Snap Action, Limit Switches are vital in automation applications as they are used to sense the presence of objects usually on the assembly line. This can be seen in many industries such as automotive, medical, consumer and industrial to name a few. They are usually the last resort for stopping the movement of the equipment involved and are often the first thing to ignore when it comes to maintenance and upkeep of the system.
The 311SM2-H4 is a compact, universal mini-style limit switch with a trapezoidal plunger. It is constructed with a die-cast metal body and a plunger, which is adjustable and hermetically sealed with a silicone potting. The body is also resistant to high temperatures, corrosion and shock, making it suitable for many industries, including aerospace applications.
The 311SM2-H4 is usually used for detecting the presence of small objects that can be moved by a pneumatically or hydraulically operated actuating arm. When the object comes into contact with the arm, it pushes the plunger on the switch. This triggers the internal switch mechanism, which in turn, activates the electrical circuit and provides an indication when the object has been detected. With its die-cast metal body and hermetically sealed plunger, the 311SM2-H4 is able to withstand and operate reliably in harsh conditions. This makes it ideal for use in extreme environments, such as found in industrial plants.
The 311SM2-H4 is also easy to install, requiring only a few screws to secure it to the actuating arm. Once installed, the arm is adjusted to the desired length and the plunger can be adjusted to the specified length for the desired application. The 311SM2-H4 does not require the use of external power, such as a battery, to operate, which makes it suitable for use in portable systems.
In conclusion, the 311SM2-H4 is a high-performance mini-style limit switch for detecting the presence of small objects on the assembly line. With its die-cast metal body, hermetically sealed plunger and adjustable arm, it is perfect for extreme environments as well as portable systems. Its easy installation and maintenance make it one of the best options for quick and reliable detection of small objects.
