Proven, endurance and longevity

The classic temperature switch or Hot Metal Detectors (HMD) of Proxitron are a success story. About a switch with 10 steps, the response temperature - varied between +250 ° C and +900 ° C – can be adapted to the conditions of application. What Proxitron has given the new HMD 4.0 series, has been found in these sensors in thousands of times as a great success – often for decades. It is the robust construction in stainless steel housing, a wide range of accessories incl. the protection options for the cable and of course, the longevity and the maintenance-free of these special sensors.
