Snap Action, Limit Switches are an essential part of any system, meeting the demanding requirements of diverse industrial applications. The D4NS-3BF series, manufactured by OMRON, is a great example of those switches. It offers quick operation, consistent performance and reliable durability, along with a wide range of operating principles and options that provide customers with connectivity and continuity.

The D4NS-3BF series is for use in process and automation control machines, as well as for safety applications. It is notable for its slim body, with a recessed button, and for its low operating power rating and long electrical life, up to 100 million operations. The robust cylindrical body is made from resin and reinforced with glass fiber and incorporates a snap action mechanism for good operation with less deflection.

The operating principle of the D4NS-3BF series is based on the snap action mechanism, which ensures the switch is capable of responding quickly and precisely to given thresholds. The snap action makes the switch highly reliable, allowing it to operate with extremely low electrical power and minimal contact bounce. The snap action also contributes to the long durability of the switch, as it is robust enough to cope with high demand applications.

In order to maintain its reliable operation, the D4NS-3BF series switches are designed with two spring-loaded contacts, called "acts." These contacts are positioned opposite each other, and when the switch is activated, the act contracts, which shifts the switch from one position to the other. Depending on the application and the sensor used, these contacts can be electrically or magnetically operated. Once the switch is in its new position, the act returns to its original space, ensuring consistent performance over time.

The D4NS-3BF series offers a wide range of options to suit any application. It is available in four different activation styles (mechanical, capacitive, inductive and reed switch) as well as three contact forms (N/O, N/C, N/C-N/O). This allows customers to select the best option for their application. Moreover, the switch is capable of operating in a variety of temperatures, between -25°C to +85°C, making it suitable for a wide range of environments.

The D4NS-3BF series snap action, limit switches are an ideal choice for process and automation control machines, as well as for safety applications. It is highly reliable, offering a long electrical life and a wide operating temperature range. Furthermore, with its snap action mechanism, customers can benefit from its quick operation and consistent performance.
