Retro-reflex sensor with 6500 mm range

The Wenglor LM89PA2 is a retro-reflex photoelectric sensor designed for presence detection in industrial automation. It operates on a 10...30 V DC supply and provides a PNP antivalent output with 200 mA switching current. The red-light source includes a polarisation filter and two-lens optic for reliable detection up to 6500 mm.

Suited for DC control systems needing antivalent

This sensor suits installations that require both normally-open and normally-closed signals from a single device. It is not for applications that need an NPN output type or an IO-Link communication interface. Buyers who need a diffuse or through-beam sensing principle should look at a different product.

6500 mm sensing range with RQ100BA reflector

The maximum operating distance is 6500 mm when used with the specified RQ100BA reference reflector. Range will be reduced with smaller reflectors or reflector foils. Verify the mounting distance and reflector size against this figure before purchasing.

Questions about this item

What supply voltage must my control cabinet provide for the LM89PA2 to operate?

The sensor runs on 10...30 V DC, so any regulated DC source in that range will power it.

Will the LM89PA2 still detect the RQ100BA reflector if ambient light reaches 10000 Lux in my plant?

Yes, the spec lists a maximum ambient light of 10000 Lux, so detection remains reliable up to that level.

After wiring the M12 connector, how can I verify the sensor is switching correctly?

Turn the potentiometer until the output toggles when the beam hits the reflector; the 1 kHz switching frequency gives a clear on/off signal you can monitor with a multimeter or PLC input.
