Hengstler is a leading European manufacturer of industrial components for counting and control applications, such as counters / timers, rotary encoders, industrial and temperature controllers, relays, and printers and cutters. Today’s automation leaders are seeking solutions that will enable machines with advanced analytics, condition monitoring and predictive maintenance, while also offering improved efficiency, and fast time to market. None of these alone are easy challenges. However, your competitors are launching new solutions at an increasing rate meant to meet these challenges.

Hengstler has created SCS Open Link, an open communication platform that provides high performance data transmission over a cost effective single cable solution, designed to quickly and efficiently connect rotary encoder and other sensors to edge computing and Industry 4.0 solutions.

From cost-aware standard types through to extremely robust heavy-duty products, HENGSTLER can supply the right incremental rotary encoder for every application. With optical incremental rotary encoders, a line-coded disc made of metal, plastic or glass and mounted on a rotary bearing interrupts a beam of light from a light-emitting diode. The number of lines determines the resolution, i.e. the number of measured points in one revolution. The interruptions of the light beam are sensed by the receptor element and electronically processed. The information is then made available as a rectangular signal at the encoder output. HENGSTLER can provide rotary encoders with up to 10,000 pulses per revolution.

The universally applicable industrial incremental encoders in the RI58 family are characterized by being particularly flexible. There are a number of different versions offering a range of flanges and connections. These encoders are suitable for high shock loads and feature high signal accuracy and up to 40,000 steps with 10,000 marks and are particularly well suited to use in machine tools, CNC axes, packaging machines, motors / drives, injection molding machines and sawing machines.
