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.
Key Features
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
