Hall Effect Gear Tooth Speed Sensor for Elevator Motor

A hall effect gear tooth speed sensor is a non-contact device that measures rotational speed by detecting magnetic field changes as gear teeth pass the sensing element, converting this motion into a stable square wave output signal. The SUCH sensor applies this principle with a design that eliminates physical contact with the gear, reducing mechanical wear and removing the need for additional target wheels or couplings during installation. It is used for gearbox speed measurement and elevator motor speed monitoring and control systems, providing continuous speed feedback for motion control applications.

Feature

• Hall Effect, Non-Contact Sensing — Detects speed by sensing magnetic field changes at the gear tooth tips and roots, with no physical contact or wear on rotating parts
• Direct Gear-Tooth Compatibility — Mounts directly opposite an existing gear, removing the need for a separate encoder wheel or additional mechanical adapter
• Square Wave Output — Delivers a square wave pulse signal for integration with motor controllers, PLCs, and drive systems
• Continuous Duty Operation — Designed for continuous operation in gearbox and elevator machine room environments, providing ongoing speed feedback
• Compact Housing — Sized for installation in confined mechanical compartments
