描述 Description

The MA3055S10 is a high output VRS magnetic Speed Sensor, designed for use in applications where the sensor is exposed to temperatures up to 260°C (450°F). Sealed front-end version is available for applications where the sensor is exposed to fluids, lubricants or adverse environmental conditions. The passive VRS (Variable Reluctance Speed) magnetic speed sensor is simple, rugged devices that do not require an external voltage source for operation. A permanent magnet in the sensor establishes a fixed magnetic field. The approach and passing of a ferrous metal target near the sensor's pole piece (sensing area) changes the flux of the magnetic field, dynamically changing its strength. This change in magnetic field strength induces a current into a coil winding, which is attached to the output terminals.
