Norstat would like to introduce the TG1 from Mechan Controls, a safety tongue interlock that is designed to fit hinged, lifting or sliding guard applications.
The TG1 Tongue Guard Safety Interlocks were designed to be an easy and affordable method of keeping a machine safely guarded. With three versions available ( ABS, 316 Stainless Steel and ABS w/ Stainless Steel head ) the TG1 is suitable for most any type of application or production environment. The TG1 can be used to achieve Cat 4 / SIL3 PL-e when combined with a safety relay that monitors dual contactors through the safety relay reset channel.
