What This Sensor Does and Where It Fits
The E3JKRR125MOMS is a retro-reflective photoelectric sensor with a relay output rated for 100 mA at 24–240 V AC/DC. The relay allows direct switching of higher-voltage loads without an interface module, though the 20 ms response time limits it to applications where object speed is not critical — think conveyor presence detection or level sensing in slower material handling. Cable-connected with 5 m of wire, rated IP64 for splash-resistant indoor environments. The 10 m sensing range provides headroom for dusty or slightly misaligned retro-reflectors, but the minimum distance of 100 mm means you cannot detect objects closer than that.
How It Compares to the E3SDBP21TOMS
If your panel uses 24 VDC only and needs fast sensing, the E3SDBP21TOMS is the closer fit — but expect to change the connector and cable length. If you need relay isolation for AC loads, the E3JK is the correct choice.
