WM810 - Non-Contact Sensors - Dual Hall-Effect

The WM-810 is a solid-state rotary position sensor that provides a dual linear output voltage proportional to absolute shaft rotation in either direction from a reference angle. It works on the Hall-effect principle, wherein the magnet rotates in the sensor rotor and the Hall-effect sensor is mounted to the stationary body. When the magnet, which is mounted on the rotor, is rotated from the low endstop to the high endstop, there is a change in the magnetic flux sensed by the Hall-effect sensor. The change in the magnetic flux results in an output voltage proportional to the supply voltage (5VDC).

Typical output signals can include:

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

Ratings are as follows:

Electrical

• Supply pin protected against short to -15Vdc and +30VDC
• Supply pin protected against short to battery up to 30VDC
• EMC/EMI Resistance per SAE J1113-1

Mechanical

• Packard Electric “Metri-Pack” Series 150 Connector (standard)
• Up to 70° of rotation
• 10-million endurance cycles

Environmental

• Williams Controls Environmental Test Specification WDS-010
• Ingress protection ratings IP67 and IP69k
