WM800 - Contact Sensor

WM800 - Contact Sensor

The WM-800 is a rotary potentiometer position sensor, in which a conductive wiper is in contact with a resistive material. The wiper is attached to a rotor. As the rotor is moved in either direction there is a change in the resistance, which is proportional to absolute rotation.

Typical output signals can include:

• Two electrically-isolated linear ratiometric outputs
• One linear ratiometric outputs and up to two idle validation switch (IVS) circuits

Ratings are as follows:

Electrical

• Linear ratiometric circuits operate from ±5VDC supply
• IVS circuits operate up to 28VDC dependent on configuration and the input electric load

Mechanical

• Packard Electric “Metri-Pack” Series 150 Connector
• Up to 54° of rotation
• 10-million endurance cycles
• 40-million dither cycles

Environmental

• Williams Controls Environmental Test Specification WDS-010
• Ingress protection ratings IP66

Note:

These specifications represent the expected minimum performance of the sensor. This information does not constitute a warranty that the product will meet the above specifications while used in specific applications or test equipment. Specific requirements may vary, based on the sensor configuration.
