EX-AR800

Snap action, limit switches are vital components to the completion and success of large, complex electrical and mechanical systems. EX-AR800 is an advanced snap action, limit switch ideal for a wide array of applications. This switch offers precise, repeatable, and cut-off-ratcheting actions with high sensitivity and fast response time, securing a long trouble-free life. In this article, we\'ll discuss the applications and principles of this powerful device.

Application Field

EX-AR800 is an efficient, reliable switch for all types of control systems and industrial applications, from circuit protection to device control. It is widely used in high-precision, low-power applications such as:

• Hold-down or hold-off limit switches for actuators, slides, and cylinders
• Limit and over travel switches
• Position detection and reference setting switches
• Level and load sensing devices
• Level and bottom limit sensors
• Power switches
• Position switches
• Flow, leak, level, and pressure switches

EX-AR800 is also highly suitable for situations where fast response time, high performance, and precise control of a wide range of load sizes and operations is needed. Its design enables its use for controlling other devices, such as motors, pumps, or conveyors, without the need for additional components. Hard mounting further ensures an efficient, consistent operation in virtually any application.

Working Principle

The EX-AR800 switch is based upon a special type of "snap action" limit switch construction. It uses a pre-tensioned spring-loaded plunger arm, typically referred to as a throw arm, which contains a contact. The plunger arm positions the contacts in either the normally open or normally closed position. During operation, the throw arm moves rapidly in the opening or closing direction, corresponding the application.

In addition, the switch offers an adjustable repeatable contact point, meaning the contact point can be reset to maintain precise operation over multiple cycles. This feature allows for precise customization, making EX-AR800 ideal for applications where accuracy is essential. Furthermore, this switch also incorporates a ratchet mechanism, allowing for cut-off cycles, as well as precise monitoring of the number and length of cycles.

EX-AR800 is an excellent choice for applications where reliable, high-precision control is needed. Easy mounting and the reliable snap-action make this switch ideal for many industrial applications. Additionally, precise repeatability and ratchet mechanisms provide for precise customization and accurate time and count monitoring, further enhancing the performance advantages offered by this powerful device.
