Unit Limit
Description
Unit Limit is a limit switch unit. When the switch lever is pressed by an external force, the digital signal interface of the switch unit will pull down from a 3.3V high level to a 0V low level, providing a limit trigger signal to an MCU or other main control peripherals. It is suitable for various types of mechanical equipment to control their travel and provide terminal limit protection.
