The Omron E2EC04S12CJB103MOMS is a cylindrical inductive proximity sensor from the E2E series, built in a 4 mm diameter flush-mount body. It detects ferrous targets at a rated distance of 1.2 mm and switches at 4 kHz, making it suited for high-speed position sensing on small moving parts — think cam lobes, actuator positions, or spindle indexing in compact machine stations.
The 1.2 mm sensing distance is the rated operating distance (Sn) for a standard mild-steel target. In flush-mount configuration, the sensor face is level with the mounting surface. Output is PNP normally-open (make contact), sourcing 100 mA max at 10–30 VDC. The 10 mA current consumption is the sensor's own draw; the 100 mA load current is what the output can sink into a PLC input or relay coil. IP67 means the stainless-steel housing and cable entry withstand washdown and coolant splash — fine for machine-tool or packaging-line environments.
