The German WAGO Wanke SGA safety switch corresponds to the all-metal version of the STA safety switch. Like the safety switch STA and the plastic-clad safety switches STP and SGP, the SGA has the same metal actuator head and the same actuator. Therefore, the safety switch STA (with door lock) or SGA (without door lock) can be used in the system as required. Altrona offers switching elements (positive drive normally closed) in a variety of contact combinations for the SGA product line. All models can implement dual - channel wiring for large safety differences. The safety switch SGA is also suitable for safety control systems considering the special characteristics of the small switching current of 1 mA at the switch contacts. Features the same drilling pattern as the STA, the highly demanding alloy version of the same actuator uses flexible connection options with three cable entrances to highly protect such IP 67
