Snap Action, Limit Switches

Snap Action, Limit Switches are electromechanical devices used to sense the position of machines, measure pressure, and control the flow of electricity. Their purpose is to detect the presence of objects, detect when limits are reached, and activate switches to turn on or off various devices.

12SE2 Application Field and Working Principle

The 12SE2 Limit Switch is commonly used in a wide range of applications in industrial automation and control systems. These include moving machine parts, determining material presence, and measuring pressure. The 12SE2 switch operates by using a snap contact, which is a spring-loaded, metal contact arm. When an object or pressure is applied to the switch, the contact arm is pushed against its spring, which causes the switch to open and close. This opening and closing generates an electric signal, which is then used to control the process or device. The 12SE2 switch has two sets of contacts: normally open and normally closed. The normally open contact is open until the switch is activated, and the normally closed contact is closed until the switch is activated.

Some of the features that differentiate the 12SE2 Limit Switch from other limit switches are its precision, durability, and reliability. It is designed for accurate repeatability and is capable of detecting repeatable angular positions within 0.2 degrees. The 12SE2 switch is RoHS compliant and comes with two integral mounting ears to ensure an exact fit. It has an electrical life of up to 100,000 cycles, and is rated to operate up to 55 degrees Celsius and up to 250 volts of alternating current.

The 12SE2 Limit Switch is a versatile, reliable, and durable switch, making it an excellent choice for industrial automation and control systems. Its precision operation and electrical life make it a good choice for a wide range of applications. Its two integral mounting ears also make it easy to install and configure, and its RoHS compliance makes it environmentally friendly. When combined with an appropriate controller, the 12SE2 Limit Switch can provide reliable and accurate control.
