The CH442TB with Magnetic Sensors TO-92S RoHS is a semiconductor device manufactured by COSEMITECH. It is a dual, bipolar Hall-effect device, with two integrated magnetic sensors responding to the presence of alternating fields. This device is ideal for detecting speed, direction and proximity, as well as other tasks such as magnetic counter circuits, and can also be employed in industrial equipment, robotics, and instrumentation. It is equipped with a low power operational amplifier, so that the saturated operating voltage value is adjustable. The TO-92S RoHS package also has a wide operating temperature range from -40 to +125 degrees Celsius and works at a wide range of frequencies from DC to more than 10 kHz.
