The 60-23p underspeed switch is a simple and universal monitoring device for shaft speed and other rotating devices with low cost and high reliability. The underspeed switch can be used to detect slippage or overspeed of the belt.

The underspeed switch is initially placed in a weatherproof, sealed, corrosion-resistant enclosure to allow exposure to harsh conditions.

Device description

Non-contact proximity to detector, long life, low maintenance cost

Two bolts are fixed to ensure simple installation

Integrated structure, centralized control device, simple setup or troubleshooting

No moving parts, no wear, long safety life

Alarm/delay - when the rotating device has not reached the working speed during the starting process, the alarm will be delayed for 10 seconds

Delay alarm - alarms when the speed drops below the adjustable setting point
