Zhong He SMCB-02 Magnetic Speed Sensor | Dual Channel Tachometer Probe

The Zhong He SMCB-02 Magnetic Speed Sensor is a high-reliability dual channel tachometer probe designed for precise rotational speed measurement and direction detection of rotating machinery. Utilizing SMR sensitive components, this passive magnetic sensor is triggered by ferrous magnetic conductors and integrates internal amplification and shaping circuits to deliver stable square wave signals suitable for long-distance transmission in harsh industrial environments.

• Dual channel design outputs two square wave signals with 90° phase difference
• Forms equipment operation direction monitoring system with reverse speed meters
• Excellent measurement performance with response frequency range of 0.3Hz~20KHz
• Measurement accuracy of ±1 pulse with detection distance of 0.5~4mm
• Working voltage: 5~24V DC with stable square wave output
• Polarity and short-circuit protection with IP65 protection rating
• Operates in temperatures from -25°C to +80°C with ≤95% RH humidity
• M16×1 threaded design for easy installation with adjustable mounting gap

Widely applied in machinery, metallurgy, petrochemical, automotive, and power industries. Ideal for measuring speed and angular displacement of motors, turbines, gears, and other rotating components. Provides reliable, accurate speed and direction data to prevent equipment damage caused by abnormal rotation and ensure efficient, safe operation of industrial systems.
