Abstract

A passenger sensor for a conveyor includes a transmitter assembly that is positioned within a channel in the conveyor balustrade. The transmitter assembly includes a plurality of transmitters that are spaced along a cable to form a transmitter chain. Each transmitter includes a module and a connector attached thereto. The transmitter assembly is disposed within the channel without the need for mounting hardware or openings within the balustrade for the passage of the cable. In a particular embodiment, a receiver assembly is disposed in a channel in the opposite balustrade in a similar manner.
