21SX39-T2

Snap Action, Limit Switches

The 21SX39-T2 snap action limit switch is a single-pole switch designed to provide reliable and precise electrical control. Its versatile design allows it to be used in a range of applications, such as security systems, industrial machinery, robotics, and automation, while providing a consistent level of reliable performance. The switch features a spring-loaded plunger that is activated when an object comes into contact with the switch. The plunger pushes or pulls the switch\'s contacts, which in turn causes the switch to close or open, thus controlling the circuit it\'s connected to.

The switch\'s design also features a wide range of operating temperatures, from -25°C to +85°C, making it suitable for many indoor and outdoor applications. The accuracy and reliability of the switch is further enhanced by its low contact resistance which is obtained through its gold-plated contacts. Additionally, the switch does not require any special maintenance and is designed to provide reliable and accurate operation even in the most rugged conditions.

The 21SX39-T2 switch is suitable for a variety of applications and can be used to control motors, lamps, and other electronic equipment such as solenoids and contactors. It can also be used in safety systems and security systems, such as access control systems, to provide an additional layer of safety. Additionally, the switch can be used in industrial machinery, robotic applications, and automation to control the speed, direction, and other movement of machinery.

The 21SX39-T2 switch is extremely reliable, with a high cycle life of up to one million operations. It is also designed for use in a wide range of voltage applications from 10 V to 415 V ac/dc. Additionally, the switch is UL, CSA, and EN approved to ensure safety of personnel and equipment.

The switch is relatively easy to install and its SPDT single-pole contacts make installation quick and reliable. Furthermore, the switch is designed with robust construction, which provides better performance and higher reliability in a variety of environments, even when exposed to shock, vibration, and abrasive dust.

In conclusion, the 21SX39-T2 snap action limit switch is a cost-effective solution for a wide range of applications. It features a reliable design, rugged construction, and low contact resistance for high accuracy and system safety. Additionally, it provides a high cycle life and is resistant to shock, vibration, and abrasive dust.
