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. Patented Condist® oscillator circuitry allows best-in-class operating distances, while all-metal construction – including the sensing face – is possible with revolutionary Condet® technology. Designers everywhere specify Contrinex inductive sensors as industrial limit switches and position switches, as pulse-counting devices, or for distance and speed measurement.
A reflex, or reflective, photoelectric sensor contains a transmitter and a receiver in a single housing, and emits a pulsed, focused light beam through a polarization filter toward a distant reflector. Reflected light returns to the sensor, passing through a second filter before arriving at the receiver. When a target object interrupts the light beam, the receiver detects the reduced light intensity and triggers the sensor.
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. They contain a transmitter and a receiver in a single housing. Ultrasonic sensors are compensated for temperature variation, but are unsuitable for use with very hot targets. The technology is ideal for distance measurement and presence- or proximity-detection at moderate distances.
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.
