LIMAX4R Shaft Information System Safe, absolute measurement for hoisting heights up to 1.500 m

The sensor is designed to be used as a safe sensor together with a safe evaluation unit or directly with a safe controller. In combination, the complete system is able to fulfil safety functions in the elevator in accordance with EN 81-20. LIMAX44 RED is available in two versions. In the unguided version, the magnetic tape is glued directly to the guide rail of the elevator. In the semi-guided version, the magnetic tape is mounted freely suspended in the shaft with the aid of a mounting kit. The tape guide integrated in the sensor serves to maintain the required reading distance.
