Unit Limit

SKU:U145

Description

The Unit Limit is a travel switch unit that provides a limit trigger signal to the MCU or other master peripherals by pulling the digital signal interface from 3.3V high to 0V low when the switch handle is closed by an external force. It is suitable for all kinds of moving machinery and equipment to control its stroke and carry out terminal limit protection.

FAQ

Question: What are the main types of limit sensors?

  • Limit sensors can be divided into two main types: contact and non-contact.

Contact limit sensors: Contact sensors use mechanical contacts or switches to detect the position of an object. When an object touches a contact, the sensor generates a corresponding signal. Non-contact limit sensor: Non-contact sensor uses optical, magnetic, ultrasonic and other technologies to detect the position of an object without the object in direct contact with the sensor.
