The GELBAU 252.06Z is a high-reliability safety switching device specifically engineered for the monitoring of safety contact edges with an 8.2 kOhm terminating resistor. This compact unit is an essential component in machine safety systems, designed to ensure the safe and immediate shutdown of hazardous movements upon detection of an obstacle. Housed in a slim 22.5 mm enclosure for DIN rail mounting, it saves valuable cabinet space. The device complies with stringent safety standards, including Category 3 and Performance Level ‘d’ according to EN ISO 13849-1, making it suitable for a wide range of industrial applications where operator and machine protection is paramount. It features two normally open (NO) safety relay outputs for integration into the safety control circuit.
