A-20GV21-C-K Snap Action, Limit Switches

A-20GV21-C-K Snap Action, Limit Switches are designed for applications where physical access and contact are limited. This makes them ideal for industrial machinery and equipment that rely on safety systems and absolute precision for operation. The A-20GV21-C-K is a miniature, high-amsensor switch that is designed to detect the presence or position of an object, typically within a limited range of travel. These limit switches can work up to a tolerance of 0.1mm or 0.001” and are accurate up to 2 microns at full travel.

The components that form the A-20GV21-C-K Snap Action, Limit Switch are a movable contact, a stationary contact, a switch actuator, a reset button, and a switch base housing. The movable contact is made of hardened stainless steel, while the stationary contact is a brass-plated contact. The switch actuator is also stainless steel and is driven by a spring mechanism. This spring mechanism is tensioned by a reset button which causes the actuator to move and make contact with the stationary contact when the actuator is moved past the “click” point and spring release. Once the actuator moves past the switch base housing, this closes and opens the switch to complete a circuit.

The A-20GV21-C-K Snap Action, Limit Switch also has a number of advantages, such as: being designed for use in high vibration environments; being extremely sensitive and accurate; having a low power consumption; and providing a low cost solution for simple single function switching. The switch is also UL rated, making it safe to use in almost any application. Additionally, the switch can be used with a variety of standard and custom actuators to meet a variety of needs.

One of the most common applications for the A-20GV21-C-K Snap Action Limit Switch is detection of a range/limits on large or complex machines and industrial machinery. For example, this switch can be used to detect the position of a robot arm or limit the movement of a lathe. Additionally, it can be used to detect the motion of slides, indexers, or automated equipment. The switch is also used in many safety systems, where it can be used to detect presence or absence of safety guards or limit switches to prevent a machine from starting or operating if any of the safety guards are removed.

Additionally, the A-20GV21-C-K Snap Action Limit Switch can be used in automation, industrial and medical applications. Automation applications include conveyor applications, machine tool applications, packaging machinery, medical equipment and assembly lines. The switch is also used in medical applications such as medical gas analysis, medical device testing, and oxygen analysis.

In conclusion, the A-20GV21-C-K Snap Action, Limit Switches are an excellent solution for applications where physical access and contact are limited. They are accurate and reliable, and can be used with a variety of actuators and standard and custom applications. With a low power consumption and a UL rating, they are an ideal choice for a variety of applications.
