Dual output rotary speed sensor hall effect
Description
Yuli Intelligent YH-104X series speed sensors are designed for sensing target’s movement such as rotational speed, direction and position. With Hall-effect integrated circuit (IC) and a permanent magnet(samarium cobalt magnetic material) all sealed inside the rugged and probe-type package (PA66+GF30 engineering plastic/brass),the IC detects alternation of magnet’s flux density when it approaches a ferrous metal target which is usually a gear wheel composed of Fe Co Ni materials(e.g. silicon steel ) or a permanent magnet. When the gear wheel rotates, the sensor will generate two square-wave pulses (e.g. A and B) whose quantity is proportional to quantity of gear convex poles. This sensor is featured with outstanding performance of resistance to vibration and high operating temperature. With EMI radiated immunity protection built in, it can resist to great impulse of external current and voltage.

Principle
Connection
The output of the sensors is sinking current NPN (open collector). A pull-up resistor (1.5kΩ-2kΩ) should be connected to the sensor output circuit (between power supply Vcc and output). Please connect the pull-up resistors of both outputs before switching on the power supply.
