The E3C-LDA51 2M is an active-production laser sensor from Omron with a separate digital amplifier, listed as Laser Sensor with Separate Digital Amplifiers. It outputs PNP, runs on 12 to 24 VDC, and comes pre-wired with a 2 m cable. The slim rectangular plastic amplifier body is sized for tight panel layouts.
Selection notes
The sensor supports L-ON/D-ON operation selectable via the amplifier, so you can set it for light-on or dark-on sensing without moving wiring. External inputs are available for remote control – useful for timing resets or changing sensitivity from a PLC. Rated supply from 12 to 24 VDC gives headroom for typical 24 V industrial control systems; it will run on 24 V panels without extra regulation.
