|
The STPS operates via
a non-contacting magnetic proximity sensing device combined with a simple
electronic circuit resulting in the ability of producing two separate and
distinct logic level signals.
The STPS output signal
is altered by the proximity of a separate ferro-magnetic shunt, which is
linked via the seat track. The logic signal produced is the result of the
proximity device being activated or deactivated.
When the seat is in
the forward position zone of the track, the sensor gives a low current
(prohibit) signal. When the seat is in the rear positon zone of the track,
it gives a high current (enable)
signal. |
