The EE-SPX406-W2A is a slot-type photomicrosensor (through-beam) with the emitter and receiver integrated into a single plastic housing. Sensing distance is max 3.6 mm, so it is meant for detecting the presence of an object passing through the slot — an edge of a moving web, a part in a feeder track, or a flag on a linear actuator. Output is NPN, normally open, Light-ON operation (output on when light path is blocked). Supply voltage 5 to 24 VDC, pre-wired with a cable. The short slot gap defines the application: confined area, close-range detection only.
