311SM2-H2

Snap Action, Limit Switches

A snap action limit switch is an electro-mechanical device that is used in many automated processes and machines to turn a signal on and off. The 311SM2-H2 is a type of mechanical limit switch, which uses a lever on a plunger to open and close a switch when something passes by it. It can be used in a wide range of applications including control panels, mines, and, most commonly, industrial safety systems.

The 311SM2-H2 has two basic components: the actuator, which detects the presence of an item, and the power unit, which supplies the electrical signals. The actuator consists of a plunger, a stem and lever, and an adjustable head, all of which support the switch. When an item passes by the head of the switch, the plunger is pushed in, causing the stem and lever to move and open or close the contacts. The power unit supplies the electrical signals to the switch, allowing it to open and close.

The 311SM2-H2 has several advantages over other types of limit switches. It offers fast response time, reliable operation, and it is extremely durable. It can be used in extreme temperatures, from -20°C to +50°C, and is designed to be immune to vibration and electrical interference. In addition, it has adjustable capabilities that allow it to be tailored to a wide range of items, including uneven surfaces. The adjusting head can be adjusted to cover any distance up to 150mm.

The 311SM2-H2 is most commonly used in industrial safety systems. It is used to detect objects that might be hazardous to people or machines, and trigger an alarm or shut down a process if they come too close. It can also be used to detect motion and movement, and is used in automated processes to initiate movement when an object passes. It is also used to detect the presence of items in packing systems, automatically count items or control packaging motors.

The 311SM2-H2 is a reliable and durable limit switch that can be used in a wide range of applications. It offers fast response time, reliable operation, and adjustable settings that make it easy to tailor to different items. Its most popular application is in industrial safety systems, where it can detect the presence of hazardous items and trigger shutdowns.
