Siemens 3TK2806-0AG2 Safety Contactor Combination

Siemens 3TK2806-0AG2 is a contactor safety combination for safety circuits enabling and signaling, featuring 5 normally open contacts and 1 normally closed contact (5 NO + 1 NC) with a self-latching mechanism (K1) and AC operation at 110 V, 50/60 Hz. This unit is designed to energize and hold the safety path in emergency-stop and guard-monitoring applications, aligning with Siemens guidance for 3TK28 safety-relay combinations. It is intended for use in safety circuits where a reliable enabling and signaling interface between the control system and safety devices is required, such as guarding, interlocks, and other protective equipment scenarios. As part of the Siemens 3TK28 family, the 3TK2806-0AG2 combines a contactor with a dedicated safety function to ensure proper fault-detection and control in industrial automation environments.
