This position sensor is most commonly used for measuring flap and cowling travel. The position sensor gets wired to Ray Allen’s RP3 indicator. However, if you are using a glass panel, this position sensor would be wired to the position senors on your EIS module.
Made by Ray Allen:
The Ray Allen POS position sensor provides a signal for a RP3 indicator or a glass panel display by means of a sliding arm.
The sliding arm is connected to a 0-5K ohm pot. Install the position sensor where the arm can travel just under its full length.
See Ray Allen’s Instructions POS RP3 for more information.
