Fully automated production enables us to offer these high quality sensors at an extremely attractive price. The M18 Series are available as thru-beam sensors, retro reflective sensors (with and without polarizing filter) or diffuse reflective sensors. These four sensor variants, plus a selection of reflectors, holders and cables provide solutions for almost all optical sensor applications. In the most simple case, cylindrical sensors require a simple drilled hole for mounting. Combined with an appropriate connector, installation is a matter of minutes, which is also a great advantage for service work.
