Dual Hall Effect Switch |

Dual Hall Effect switch sensors produce dual pulsing outputs. 1 south pole and 1 north pole output. So, these non contact magnetic sensors function as a directional limit switch. First, mount the actuator magnets at each end of the range of motion. Next, set the air gap within range of the target magnets using the supplied lock nuts. Note that the sensor does not require orientation. Finally, when the south pole element is near the sensor face, channel A output is low and switched on. While channel B output is high and switched off. Notice that the south pole element will detect a slightly greater operating gap, given its closer proximity to the sensor face. Also, the target magnets' size, material, grade, and temperature determine the operating and release gap.

Dual Hall Effect switch sensors offer a greater detection gap than our standard DHS series. Other features include no wearing parts, true zero speed detection, and rugged sealed housing. All our Hall Effect sensors can be modified, enhanced, or updated with our modular features and functionality. Choose from various housings in aluminum, stainless-steel, plastic, threaded, flange mount, and customer specific. Available sensor functionality includes NPN, PNP, TTL, etc. Connectivity options such as Deutch, Amphenol and many others, free-end wires pigtails, any length.

S63B-DHS1-5KCB2A Hall Effect Dual Switch Sensor

The S63B-DHS1-5KCB2A 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 S63B-DHS1-5KCB2A Dual Hall Switch Sensor has an NPN input with a 5k pull up resistor.  Furthermore, the sensor is potted in a stainless steel 5/8-18 cylindrical housing with integral 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
  • Rugged, Sealed Housing
  • Greater Detection Gap than Standard DHS Sensor
  • Solid State (Nothing to wear out!)
S12-DHS1-5KSA5 Hall Effect Dual Switch Sensor

The S12-DHS1-5KSA5 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 S12-DHS1-5KSA5 Dual Hall Switch Sensor has an NPN input with a 5k pull up resistor.  Furthermore, the sensor is potted in a plastic M12 cylindrical housing with shielded 4-wire 22 AWG PVC cable.

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:

  • Rugged, Sealed Housing
  • Greater Detection Gap than Standard DHS Sensor
  • Solid State (Nothing to wear out!)
MFM7-DHS1-5KCD4 Hall Effect Dual Switch Sensor

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.
