Allegro Speed Sensors Overview

Allegro Speed Sensors provides high performance magnetic speed sensor solutions for automotive and industrial applications. Their products are widely used in camshafts, crankshafts, transmissions and wheel speed detection, and are characterised by high accuracy, high reliability and high interference immunity.

1. Camshaft Sensors

Allegro's camshaft sensor ICs use Hall effect technology to support true power-on state (TPOS) and non-TPOS engine regulator requirements. Its features include:

Single sensing Hall element design for easy installation without twisting.

Supports speed and direction detection for start-stop engine technology.

Highly programmable to adjust performance parameters to customer needs.

2. Crankshaft Sensor

Allegro's crankshaft sensor ICs are designed for high-precision RPM detection and are suitable for harsh automotive environments. Advantages include:

High vibration resistance and immunity to electromagnetic interference.

Supports dual or triple-wire output interfaces for compatibility with a wide range of system designs.

Integrated feedback bias magnet for ferrous metal target detection.

3. Transmission Sensors

Allegro's transmission sensor ICs provide optimised solutions for standard and hybrid transmission applications, with features including:

Support for high and low frequency operation and direction of rotation detection.

Suitable for vibration-resistant and high-speed rotation scenarios.

Available in two-wire power and three-wire open-drain output protocols to meet diverse needs.

4. Wheel Speed Sensors

Allegro's wheel speed sensors are designed for ABS systems and offer the following advantages:

Supports speed and direction detection for harsh automotive environments.

Advanced peak detection algorithms ensure stability in static modes and micro-oscillations.

Provide two-wire current output protocol for high compatibility.
