HAL1506 UA Application Field and Working Principle

HAL1506 UA is a kind of magnetic switch, also known as Solid State magnetic switch. This technology is well-suited for applications requiring a reliable sensing of change in velocity, bi-directional on off current, and temperature signal. It is commonly used for hall effect sensors, solid state relays, and linear current switches.

Application Field of HAL1506 UA

HAL1506 UA is mainly applicable to motor support, bicycle speed measurement, engine or other mechanical system monitoring. It has a wide response range from 0 to 6000RPM, so it is suitable for a range of speeds and rotation levels. It features an adjustable Hall effect threshold that allows users the option to adjust the sensitivity and accuracy of the switch. Furthermore, it is designed to operate under severe environmental conditions such as high and low temperature, vibration, shock and electrical noise immunity and has high quality and stable performance.

Working Principle of HAL1506 UA

HAL1506 UA is specialized in detecting motion and movement. In general, it uses the Hall Effect principle to measure the speed or direction of a moving object. The hall effect switch consists of numerous small magnets along a circuit board. The magnitude of magnets varies with the type of application. When a moving object passes near the magnets, a voltage ((VHE)) is generated in proportion to the magnetic flux density (B), velocity (V), and constant (K). The ratio VHE/B is referred to as Hall coefficient. The hall coefficient is further affected by temperature, which can in turn affect the signals output of the switch. It is designed with temperature compensation feature to take temperature’s effect into consideration, so that it can maintain its accuracy and consistency.

Conclusion

HAL1506 UA is a reliable and accurate magnetic switch. It is specially designed for detecting motion and movement due to its response range of 0 to 6000RPM. It uses Hall Effect principle to measure the speed or direction of a moving object. The Hall coefficient for the switch is affected by the temperature, which the temperature compensating feature of the switch takes into consideration to maintain its accuracy and consistency.
