Banner QH23SN6FP Q23 plastic fiber optic sensor 10-30V dc NPN 2 m cable IP67

Plastic fiber-optic sensor

This Banner QH23SN6FP sensor uses plastic fiber optics to detect objects in diffuse proximity mode. It operates on a 10-30V dc supply and provides complementary NPN output signals through a 2 m cable. The rectangular thermoplastic housing meets IP67 and multiple NEMA ratings for wash-down environments.

Suits automated lines needing discrete presence

The unit is designed for fixed-position detection where a separate fiber assembly guides the visible red LED beam. It lacks remote-teach capability, intrinsic-safety certification and water-detection features, so applications requiring those functions should consider alternative devices.

1 ms response time with 250 µs repeatability

These timing figures define the sensor's ability to resolve fast-moving targets on conveyors or indexing stations. A 100 ms power-up delay and potentiometer adjustment complete the performance envelope for high-speed discrete control tasks.
