A Sensopart UK product story
Edited by the Engineeringtalk editorial team Feb 10, 2005

The latest from the Sensopart line of F20 sensors is a retroreflective device designed for the detection of transparent materials, especially glass containers.

The latest from the Sensopart line of F20 sensors is a retroreflective device designed for the detection of transparent materials, especially glass containers.

The miniature sensor uses the autocollimation principle allowing it to detect transparent materials of any shape throughout the entire detection range.

Reflections of mirroring surfaces are effectively suppressed by the polarisation filter fitted to the sensor window.

It has been specifically designed for applications in bottle detection in bottling plants, ampoule detection in the pharmaceutical industry and sensing of transparent foils in the food industry.

Measuring just 32 x 20 x 12mm, the compact FR20 RG1 sensor fits easily into restricted spaces.

It has a working distance of 5 to 500mm and is temperature compensated to ensure reliable switching throughout the entire temperature range of -20 to +60C.

It uses red light at 660nm pulsed and its contacts are selectable as normally open or normally closed, with small hysteresis over the switching cycle.

It can be configured easily and conveniently using teach-in.

Robustly constructed in ABS material and offering protection to IP67, the FR20 is available with a choice of connector or cable fittings.
