Sensor, Retroreflective, 10m, I","metaDescription":"Omron E3KR10K4 industrial photoelectric sensor with 10 m retroreflective range, IP67, DPDT relay output, 24-240V AC/DC – active production, ships fast.
