Application Field and Working Principle

The TIPL402 is perfect for a variety of applications, such as temperature measurement, speed sensing, encoder counting, and automatic control. It is compatible with almost any hall-effect sensor, including but not limited to the Honeywell 5001 series, the Siemens / Celduc Bistable Safety Switches, and the Panasonic EVQ-PJP series.

The working principle of the TIPL402 is based on the hall effect produced in a magnetic field. When a beam of light strikes a metal, the light is reflected back to a detector, which generates an electrical current. This current passes through a Hall-effect device, which produces a magnetic field based on the current. When a sensor is placed near the Hall-effect device, this magnetic field will induce a voltage between two points on the sensor. This voltage is then used to control the output of the sensor.

The TIPL402 evaluates the output of the hall-effect sensor and outputs a digital signal. The output can be configured to be either up or down, depending on the requirement of the sensor application. The status output pin can also be used for monitoring the flow rate of the sensor, since it changes whenever the sensor output changes. The reference pin can also be used to set the required output of the sensor.
