Description of SICK Incremental Encoders SICK Incremental encoders generate information about the position, angle, and rotation counts. The resolution is defined in the number of lines or pulses per rotation, which the encoder transmits to the control unit for each rotation. The current position can be determined by the control unit by counting these pulses. […]
Eltra lines of linear encoders, potentiometers, and magnetostrictives The Eltra linear transducers serve for the measurement of linear displacements. The potentiometers consist of a wire or a metal layer, wrapped on an insulating support, and a moving contact able to move along the conductor. The operating principle is based on the variation of resistance in an electrical circuit determined by […]
Eltra Rotary Absolute Encoders with absolute rotary encoders provide a uniquely coded numerical value for each mechanical shaft position, memorizing the value of the current position and thus avoiding the loss of information in case of restart of the machine or interruption of the power supply. Thanks to the many advantages of this type of […]
Overview Everything flows, nothing stands still. Nothing endures but change. And nowhere is this more evident than when reviewing one’s own heritage. And that began for Hengstler over 150 years ago. Back then, in 1846, Johannes Hengstler, a watchmaker in Aldingen, in south-west Germany, started mass production of gong springs for clocks. As the decades […]
