Levelling sensor: GLS TK

Product Overview

The elevator levelling sensor GLS-TK is built for use in TK Elevator (formerly ThyssenKrupp) lift systems. It is a non-contact photoelectric sensor designed to monitor car position inside the lift shaft.

The sensor operates with fixed targets placed at each landing. When the lift car aligns with the target, the device changes its signal state. This confirms that the car has reached the correct level and is within the door zone.

Accurate levelling helps reduce trip risk, supports smooth door operation and limits wear on mechanical parts. The GLS-TK sensor is used in both commercial and residential buildings where correct floor alignment is required.

Each unit should be installed and tested by qualified lift technicians to ensure safe and proper operation.
