Why choose a polarised retro-reflective sensor
A retro-reflective sensor sends light to a reflector and receives it back. A plain version can be fooled by shiny objects that reflect light like a reflector. A polarised sensor uses filters so it only accepts light returned by a micro-prism reflector, which shiny objects cannot imitate.
That is why the SSP/AP-1H is a good choice for glossy cartons, cans, foil and stretch-wrapped products. Use it with a micro-prism reflector such as the Datalogic RL 201.

Why choose the Micro Detectors SSP/AP-1H
- Polarised filter: no false triggers from shiny objects
- 2 m range: covers most conveyor widths
- M18 body: fits standard brackets
- PNP NO: standard sourcing PLC logic
- Single-side wiring: only the sensor needs power
Typical applications
- Object detection on conveyors
- Glossy carton, can and bottle detection
- Door and gate monitoring
- Packaging and material-handling machines
Installation and setup tips
Mount the sensor facing a micro-prism reflector across the conveyor, within 2 m. Align the beam using the indicator LED. Wire brown to +24 V, blue to 0 V and black to the PLC input. Use a micro-prism reflector, not reflective tape, so the polarisation works correctly.
