Polarized Retroreflective Sensing

This 18 mm photoelectric sensor uses polarized retroreflective sensing with a visible red LED at 630 nm to detect objects up to 3.5 m away. It operates on a wide 20-140 V ac/dc supply and provides a P-MOSFET sourcing output with an 8.3 ms response time. The rectangular ABS housing carries an M18 mounting thread and a fixed 2 m cable.

Indoor and Protected Outdoor Use

The IP67 and NEMA 6 ratings suit dusty or wet environments between -25 °C and 70 °C with up to 95 % relative humidity at 55 °C. A potentiometer allows sensitivity adjustment and indicator LEDs show status. Builders who need a quick-disconnect fitting, remote-teach setup, or hazardous-area certification should look at other models.

3.5 m Maximum Sensing Distance

The 3500 mm range determines whether this sensor reaches the target in your application; if the required detection distance exceeds this figure, a different sensing mode or model will be necessary.

Questions about this item

Will the 2 m cable or the PMMA lens need periodic replacement on the QS18APWLP?

The 2 m cable is fixed and the PMMA lens is sealed inside the ABS housing; neither is designed as a user-replaceable part.

What is the first limit reached when the sensor runs continuously at 70 °C ambient?

The 70 °C maximum operating temperature is the primary thermal limit; the ABS housing and IP67 seal are rated up to that point.

How much heat does the 20-140 V ac/dc supply generate during all-day operation?

Power draw is low for a photoelectric sensor, so self-heating stays well below the 70 °C ceiling; the unit runs cool enough for continuous duty.
