The EE-SPZ401-A is a standard-body retro-reflective photomicrosensor with a built-in GaAs infrared LED light source. Output is NPN dark-ON, so the signal line goes low when the reflected beam is interrupted. Supply voltage spans 5 to 24 VDC, letting it run on common 5 V logic rails or 24 V machine control voltage without a regulator. Maximum sensing distance is 150 mm to a standard reflector, which fits most small-parts detection in feeders or packaging machines. Connection is via wireable connectors (not pigtail), so you can pre-wire a harness or replace the sensor without stripping the cable at the unit.

Frequently asked questions
Will the EE-SPZ401-A drop into a panel specified for the E2KC25MF2 without rewiring?
No. The E2KC25MF2 is a capacitive sensor with PNP output, while the EE-SPZ401-A is a retro-reflective photomicrosensor with NPN dark-ON output. They serve different sensing tasks and are not electrically interchangeable.
What are the key electrical ratings of the EE-SPZ401-A?
Supply voltage is 5 to 24 VDC, output is NPN dark-ON, and maximum sensing distance is 150 mm to a retro-reflector.
