Approx. 6000 products

Robust and highly reliable, Contrinex inductive sensors are the fit-and-forget choice for non-contact detection of metallic targets at distances up to 40 mm. Vacuum-encapsulated electronics and metal housings protect against shock, vibration, dust, dirt and moisture, making inductive sensors ideal for highly demanding conditions.
An inductive sensor generates a magnetic field that is attenuated by a metal target. As a sensor nears its target, a sensing circuit detects the degree of attenuation and switches the output accordingly.
Versatile and highly sensitive, Contrinex photoelectric sensors deliver long-distance, non-contact detection of metallic and non-metallic targets, accommodating variable target color and surface finish. High-frequency switching circuitry senses small, fast-moving objects, even against non-contrasting backgrounds.
Contrinex ultrasonic sensors provide reliable, non-contact detection of solid,liquid, granular or powdered materials in air, tolerating precipitation, humidity, dust and fumes.
Target materials may be colored, transparent, polished or matt; detection is practically independent of the target’s direction of travel. Diffuse-mode and reflex sensors emit bursts of high-frequency sound waves toward a target, measuring the time elapsed until an echo is received.
Robust and extremely versatile, Contrinex capacitive sensors detect position or presence of conductive and non-conductive materials, including liquids, pastes and bulk solids. Capacitive technology permits detection of targets through thin non-metallic barriers, ideal for controlling packaging and filling processes.
Safetinex light curtains and access control barriers have been designed by Contrinex to provide high quality safeguarding for both personnel and machinery. The full range comprises light curtains of Type 2 or 4 according to the international standard ISO 13849.
Resolution is suitable to protect hands (30 mm), fingers (14 mm) or full body (3 to 6 beams).

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. Thanks to non-contact switching and coded communication, the service life of these compact sensors is very long.
