Snap action limit switches are a special type of limit switch that are characterized by their remarkable quick response and holding capacity. The EX-AR20 is a type of snap action limit switch specially designed for harsh environments such as high-temperature production lines or hazardous areas. It has an operating temperature range of -20 to +120 degrees Celsius and a compact size that makes it ideal for tight spaces. The unit also features an integrated dust cover and increased shock resistance compared to traditional limit switches.

Snap action limit switches are typically used in motion control and automation applications where precise, fast switching is required. The EX-AR20 is ideal for applications where the environment can quickly change and/or the switch must be able to withstand a high degree of mechanical stress. These applications include high-frequency motors, conveyor belts, position sensors, and more. Due to the EX-AR20’s superior accuracy and durability, it can also be used in safety systems in critical applications where reliable operation is a must.

The working principle of the EX-AR20 relies on the concept of mechanical stress. The switch is mounted on a spring-loaded plunger. When the plunger is pushed, the spring stretches, increasing the force put on the switch. When the plunger is released, the spring contracts, pushing the switch back to its original position. This snap action produces a momentary pulse which is detected by the unit’s internal circuitry. The signal is then passed on to the controller or another device, triggering whatever action is necessary. This rapid response makes snap action limit switches particularly suitable for motion control applications.

In addition to a high degree of accuracy and speed, the EX-AR20 also features a large contact gap which helps to ensure reliable switching in hazardous environments. The switch also has a flat constructions and narrow profile, making it ideal for applications where size and weight are a factor. The EX-AR20 is also very easy to install, with no special tools or training required. Finally, the switch is extremely energy efficient, consuming a minimal amount of power.

The EX-AR20 snap action limit switch is a highly reliable and rugged device that is ideal for a wide range of motion control and automation applications. Its spring-loaded plunger provides a quick and accurate response, while its large contact gap, narrow profile, and low power consumption make it perfect for harsh environments. When combined with its easy installation and maintenance free operation, the EX-AR20 is an unbeatable choice for any motion control or automation project.
