TILT SENSOR

TILT SENSOR

Description

INFOID:0000000005249738

• The tilt sensor is installed to the steering column assembly. 
• The resistance of tilt sensor is changed according to the up/down position of steering column.
• The terminal voltage of automatic drive positioner control unit will be changed according to a change of tilt

sensor resistance. Automatic drive positioner control unit calculates the tilt position from the voltage.

TELESCOPIC SENSOR

Description

INFOID:0000000005249741

• The telescopic sensor is installed to the steering column assembly. 
• The resistance of telescopic sensor is changed according to the forward/backward position of steering col-

umn. 

• The terminal voltage of automatic drive positioner control unit will be changed according to a change of tele-

scopic sensor resistance. Automatic drive positioner control unit calculates the telescopic position from the
voltage.
