PALLET SENSOR ASSEMBLY

摘要

A pallet sensor assembly for a passenger conveyor includes a proximity sensor and a limit switch. The proximity sensor detects the presence of the pallets and the limit switch monitors the wear of the pallet assembly. Neither sensor is in direct contact with the pallets during normal operation of the passenger conveyor. Both sensors are mounted and positioned on a single frame that is then mounted onto the pallet assembly. The pallet sensor assembly is positioned such that the passenger conveyor may be stopped prior to exposure of the opening caused by the missing pallet or exposure of the worn pallet to the passengers.
