Klaschka sensors in industrial plant and machinery are basic elements for automation. Since these non-contact, free-of-wear sensors work contactless and have no effect on the part they detect, their service life is almost unlimited. They are insensitive against pollution and can be used for a large ambient temperature range. 

Proximity switches detect, with short response times, the final and intermediate positions for rotary and linear motions of machine parts.

Fast pulse sensors, equipped with evaluation devices, determine incrementally the rotational speed, stroke rate, and frequency as well as the position and the speed of moving machine parts. 

Distance and position sensors supply either a current or a voltage (as option) which is analog to the measured variable. They are inexpensive absolute-value-devices with short operating times.

For the contactless detection of metals. The sensor consists of a coil, which is part of an oscillating circuit in a measuring oscillator. The switch responds to all metal types. Concerning the " all metal" version, the switching distance is the same for all metals. >> go to Inductive Proximity Switches

For the contactless detection of motions with high frequency. Rotation speed sensors and speed pick-up encoders (mini-encoders) either have a hall element, a magnetically changeable resistsance or an inductance as sensing element. The maximum switching frequency is 25 kHz for switching distances > 2 mm. Also available as Double Pulse Sensor with integral detector for identifying the direction of rotation. >> go to Pulse Sensors

WIDENT/P position detector: Detection of several positions on, for example, shutter gates or rotary tables. WIDENT detection system: For robotics tool change couplings. >> go to RFID Identification

Ultrasonic sensors are suitable for large distances. These acoustic sensors have a piezo-ceramic sound converter, which emits pulse packages and receives the reflected pulse packages in turn. The distance of the object is determined by measuring the running time. >> go to Ultrasonic Sensors

Capacitve sensors are used for the detection of various materials (e. g. paper, plastic, wood). The configuration corresponds to that of the inductive proximity switch; the sensor element, however, consists of a capacitor. The sensor responds to conducting materials, i. e. apart from metals also to wood. >> go to Capacitive Sensors

Sensors with special properties as well as customer-specific design. Examples are sensors for the thickness measurement, for film recognition, spark detection, pulse rate switches, inductive ring- and fork-shaped switches with the associating evaluation devices. >> go to Special Sensors
