The BR2A-4mm is a 12mm threaded device that works in exactly the same way as the standard version (BR2A), however it is specially designed with a larger sensing distance of 4mm - ideal for positionings where there might be slight movement tolerance such as pick-ups on wheel extents, where the movement is too great for the Standard Wheel Sensor.The more pick-up's available the more accurate the tripmeter will be.
An alternative positioning for this type of sensor is to pick up on flying tabs (minimum of 2 positioned 180* apart) fatened on the bolts of the Prop Shaft's Universal Joint.
N.B. Old tripmeters (Pre-2005) can be upgraded to work with this sensor at the Brantz factory for a small charge, or free of charge if the meter comes in for a service.
