The MFM7-DHS1-5KCD4 Hall Effect Dual Switch Sensor produces dual pulsing outputs, 1 south pole and 1 north pole. Dual output Hall Switch Sensors function as a directional limit switch. “DHS1” type Dual Hall Effect Sensors have a 55 gauss operate point. The MFM7-DHS1-5KCD4 Dual Hall Switch Sensor has an NPN input with a 5k pull up resistor. Furthermore, the sensor is potted in a flange mount housing with Deutsch DT04 4-pin connector.
When the south pole element is close to the sensor face, channel A output goes low and the sensor switches on, while Channel B output goes high and switches off. The sensor can detect the south pole magnet at a slightly greater operate gap than the north pole element. Conversely, when the north pole element is close to the sensor face, channel B output goes low and switches on, while channel A output goes high and switches off. So, a south pole detection turns channel A on, while a north pole detection turns channel B on.
No rotational sensor orientation is required for operation. Use the provided lock nuts to set the air gap from the target. Note: Operate and release gaps are dependent on the size, material, grade, and temperature of the target magnet.
Other features include:
- True Zero Speed
