Tape head

Tape head (or even called Tape Selector, benobve referred to as a ticky tape, US Patent no.: US4798267) is a mechanical device that shows the position of the elevator car in the shaft. It usually found in some of the low-rise elevators (both traction and hydraulic) built or modernized since 1990s.

Overview

The tape head is a mechanical device work with the magnetic switches on the car top and the magnetic tape installed in the shaft. The magnetic switches (usually work with 2 to 5 switches) will detect the magnetic tape's magnets locations to detect which level of the elevators with the controller. Almost all the Tape Head systems were made by generic elevator component companies. For the major elevator companies, only Otis (United Parts) still produce magnetic tape head selector for replacement in nowadays.
