21EN51-S is a two-piece adjustable snap action switch that is used to control the safe operation of industrial machinery and equipment. It offers a wide range of operating temperatures, adjustable contacts, and a highly reliable design. It has a low power draw and is capable of monitoring high power loads. 21EN51-S is commonly used in safety applications in hazardous atmospheres, chemical, oil and gas industries, and on many machine tools. The 21EN51-S can detect the limit switch position and provide the required signal to the control system.The 21EN51-S operates using a snap action mechanism that comprises of a contact head and lever. When the actuator reaches the end of its travel, the lever trips against the contact head, which then causes the contacts to open or close. This snap action provides reliable and repeatable switching. The 21EN51-S is designed to be highly adjustable, with adjustable contact settings and operating temperature ranges. It features an extremely robust design, with a tight seal and a solid mechanical construction. The 21EN51-S has a wide operating temperature range of up to 545°F, and a contact setting tolerance of less than 0.011”. This allows it to be used in a wide range of applications and environments.The 21EN51-S is also designed to be easy to install and maintain. It includes a rear base mount for mounting on a variety of surfaces. The contacts are made from stainless steel and are replaceable for easy maintenance. It is also designed to be vibration-resistant, which allows it to be used in harsh and demanding environments. The 21EN51-S is used in industrial control systems, process control systems, power distribution systems, and monitoring systems in a wide range of industries. It is ideal for applications that require contact settings, flexible operating temperatures, and highly reliable switching. The 21EN51-S is an ideal solution for applications requiring reliable and repeatable switching, and is designed to offer maximum protection and peace of mind.
