The A47-HS1-P5P21 Hall Effect Switch Sensor is a single digital output south pole sensitive proximity sensor with a 55 gauss operate point. “HS” type Hall Effect Sensors are hall switch sensors that turn on and off with a magnet. Since this sensor is south pole sensitive, it does not respond to north pole magnetic fields.
When the south pole magnetic field is present, the sensor switches on producing a low output. Conversely, when the magnetic field retracts the sensor switches off producing a high output. 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.
The A47-HS1-P5P21 Hall Switch Sensor has an PNP input with a 5k pull up resistor. Furthermore, the sensor is potted in a black anodized aluminum 5/32-32 cylindrical housing with wire leads.
HS1 Hall Effect Switch Sensors use square wave output pulses that can be used to detect speed, position, proximity, or count. Contact us with your specific requirements!
Other features include:
- Internal Hysteresis
- Lower Gauss Operation than Standard HS Sensor
- Solid State (Nothing to wear out!)
- Temperature Stable
