The E3F2DS10C4N is a fixed-sensitivity diffuse reflective photoelectric sensor in an M18 plastic barrel with PMMA lens. The 880 nm infrared LED provides a 100 mm sensing distance on a standard white target. NPN output is selectable for Light-ON or Dark-ON via wiring, common for PLC inputs. Response time is 2.5 ms, adequate for moderate-speed object detection.
Barrel diameter 18 mm, length 64.9 mm — mounts through a standard 18 mm hole with two locknuts (not included). No sensitivity adjustment is provided; sensing distance is factory-set. Pre-wired cable exit (cable length to be confirmed on the actual unit). Connect brown to +10-30 VDC, blue to 0 V, black to NPN load. Light/Dark-ON selection typically by connecting the load to different pins or using a selector — verify with the specific unit's wiring diagram.
