Foot brake proximity switch 701/80398 JCB, aftermarket

Foot brake proximity switch 701/80398 is an aftermarket part for the JCB machines.

This part is an inductive proximity switch that detects the brake pedal position on JCB machines. According to sources, 701/80398 is the foot brake proximity switch used on JCB Loadall telehandlers; the product card lists it as a brake light switch under the number 71/80398. When the pedal is pressed, a metal target comes in front of the sensor, which signals and lights the brake lamps; on some machines the signal is also used in transmission control. A faulty sensor leaves the brake lamps dark or permanently lit. Brake lamps show following traffic that the machine is slowing, so a sensor fault is not put off. If the sensor has an LED indicator, it lights when the pedal is pressed, which makes adjustment easier.

Fitting

The sensor screws into its bracket by its threaded body and is locked by two lock nuts, the gap to the target being set by turning the nuts. Too large a gap and the sensor misses the target; too small and the target can strike the tip. Secure the cable with ties away from moving parts and test the function.
