The SICK T4000 Standard Series Safety Switch is a transponder sensor that offers a high level of prevention against tampering due to the individually coded actuators. It is comprised of several components, including a sensor, coded actuator and an evaluation unit. The sensor is compactly design for fast and easy mounting. Evaluation takes place centrally in the control cabinet. The T4000 Direct Series features a high level of machine availability due to tolerance for door misalignment, shocks and vibrations. An ATEX rated variant is available for Zone 2 hazardous locations, please contact a Motion World engineer for more details.
