Product Overview
MYDH-Ⅲ slip switch
It is used to detect the slip between the belt conveyor and the active roller during operation to prevent the malignant accidents caused by the slip. The detector can also be used for interlocking start and stop of multiple belt conveyors, and low-speed brake protection.When the speed detector is working, the trolley is driven by the tape to make the trolley reflect the actual speed of the tape. The trolley drives the transmission shaft in the detector to make the internal relay of the product work. The relay works mainly by cutting the photoelectric signal by the wheel. The built-in fixed value and the actual value are compared to generate the on-off signal to complete the detection of belt speed. If the belt speed is not synchronized with the main drum speed and drops to 20-30 of the normal belt speed, the contact on-off signal changes. Re-output a set of signals to the control room to warn the staff that the tape has been severely slipping.

Q1:Difference between normally closed and normally open tilt switch? A1:Normally closed is to switch on and off after tilting in vertical state, while normally open is to switch on after switching off tilt in vertical state.   Q2:The difference between manual reset and automatic reset? A2:Manual reset is to pull the rope switch action to continue to hold after release, need to reset device to restore, automatic reset is pull rope switch action release switch recovery.   Q3:Difference between unidirectional pulling rope and bidirectional pulling rope? A3:One way is to install the pull rope from one side of the switch, and the other way is to install the pull rope from both sides of the switch.   Q4:Is the action force of pull rope switch adjustable? A4:The required action force can be informed in advance and can be customized according to the requirements.
