AVL3825613-A

Snap Action, Limit Switches

AVL3825613-A is a typical snap action, limit switch, which is specifically designed for meeting the increasingly high-end market standard. It is widely used in various industrial automation or electromechanical applications such as machine tools, food processing, automation systems and HVAC (Heating, Ventilation and Air Conditioning) systems.

Applications

Typically AVL3825613-A has a variety of enhanced features, including a long durability and excellent environmental performance. It is must for many industrial applications, due to its reliable contact, long life and good electrical switching continuity. Its most common applications include:

• Cable Pull Switches: Used to detect pullout of the cable, primarily in applications such as the equipment lift and medical bed.
• Automatic Door Openers: Used to an electromagnetic contact which detect the presence of a person and triggers an automatic door opener.
• Industrial Robot Arms: Used in robot arms, actuators and shafts to detect the position of the robot arm and to switch off the motor if the arm is in the wrong position.
• Valve Position Sensors: Used to detect the open/close status of a valve.
• Encoder Switches: Used to detect the position of an encoder wheel for accurate positioning.
• Motion Control Systems: Used to detect the angle of rotation or linear movement for various motion control systems.

Design and Working Principle

AVL3825613-A is a high-end snap action, limit switch which utilises a specially designed mechanism comprising of a carbon slider and an actuator arm. It is designed to offer reliable, repeatable operation and a long service life while operating in the rugged industrial environment. The contact mechanism comprises two normally closed contacts connected in series, and a normally open contact connected parallel. The actuator arm and the slider are connected at one end and are operated by a cam or levering action. When an actuating force is applied to the switch, the actuator arm is pushed down and the slider is pulled against the operating force of a spring, thus making the normally closed contacts open and the normally open contact closed.

Upon release of the actuating force, the spring exerts force to the actuator arm and the contacts revert to its original states. The switch can be adjusted to open and close on specific angles so that it can selectively indicate the opening or closing of mechanical devices. When correctly setup, it provides accurate switching and consistent operation.

AVL3825613-A is highly recommended due to its reliability and long operational life. The switch is designed to withstand a wide range of temperatures, humidity and vibrations, providing more reliable and safer performance comparison to other similar switches. It is highly recommended for any industry requiring reliable switching, long operational life and superior performance.
