What this sensor is and where it fits
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.
Key ratings and what they mean for fit
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.
