3-Wire Hall Effect Speed Sensor with Square Wave Output

The SUCH 3-wire hall effect speed sensor detects rotating gear teeth and converts each tooth pass into a square wave pulse, generating a frequency signal proportional to rotational speed. With IP65 protection and an operating temperature range of -40°C to 85°C, it provides digital output with a 47±5% duty cycle across a frequency range of 0-20000Hz. It is commonly installed on flywheel housings, gearboxes, and hydraulic motors to provide speed signals for pulse-type speedometers, tachometers, and RPM monitoring systems.

Feature

• Outputs a 3-wire square wave across a 0-20000Hz frequency range, compatible with pulse-type speedometers, tachometers, and RPM monitoring systems.
• Operates on 8-32V DC, supporting standard 12V and 24V power systems used in industrial and vehicle applications.
• Senses gear teeth at a distance of up to 2mm, defining the installation gap required for proper mounting.
• Produces a high signal above 10V and a low signal below 0.7V with a 47±5% duty cycle, giving connected controllers clear voltage thresholds to distinguish signal states.
• Carries an IP65 rating, protecting against dust ingress and water jets in outdoor and exposed installation locations.
• Rated for continuous operation from -40°C to 85°C, suited to engine and machinery temperature conditions.
• Connects via three color-coded wires — red for power, blue for ground, and black for signal output — for straightforward installation.
