The HAL-506 Hall Effect Tachometer Sensor is a compact, enclosed sensor widely used in industrial automation, automotive, aviation, and other fields. Its core principle is based on the Hall effect. When magnetic flux lines pass through the sensing element of the sensor, a Hall voltage is generated. This voltage is then amplified and shaped by the Hall chip to form a stable electrical signal for use with secondary instruments.

The HAL-506 features several notable characteristics. Firstly, it is highly stable and can operate reliably in complex industrial environments over the long term. Secondly, it has low power consumption, making it suitable for use under various power supply conditions. Additionally, the sensor is highly resistant to electromagnetic interference, ensuring accurate signal output even in environments with significant electromagnetic noise. The HAL-506 also operates across a wide temperature range, from -20℃ to +80℃.

In terms of technical specifications, the HAL-506 has a measurement range of 1Hz to 45KHz, which meets the needs of most industrial applications. Its output signal is a rectangular wave, with a high-level voltage close to the supply voltage and a low-level voltage not exceeding 0.5V, ensuring signal stability and reliable transmission. The sensor operates on a supply voltage ranging from 4.5V to 24V DC, making it highly adaptable.

In practical applications, the HAL-506 is easy to install and use. Simply attach a small magnet to the rotating object, fix the sensor at a certain distance from the magnet, and align it with the S pole of the magnet to start the measurement. This design not only improves measurement accuracy but also significantly reduces installation costs and complexity.

With its outstanding performance and broad application scope, the HAL-506 Hall Effect Tachometer Sensor has become an indispensable tool in many industrial fields.
