When it comes to industrial automation, accurate and reliable operation is a must. That is why limit switches are so important in many industries, particularly in the control of machines and other processes. Snap action, limit switches are designed to do just that – they alert other components to the machine’s status and help ensure safe and precise operation. As such, one of the most popularly used limit switches is the 914CE3-KQ. This article dives into the application field and working principle of the 914CE3-KQ.

Application field of 914CE3-KQ

The 914CE3-KQ snap action, limit switch is ideal for a range of different applications. It is most commonly used in industrial applications, such as in material handling machines, moving assembly lines, conveyors and more. The switch is also used in more precise operations, such as detection in medical instruments, metalworking and other machine tool applications. Additionally, it can be used as a circuit interrupting switch in medical and optical equipment, computer components, electronic instruments, and more.

The 914CE3-KQ is also immensely popular in automotive and outdoor applications. It can be used to accurately monitor or detect objects in the running of large-scale automotives such as robot arms, transport lines, etc. As well, it is a great choice for outdoor use. The lower limits of the 914CE3-KQ are suitable for use in low-temperature environments and its robust enclosure effectively prevents contaminants from entering the interior lens, making it an ideal switch choice for off-road vehicles, construction machinery, and more.

Working principle of 914CE3-KQ

The 914CE3-KQ snap action, limit switch works by sensing the presence (or absence) of an object or composition. This is done using a contact arm that is mechanically linked to an actuator head. There are two different types of contact arms - normally open (NO) and normally closed (NC). The NO type of contact arm causes the circuit to be OFF unless an object is detected and the circuit is then turned ON. Conversely, the NC type causes the circuit to be ON until the object is detected and then the circuit is turned OFF.

The actuator head is used to move the contact arm, activating it when an object is detected. There are several different types of actuator heads available for the 914CE3-KQ, such as a plunger with either flat or round button, a roller plunger, a full travel lever, and a half travel lever. The plunger actuation mechanism is the most commonly used, as it creates a snap action, thus the limit switch’s name.

The snap action means that one moment the contact arm is OFF and the next moment it is ON. This is followed by an audible click as the contact arm moves, indicating that the switch has been activated. This makes it much easier to identify and diagnose a potential problem. In addition, the total reset force on the contact arm is adjustable, allowing the switch to be fine-tuned to different environmental conditions.

Conclusion

Overall, the 914CE3-KQ is a reliable and versatile snap action, limit switch. It is easy to use and adjust, which makes it suitable for a range of different applications, including industrial and automotive use. Its snap action contact arm and adjustable reset force guarantee accurate and reliable operation every time, ensuring a safe and precise operation for various types of machinery and equipment.
