Photoelectric sensors and proximity sensors in miniature housings

Product Discontinuation Notice

Our F 20 products have been produced in the same high quality method for many years. Our target is to deliver you the best product for your applications therefore we introduced some time ago the innovative F 25 series that replaces now the F 20 series.
 
You can find the products concerned, the date of the last order possibility and an alternative product out of F 25 series which improved performances in the table below.

We hope that we don’t couse so much efforts to change to follow up products.

For sure, our technical sales department or application department supports you. With this help we hope that we can offer you the best follow up product for your application.
