## Description

Digital panel tachometer for precise speed measurement in industrial applications, conveyor belts, motors and automation, clear display with 4 digits 0.56 inch and fast response, operates at 8-24V DC and measures 10-9999 RPM, includes NPN magnetic Hall probe at 5V and accepts other compatible NPN sensors for easy integration into control systems.
Digital panel tachometer, designed for precise measurement of rotational speed, using a Hall magnetic sensor with NPN output, making it suitable for industrial applications such as conveyor belts, electric motors and automated systems. The device offers fast response, good measurement stability and allows easy integration into various control systems.
The module comes with a Hall sensor, but you can also use another sensor (IR, Inductive, etc...) NPN operating at 5VDC and featuring Plus, GND and Signal connections. The signal is represented by a pulse triggered when a rotation is detected.
Specifications:
Supply voltage: 8 – 24V DC
Display type: Digital, 4 digits
Display size: 0.56 inch
Measurable RPM range: 10 – 9999 RPM
Sensor type: Hall magnetic with NPN output
Hall sensor operating voltage: 5VDC
Accuracy: ±0.1%
Panel cutout: 76 x 39.5mm
Use:
Power the tachometer using the dedicated terminals and connect the Hall sensor through the appropriate socket. Fix the magnet included in the package on the shaft or rotating element of the system, then position the sensor at an appropriate distance for detection. The tachometer will display the rotation speed in real time, allowing continuous monitoring of the system.
Attention! If the system rotation speed is below 10 RPM, the tachometer will display the message "LLLL" on the screen, and if it is above 9999, the tachometer will display the message "HHHH".
