What precautions should be taken during installation?

Ensure no metal objects other than the sensing surface exist on the side of the driven pulley to prevent false pulse signals.

What is the detection distance?

The maximum detection distance (Max.Sn) is 20mm.

What is the rotation speed range?

The device detects rotation speeds between 30 and 100 Rev/min.

Product Q&A

Q:How does the under-speed slip switch work?

It detects rotational speed without contact. When the speed drops below the preset value, the control circuit triggers a switch signal to stop the machine.

Q:What is the installation requirement for the inductive surface?

The driven wheel or shaft must be welded with an iron surface. The cross-section must be at least 50mm x 50mm, with a max distance of 25mm from the switch.

Q:Can the speed value be adjusted?

Yes, the speed value is adjustable. Press the SET key to show digital flashing, then use the key to adjust the slipping value before pressing SET again to confirm.

Q:What is the working voltage and contact capacity?

The working voltage is AC220V. The contact capacity is AC240V 3A with 1NO 1NC configuration.

Q:What is the start-up delay time?

The start-up delay is approximately 10 seconds.
