Tongue Guard Safety Interlock Switch
July 1, 2025
Norstat has introduced 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 applications or production environments. 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.
The TG1 has three types of actuators available (standard, flat and flexible). The flexible allows for gate sagging or misalignment, allowing the switch and activator to function without damage on applications where there may not be proper alignment. These switches have force guided relays, tamper resistant mechanisms, three cable entry point, are shock and vibration proof and have a protection rating of IP67.
