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.

High-Voltage Relays Type 509

To ensure that our relays as used in your applications carry on doing their job reliably for years, the quality of products bearing the HENGSTLER name is the highest priority. All our locations are certified to ISO 9001 and ISO 14001, and the entire product range is, as you would expect, in conformity with RoHS and REACH regulations. With over 50 years' experience in the field of high-voltage relays, HENGSTLER can provide numerous solutions for a wide range of requirements.

Wherever high voltages have to be reliably switched on or - more importantly - off, HENGSTLER H-509 high-voltage relays are to be found. The H-509 relay is available with one NOC or one NCC, each of which is rated for 5 kV switching voltage. H-509 high-voltage relays conform with standard IEC EN 61810-1.
