This switch is an economic, reliable, simple and universal monitoring device for shaft speed and other rotating devices. When the current speed signal is detected to be lower or higher than the normal speed range, the switch outputs two sets of switch signals for alarm or shutdown.No moving parts, no wear, long safety life, integrated structure, centralized control device, simple setting or fault maintenance.The shell adopts waterproof and dustproof design with two bolts to fix the shell, which can be directly installed in harsh environment.

I. technical parameters:

Power supply voltage: AC220V detection range: 0.5m/s ~ 9.99m/s

Pulse rate: 6 ~ 120Hz speed: 0 ~ 999 RPM

Boot delay: 10 second switch and target distance: 10 ~ 20mm

Number of switches: 1 set of normally open and 1 set of normally closed

Contact capacity: 24 ~ 380V AC/DC current 1A

Detection indicator: when the speed range is within the set range, relay output, LED luminescence can help detect the sensor or check the wiring failure

Non-contact underspeed switch is a simple and universal detection device for low cost, high reliability, speed of shaft and other rotating devices. It is placed in a weatherproof sealed and corrosion-resistant enclosure to allow exposure to harsh environments.

Ii. Advantages:

1) non-contact proximity detector, long service life and low maintenance cost;

2) fix the bolts and ensure simple installation;

3) simple integrated structure, centralized control device, setting or fault maintenance;

4) no moving parts, no wear and long safety life
