ER6022-021ML

Snap action, limit switches are commonly used to control motion or transfer electric signals. The ER6022-021ML is a thermal type snap action limit switch that is used mainly to detect position and provide switch actuation signals. It is a cost-effective snap action switch that is designed to improve the efficiency of automated machine, electric unit, and other industrial system applications.

The ER6022-021ML limit switch consists of a metal housing, a dust cover, a helical contact mechanism, mounting screws, a wiring-side terminal, and a black plastic cap. This switch is sensitive to the temperature of its internal environment thanks to two thermistor elements. Its design features high repeatability, long life expectancy and reliable switching performance.

The ER6022-021ML switch has two basic working principles. “Thermally-actuated” switches are actuated either through the movement of the internal contact parts, when the temperature of the switch is increased due to its internal environment, or through the compression and extension of a thermally expansible tube.

The second principle at work is often called the “Non-actuated” switch. This type of switch is actuated either through the force of the external peripherals components, or through the use of a mechanical actuator in a manually actuated switch.

The ER6022-021ML thermal limit switch offers a number of advantages in a wide range of applications, such as electric motor control, HVAC system control, home appliances, industrial production control, robotics control, automotive industry, and medical device control.

The ER6022-021ML has a wide variety of applications for which it is used. One broad application is for general machine safety, through a safety circuit which controls door or cover locks. In the case of industrial production control, it can be used to cut off the electric circuit in the event of an overload. It can also be used in electric motors for accurate positioning in machinery and mechanical fixtures. In the automotive industry, it can be used in automobile engines to detect overheating and alert the engine to shut down. Additionally, due to the thermal action of the switch, it can also be used in the detection of thermal signals, such as those emitted by a heating element or a temperature sensor, thus allowing further control and feedback of automated processes.

The ER6022-021ML will offer reliable switching performance to its users and with its two thermistor elements, its design features high repeatability, long life expectancy and reliable switching performance. In addition, it is cost-effective and can be used in a variety of applications.
