Elevator electronics and sensors
Design and localization of an electronic elevator floor selector and a 32-sensor door light curtain.
This set includes the SLF/LEF floor selector board and the elevator door light-curtain sensor. In the course of its development, the floor selector was upgraded from an electromechanical to an electronic design, and the light-curtain sensor with a 32-sensor array was designed and localized.

Product overview
The developed prototype has passed operational tests and one month of load testing in a 15-unit residential complex and is ready to enter production. This set can be produced to customer requirements and order, and its configuration must be matched to the target elevator system.
