STS Steering Sensor
3500 Annapolis Lane North, Minneapolis, MN 55447
Telephone: (763) 509-2084 Fax: (763) 559-0108
GENERAL DESCRIPTION
The STS Steering Sensor is intended to provide an electrical steer signal input to a control device such as a DC2 or
SUSMIC10. The signal is generated by rotary shaft motion and is converted to an electrical output by a long life
potentiometer. The shaft is suitable for mounting on available commercial steering wheels. This sensor is intended
to be used outdoors on mobile equipment. This is a friction-held device. Cable assembly comes out rear of unit.
Dimensions of the 1090199 STS Steering Sensor in millimeters [inches].

OUTPUT CHARACTERISTICS
INSTALLATION
Apply 68 ± 6.8 N•m [50 ± 5 lbf•ft] of torque to the nut that secures the steering wheel to the steering sensor. This
torque specification conforms to SAE J511 FEB94/ISO 5010 (general requirements 3.1 and 3.2 also all steering systems
8.1.1) pertaining to steering for off-road machines with rubber tires.
WWARNING
Take appropriate diagnostic and failure mode corrective action. This control device has a positive voltage reference.
A wiring short may produce an unintended output signal causing unwanted output and machine motion.
WWARNING
Provide an emergency shut down and/or braking system sufficient to immediately stop the system or vehicle. A
sensor failure may cause an output which could activate a valve or pump. If this occurs, the apparatus may move,
possibly endangering people or equipment.
