CAUTION:
• Vehicle OEMs must insure that the unmated connectors are protected
against paint spray during vehicle assembly.
• The sensor wire harness connectors must be properly seated with the seals
intact and undamaged and the secondary locks snapped securely in place.
Failure to do so could result in moisture or corrosion damage to the
connector terminals. BCVS may not provide warranty for sensors displaying
this condition.
• Follow all connector manufacturer requirements for the fabrication of all wire
harnesses.
• Wire harness lengths must be carefully selected. Harnesses of excessive
length increase the possibility of parasitic interference and wire damage.
Harnesses that not long enough can cause the wire to break or can subject
the wire to mechanical strain that in turn can lead to failure of the wire.
• Excess lengths of wire are not to be wound to form coils.
WARNING:
• All wires must be carefully routed to avoid contact with rotating elements.
• Wiring must be properly secured as described below using UV stabilized,
non-metallic hose clamps or bow-tie cable ties to prevent pinching, binding or
fraying.
• BCVS may not provide warranty coverage for sensors with damaged wiring.
6.3 Exciter Ring Installation Requirements
See BW-120-A, Application Specification, “Wheel Speed Sensor Customer Interface
Recommendations” for details.
6.3.1 Material
The exciter ring material must be permeable and of low magnetic retentively.
Examples of suitable exciter ring materials include machined, quenched and
drawn steels.
6.3.2 Installation
Exciter rings are typically pressed on to the hub by the hub manufacturer.
If a wheel hub is not available with an exciter ring installed, an exciter ring may
be purchased separately and pressed on to a properly prepared hub. A 0.004
inch (0.10mm) interference fit is required between the outer diameter of the
machined hub surface and the inner diameter of the exciter ring
4
. It is important
that this relationship is established and maintained under all operating conditions.

If the exciter ring is made of powdered iron (sintered), consult the manufacturer for specific instructions
on how to install this ring on to the hub.
