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.","metaTitle":"EE-SPZ401-A Photomicro Retro-Reflective Sensor, NPN","metaDescription":"Active production retro-reflective photomicrosensor.
