The QS18VP6LPQ8 is a Miniature Self-contained Photoelectric Sensor in universal housing. Exceptional optical performance, comparable to larger "MINI-style" or barrel sensors. 10 to 30VDC operation, with complementary (SPDT) PNP output. Bright LED operating status indicators are visible from 360°. Rugged sealed housing, protected circuitry. Less than 1 millisecond output response for excellent sensing repeatability.
