Snap Action, Limit Switches

21CX14C is an electro-mechanical device widely used for sensing the presence or absence of objects, position of objects, over-travel, and for counting operations. It is used extensively in industrial applications, such as the control of conveyors, packaging machines, assembly lines, robotics, and other automated process control systems. The device contains two sets of contacts – a normally closed (N/C) contact and a normally open (N/O) contact. The device has two main functions: it can be used to detect a change in the environment or to act as a switch, controlling a circuit.

Application Field

One of the most common applications of 21CX14C is in motor feedback switches. In this type of application, the N/C contacts are used to detect the presence of the motor and the N/O contacts to control the motor. This method is often used for switching current in motors, to prevent over-stressing of the motor and its associated mechanical parts. 21CX14C devices are also used in applications such as automated door openers, window systems, and other similar types of automated systems.

In addition to its use in motor feedback switches and automated systems, 21CX14C can also be used in a variety of other applications. For example, it can be used to detect the presence of objects in packaging lines or to detect the position of objects on conveyor belts. It can also be used to detect over-travel in a system, and can be used as a limit switch to protect a machine from overload or damage. In addition, 21CX14C can also be used in applications such as machine tooling and two-hand control systems.

Working Principle

The working principle of 21CX14C is based on the concept of a switch. In this type of device, the N/C contacts are used to detect the presence of an object, and the N/O contacts are used to control the current in the circuit. When an object is placed in the device’s range, the N/C contacts close and the N/O contacts open, allowing the current to flow through the circuit. Similarly, when the object is removed from the range, the N/C contacts open and the N/O contacts close, stopping the current from flowing through the circuit.

The N/C contacts also have a “snap-action” feature which enables them to detect small changes in the environment. When a vibration or other small adjustment occurs, the N/C contacts can detect the change and respond by either opening or closing the circuit. This allows the 21CX14C device to detect small changes in the environment and respond accordingly.

Conclusion

The 21CX14C electro-mechanical device is widely used for sensing the presence or absence of objects, positions of objects, over-travel, and for counting operations. This device can be used in applications such as motor feedback switches, automated door openers, window systems, packaging lines, conveyor belts, over-travel, machine tooling, and two-hand control systems. The working principle of this device is based on the concept of a switch, in which the N/C contacts are used to detect the presence of an object and the N/O contacts are used to control the current in the circuit. The device also features a snap-action feature which allows it to detect small changes in the environment.
