Sensors, Light Curtains
Contrinex is a leading manufacturer of sensors for factory automation. The Swiss company has a unique and innovative range of products whose features far surpass those of standard sensors.
Proximity switches are about detecting movement and maintaining quality control. Contrinex proximity switches are able to reliably deal with the most critical demands for information. These switches feature all-metal housings, right-angle optics, and analog outputs.

Contrinex also produces some of the most advanced light curtains in the industry. They are used in a wide variety of applications ranging from the industrial press machine to the pharmaceutical assembly line. For any machine requiring a fixed guard-door or cover, Contrinex also proposes safety sensors with either a magnetic or RFID operating principle. Magnetic sensors are a very economical way of monitoring whether a door is open or closed.

The Smallest Inductive Sensor in the World
Just twelve millimeters in length and three millimeters in diameter – these tiny dimensions make the MiniMini the smallest inductive sensor in the world.
The MiniMini impresses with its high switching frequency of 8 kHz and excellent temperature stability from -25 ° C to +70 ° C. Alongside the standard version with a plastic cap Contrinex also offers a version with a ceramic sensing face. This type is pressure resistant up to 200 bar and has IP68/IP69K protection. With a plastic cap the switching distance is 1 mm; with a ceramic cover it is 0.8 mm.
