Lancer speed sensor

Types of Lancer Speed Sensor

A Lancer speed sensor detects wheel rotation and helps the vehicle's computer determine how fast it's moving. There are different types of Lancer speed sensors, and they include:

• Gear tooth:

  The gear tooth speed sensor uses a magnetic coil and a toothed gear wheel to measure speed. It generates an electrical signal when the gear passes by the sensor, with the magnetic field changing. The number of teeth on the gear determines the sensor's output signal shape.

• Hall effect:

  The Hall effect sensor utilizes the Hall effect phenomenon in semiconductors to measure speed. It produces a digital pulse train signal proportional to the gear's rotation speed past the sensor. More pulses per revolution or fewer teeth on the gear result in a lower output signal frequency.

• Inductive:

  Inductive speed sensors rely on electromagnetic induction to measure changes in magnetic fields caused by rotating elements. They convert mechanical motion into electrical signals, with varying induced currents representing different speeds or directions of movement.

• Resistive:

  Resistive speed sensors change resistance in response to mechanical motion. The varying resistance alters an electrical signal sent to other systems, indicating changes in speed or position. These sensors are simple yet effective for basic speed detection tasks.

• Capacitive:

  Capacitive speed sensors measure changes in capacitance related to the proximity or movement of adjacent objects. As elements move closer or farther apart, the varying capacitance alters the electrical signal, allowing detection and measurement of relative speed or position changes.

• Magnetoresistive:

  Magnetoresistive sensors utilize materials whose electrical resistance changes in magnetic fields. They detect speed by measuring the varying resistance resulting from the proximity of magnetic elements, enabling precise motion tracking in various applications.

• Optical:

  Optical speed sensors use light (infrared, laser, or visible) to detect changes in reflected or transmitted light patterns. These changes are processed to determine speed or position, leveraging the principles of optics and light interaction with moving elements.
