Application fit

The Wenglor HB03PBT7K is a PNP reflex sensor designed for presence detection at distances between 10 and 30 mm. It suits automation engineers who need a compact stainless-steel housing with IP67 protection and a 20 cm M8 pigtail for direct connection to PLC inputs.

Interface limits

The sensor operates on 10...30 V DC and draws less than 25 mA at 24 V. Its PNP normally-open output switches up to 100 mA with a voltage drop below 2,5 V. Built-in short-circuit, reverse-polarity and overload protection guards the output stage, while the 600 Hz switching frequency and 833 µs response time set the maximum detectable event rate.

Capacity and headroom

The red-light spot measures 2 mm at the sensing face and the adjustable range tops out at 30 mm, so targets must enter this narrow zone. Ambient light immunity reaches 10000 Lux and temperature drift stays under 5 % across -25...60 °C. Rated service life is 100000 hours at 25 °C; applications requiring longer range, faster switching or higher output current will exceed the device limits.

Questions about this item

Should I use the full 30 mm range or keep it closer to 10 mm?

The sensor adjusts from 10 to 30 mm; teach-in lets you set the exact switching point for your target distance.

What does the 600 Hz switching frequency mean on the production line?

It allows up to 600 detection cycles per second with an 833 µs response time, suitable for fast-moving parts.

How does the M8 4-pin connector limit the cable run?

The sensor includes a 20 cm pigtail with an M8 × 1 4-pin plug; extend with a compatible M8 cable for longer runs.
