Capacitive Sensors

Capacitive Sensors

Contact as well as non contact capacitive sensors work by measuring changes in an electrical property called capacitance. Capacitance describes how two conductive objects with a space between them respond to a voltage difference applied to them. High switching distance up to 30 mm even through non-metallic walls. Absolutely reliable even when interfered by ambient conditions. Absolutely reliable detection of objects such as wafers, PCBs, paper stacks or hot adhesives up to 200 °C

Key Features

Independent of color, gloss or surface properties
Insensitive to dust and dirt
Robust construction in hygienic design
Sensors with flush installation are especially recommended for non-conductive (dielectric) media
Detection regardless of transparency or brightness of the objects
Large sensing distances ensure reliable box detection .

Applications

Adhesive liquid level detection
Plastic granules detection
Presence detection of plastic boxes
Wafer detection in solar cell manufacturing facilities
Granulate bulk goods detection in injection molding plants

Photoelectric Sensors

Photoelectric Sensors

A photoelectric sensor, or photo eye, is an equipment used to discover the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver.

Ultrasonic Sensors

Ultrasonic Sensors

Ultrasonic sensors are used around the world, indoors and outdoors in the harshest conditions, for a variety of applications. Ultrasonic sensors use high frequency sound waves to resonate a desired frequency and convert electric energy into acoustic energy, and vice versa. Sound waves are transmitted to and reflected from the target back to the transducer. Targets can have any reflective form, even round. Certain variables, such as target surface angle, changes in temperature and humidity, and reflective surface roughness, can affect the operation of the sensors.

Inductive Sensors

Inductive Sensors

Inductive sensors are used for the detection of conductive objects such as metals and carbon. Inductive proximity sensors are used for non-contact detection of metallic objects. Their operating principle is based on a coil and oscillator that creates an electromagnetic field in the close surroundings of the sensing surface.

Applications

Presence detection of a machine component
Counting metal objects (e.g. in component feed or conveyor technology)
Presence detection of objects in process
Ultra precise referencing of the zero position of a moving machine component (e.g. in robotics)br /> Rotary speed measurement on metal gear wheel

Magnetic Proximity Sensors

Magnetic Proximity Sensors

The magneto-resistive element is made of a special material which only reacts to magnetic fields, for example a permanent magnet, and provides a digital signal at the output. Detecting even very weak magnetic fields, the magneto-resistive element is approximately ten times more sensitive than a Hall element which enables a large switching distance. Magnetic proximity switches are omni-polar, meaning both North and South pole are being detected.

Precision Mechanical Switches

Precision Mechanical Switches

A strong focus in the My-Com design was limiting the number of components to the absolute minimum. Just three moving parts and high-quality materials guarantee an enormous number of switching operations with constant repeat accuracy. Short, linear travel in just two directions and sensitive to even the slightest activating force further increase both reliability and service life of the My-Com precision switch, which has been proving absolute reliability in over 1 million applications
