Push-Pull Connector: The Ideal Solution for Reliable and Secure Connections

What is the Push-Pull Connector?

Push-pull connectors are circular connectors that provide an alternative to standard threaded or bayonet locking systems for butt connections. For this reason, the quick connect/disconnect connector is also one of the names. The connection is made by simply pushing the plug axially into the socket. The self-locking system allows complete docking by “pushing” to lock the connector firmly. A pull on the cable behind the plug activates the latching system and the connector will not accidentally detach. To detach the connector, “pull” gently on the plug’s jacket, and the latching system will release and allow the plug and receptacle to separate easily.

The Push-Pull Connector is a connection device for mission-critical environments. The purpose is to avoid accidental disconnection. Since 1957, this connector has been common in power distribution and data transmission areas. Thanks to its cylindrical design, the push-pull connector is one of the best choices for flexible use in environments with limited space. This connector offers durable, reliable, and long-lasting performance.

Advantages

Push-pull connectors can be used in any application where high reliability and top quality are required. These connectors offer contacts with long life and high mating cycles, are suitable for high vibration and shock environments, and provide strong EMC protection.

In the Lemo B, K, and S series connectors, the typical matte chrome plating provides a clean and aesthetically pleasing appearance to the connector, suitable for medical applications. In addition, these connectors have multiple keying options and color coding to help prevent the mismatching of similar connectors on the same panel.

Push-pull connectors feature a quick twist or finger pinch to release to reduce the risk of accidental disconnection. This release feature also increases the ease of use of the connector.

Push-pull connectors are available in various interface sizes and configurations, making them very flexible and adaptable to different applications. Therefore, when selecting push-pull connectors, people need to choose the right size and configuration to meet the requirements and get the best performance according to the application’s specific needs.

Application of Push-Pull Connectors

Push-pull connectors are used in various applications in demanding industrial, Harsh Environment Connectors, radio/communications, and medical/surgical fields. These connectors have become essential and critical in many applications with their safe and reliable data and signal transmission.

Push-pull connectors have the advantage of being simple to install yet extremely durable and resistant to the environment.This connector has high protection against dust, gas, mud, water, etc. Includes indoor and outdoor. As a result, push-pull connectors are highly resistant to the environment, including making connections underground and underwater.

Push-pull connectors are also the perfect connector choice for critical medical applications. Their high mix of plug and receptacle configurations and housing sizes make them available in many products to meet the medical needs of the field. This includes electrosurgical devices, pacemakers, hearing devices, ventilators, anesthesia and diagnostic monitors and analyzers, and dental equipment. These medical applications require highly stable, safe, and reliable connectors to ensure the effectiveness and safety of the devices.
