Retro-reflex sensor with 5,5 m range

The Wenglor LN89PDV3 is a retro-reflex photoelectric sensor that detects objects up to 5 500 mm using the RQ100BA reflector. It operates on 10...30 V DC and provides a PNP normally-closed switching output rated at 200 mA. The red-light emitter includes a polarisation filter and a 5 ° opening angle for precise detection.

Industrial automation and conveyor applications

This sensor suits production lines, packaging machines and material-handling systems that require reliable presence detection at medium range. Buyers who need a through-beam or diffuse-mode sensor, or who require an NPN output type, should look at a different product.

IP67-rated plastic housing with M12 connector

The fully encapsulated plastic housing meets IP67 and withstands -10...60 °C ambient temperature. A 4-pin M12 × 1 connector simplifies wiring, while built-in short-circuit, reverse-polarity and overload protection increase uptime. A potentiometer allows quick sensitivity adjustment on site.

Questions about this item

What size M12 connector and cable do I need to wire the LN89PDV3 sensor?

The sensor uses an M12 × 1 4-pin connector; choose a matching 4-pin M12 cable rated for 10...30 V DC and the 200 mA switching current.

Which potentiometer sets the switching distance and how many turns does it take?

The single potentiometer on the housing adjusts the sensing range up to 5500 mm; turn it slowly while watching the output LED until the target at the desired distance triggers reliably.

How often should I clean the lens and when is the red light source expected to reach its 100000 h service life?

Wipe the plastic lens with a soft dry cloth whenever dust builds up; the red LED is rated for 100000 hours at 25 °C, so plan replacement after roughly that operating time.
