Industrial PNP sensor 70...500 mm
The Wenglor HN55PA3 is a red-light photoelectric sensor with a PNP antivalent output for presence detection up to 500 mm. It suits automation engineers who need a single-box solution for conveyor, packaging or material-handling lines. The adjustable range and potentiometer setting allow quick commissioning without software tools. Protection class III and IP67 housing make it viable for wash-down environments.
Check supply voltage and mounting clearance
Verify that your control cabinet provides 10...30 V DC and can supply at least 30 mA at 24 V for the sensor. Ensure the M12 × 1 four-pin connector matches your existing cable harness or plan for a suitable cordset. Confirm the 70...500 mm sensing window fits the target distance and that ambient light stays below 10000 Lux. The 1 kHz switching frequency and 500 µs response time must align with your PLC scan cycle.
Plastic housing IP67 and M12 connector
The red plastic body resists dust and temporary immersion, supporting daily wash-down cycles on food or pharmaceutical lines. An M12 four-pin plug enables fast replacement without rewiring the trunk cable. Short-circuit, reverse-polarity and overload protection reduce downtime from wiring faults. The potentiometer on the housing allows range tweaks while the line runs. A service life of 100000 h at 25 °C and TTFd of 243764 a per EN ISO 13849-1 support long-term safety planning.

Questions about this item
What comes in the box and does the sensor need a separate M12 cable?
The sensor is supplied as a single unit in a box. An M12 × 1, 4-pin cable is required for connection and is not included.
How do I choose the right sensing distance for my application?
The sensing range is adjustable from 70 to 500 mm via a potentiometer; set it to the distance your target will be at.
What does the 1 kHz switching frequency mean on a production line?
The sensor can change state up to 1 000 times per second with a 500 µs response time, suitable for fast object detection.
