The 8AC27 snap action limit switch is widely used in a variety of applications and can be found in industrial, commercial, and many residential settings. The 8AC27 is a type of limit switch designed to quickly break an electrical circuit when a specified limit is reached. The 8AC27 is an ideal choice for use in automation systems where a rapid and accurate response is required.

A limit switch works by sensing a physical change in the environment, either through the operation of a lever or roller, or by detecting a change in the ambient temperature or humidity. When the limit is reached, the switch contacts open, thus completing the circuit and causing a signal to be sent to the control system. The 8AC27 is capable of detecting changes in the environment up to 30 amperes, and accurate to 1/10th of an Amp.

The 8AC27 is most often employed in industrial applications, such as controlling motor starters, conveyor systems, and hydraulic systems. For example, in a conveyor system, the 8AC27 may be used to detect when a product has reached the end of the line, or if the conveyor becomes overloaded. Similarly, in a hydraulic system, the 8AC27 could be used to detect when a system reaches a certain pressure. The 8AC27 can also be used in commercial applications such as sensing falls in personnel on-site or watching access doors.

The 8AC27 limit switch features a specially designed actuator that allows it to sense and accurately detect changes in the environment without additional contact or wiring adjustments. This makes the 8AC27 very reliable and easy to install. The 8AC27 limit switch is also designed with a heat resistant case, making it well suited for use in high temperature applications. The 8AC27 is also capable of operating at low temperatures, making it suitable for use in cold storage areas. The 8AC27 comes standard with a single pole double throw (SPDT) contact arrangement.

The 8AC27 working principle is quite simple. A metal arm is attached to the switch body and when the appropriate limit is reached, the metal arm moves to make contact with the switch terminals and complete the electrical circuit. This movement of the metal arm can be initiated by the operation of a lever or roller, or by changes in the ambient conditions such as temperature or humidity. When the circuit is completed, a signal is sent to the control system and the operator is notified.

In summary, the 8AC27 limit switch is designed to rapidly and accurately respond to changes in the environment, thus providing a reliable, low maintenance solution for a variety of applications. The 8AC27 is an ideal solution for use in automation systems where a rapid and accurate response is required. With its robust design and negligible maintenance requirements, the 8AC27 is an excellent choice for many types of industrial and commercial applications.
