• Robotics and Material Handling
  

The VB-2121 is specifically designed for applications that require control and sensing capabilities with high accuracy and reliability. It has multiple contact ratings, allowing for a versatile functionality. It is designed for both surface and sub-surface mounting, which makes it ideal for applications where limited space is a factor.

Working Principle of VB-2121

This snap action, limit switch uses a pair of contacts, one normally open and the other normally closed, that are actuated by a plunger attached to a stem. When the stem is pushed or pulled, the plunger is activated or released and the contacts open or close. The VB-2121 is a mechanically-operated limit switch which offers precise control accuracy with long life. The snap-action design of the switch ensures that precise operations are carried out in a reliable manner.

The VB-2121 has a rotatable shaft, which allows the actuator to be adjusted to different angles, making the switch suitable for a variety of applications. The maximum switching power is 5A/250VAC and a maximum current of 3A/2A/1A can be used at 250VAC/125VAC/30VAC. This snap-action limit switch is designed to resist shock and vibration. Its small size, light weight and superior performance also make it suitable for use in tight spaces.

The VB-2121 snap-action limit switch is an ideal solution for applications requiring high reliability, accuracy and long life. This versatile switc is suitable for a variety of applications, providing precise control and sensing capabilities. Its economical construction and adjustable shaft make it an ideal choice for applications where limited space is a factor.
