The GUH35 intrinsically safe Hall sensor for mining is suitable for dangerous environments prone to coal dust and gas explosions in underground coal mines. As the detection head of the sensor approaches a magnetic object, the output signal will change after the distance reach the detection threshold. Hence, the sensor can be used for position, travel and limit detection of moving parts. The underground transportation equipment can realize accurate movement control when accelerating, decelerating or moving at a constant speed, and is able to stop within the designated area for safe operation. Featuring a compact and durable structure, this product is supported by a warranty period of 18 months, assuming no external.

When the Hall sensor moves within the detection range, its output signal will change. When the magnetic steel distance from the proximity switch detection head is within the effective distance, the internal resistance of the proximity switch will be less than 0.5Ω; when the distance is greater than 40±5 mm, the internal resistance will be changed back to greater than 5kΩ.
