LIMAX - leading in shaft copying

The ELGO Group has been developing and producing magnetic tape-based measuring systems for position determination in lift systems since 2002. ELGO Batscale AG in Liechtenstein functions within the ELGO Group as a competence centre for the further development of this technology. Thanks to continuous development and consistent compliance with elevator relevant standards, ELGO Batscale AG has succeeded in further expanding ELGO's market-leading position.

LIMAX shaft information systems use magnetic tape technology to record the position of the elevator car in the shaft with high precision. The principle is very simple: A sensor mounted on the elevator car detects the current absolute car position using Hall sensors, which scan the magnetic tape mounted in the shaft without contact. In this way, the position of the car can be determined at any time with high accuracy.
LIMAX sensors can be used to reduce structure-borne noise according to DIN8989.
Our product portfolio comprises three product lines which cover different requirements for shaft information systems:

LIMAX Standard

The LIMAX STANDARD range includes entry-level models for different conveying heights and speeds. The linear measuring systems are compact and ideally suited for modernization and retrofitting.


NEW! / mini-shaft information system / only 82 x 68 x 30 mm / pseudo-absolute shaft copying / for conveying heights up to 90 m


absolute shaft copying / for conveying heights up to 130 m / compatible with almost all common elevator controls


All sensor systems of the LIMAX RED series are redundant and SIL3 certified. In combination with a safe evaluation unit (Safe Box) or a safe elevator controller, they can be used for safety-related applications up to SIL3. 


safe shaft copying / SIL3 certified /  in combination with a safe elevator control or the Safebox safety functions up to SIL3 are possible / for conveying heights up to 260 m


safe, absolute position detection for high-rise elevators / unguided and semi-guided variants / noise-free technology

evaluation electronics / use with LIMAX3R or LIMAX4R / up to 3 safety relay pairs / up to 5 safe inputs, 1 output

LIMAX Compact

The measuring and safety systems of the LIMAX COMPACT series offer absolute, redundant position detection and safety monitoring in one housing. 


NEW!  safe, absolute shaft copying / safety-relevant switching and control functions are integrated in the sensor housing / for hoisting heights up to 130 m / complete safety actuator system is electronically designed / safety functions can be flexibly adapted to the elevator system on site.


safe, absolute shaft copying / safety-relevant switching and control functions are integrated in the sensor housing / for conveying heights up to 260 m
