The Bendix 4000191-8502 sensor is a three-wire Hall Effect sensor. It generates a voltage output in response to the presence and direction of a magnetic field. The sensor's housing is made of high-strength, corrosion-resistant materials, ensuring durability and longevity, even in harsh automotive environments.
The sensor's active element is a Hall Element, which consists of a thin semiconductor layer sandwiched between two permanent magnets. When the rotor passes by the sensor, it generates a magnetic field that interacts with the Hall Element. This interaction causes a voltage to be generated, which can be measured and processed by the vehicle's electronic control unit (ECU).
The Bendix 4000191-8502 sensor comes with a built-in temperature compensation feature, ensuring accurate and reliable output even under varying temperature conditions. It has a wide operating temperature range of -40 C to 125 C (-40 F to 257 F), making it suitable for use in various automotive applications.
The sensor's output is a square wave signal, with a typical frequency of 125 kHz. The sensor's resistance is 12 ohms, and it has a maximum power consumption of 1.2 watts. The sensor's dimensions are 33.4mm x 21.2mm x 11.8mm (1.31 inches x 0.83 inches x 0.46 inches), making it a compact and efficient solution for rotor position sensing.
In summary, the Bendix 4000191-8502 Magnetic Pickup Sensor is a reliable and robust solution for automotive applications that require accurate and real-time monitoring of rotor position and speed. Its Hall Effect technology, temperature compensation feature, and compact size make it an ideal choice for various engine management and anti-lock braking systems.
