A Helpful Guide in Understanding Push-Pull Connectors

Push-Pull Connectors

Connectors come in various shapes and sizes with each having distinct features and uses. 

Today, we’ll talk about push-pull connectors, the connectors are very obvious to find in the electronics markets These connectors are placed inside the circular connectors and are designed with a locking mechanism, which will position the connectors automatically when inserted. The only way to disconnect them is when the connector’s casing is backwardly pushed. 

The entire push-pull connectors setup provides secure and safe mating mechanics when it comes to crucial and complex applications. Let’s get to understand more what push-pull connectors really are and how they can be helpful to certain applications. 

Cycle Rate 

Push-pull connectors are mostly applicable to medical equipment and devices, both vehicles and intel devices for military use, and any application where sudden or accidental cut off can lead to tragedy. They are also used on machines that need connectors to improve their lifespan. 

Plastic push-pulls are proven to have at 2,000 cycles while the metal ones have 5,000 cycles. Cycle rates are the mating and unmating cycles of push-pull connectors. In every cycle rate, it will take milli-ohms of contact resistance increased. Contact resistance is the resistance to flow due to surface condition when push-pull connectors are contacting one another. 

Also, most push-pull connectors are lightweight and made of metal or plastic, thus creating a greater cycle rate and lesser resistance. 

Locking Mechanism 

The locking mechanism of push-pull connectors provides a clean, seamless look on equipment. It saves a lot of space since you can only grip the shell to disconnect or connect, without even twisting the entire connector. You can also mount numerous connectors together closely without any heavy tools to complete the whole installation. 

The connector can only be disconnected by pulling back the body from the external sleeve. The locking process is done by pushing the plug, which prevents possible disconnection done accidentally. The benefit of this locking mechanism is that push-pull connectors can be connected or disconnected without using heavy or complicated devices. 

The Design 

Most push-pull connectors used in the industrial field are circular, although some are also rectangular and square in style. Circular designed connectors support more complicated cable assemblies. Moreover, this has been a cost-effective mechanic when it comes to machining bar stock, considering the high demand for connector tolerance. 

The internal parts are mostly circular, too. This includes spacers, contacts, insulators, collet nuts, and collets. Push-pull connectors in rectangular design have latched on each side, however, they also use similar internal components to that of circular connectors. 

Data Transmission 

Another amazing feature of push-pull connectors is their ability to transfer data, signal, fiber optics, signal, or pneumatic media. Push-pull connectors enable users to mix two or more elements into one cable. This simplifies the usage and helps organize the cabling system better to make it foolproof for the users. 

Circular Connectors

Generally, the majority of push-pull connectors are made for circular cable applications. Some are designed as disposable materials that are used for cleanliness and order. It can either be intended for intense applications in an outdoor setting or indoor setting. Major features include water-resistant ratings for submersion in water (entirely), vibration, shock resistance, dust-proof, the list goes on. 

Since circular push-pull connectors are made for circular cable types, it is vital in the aspect of cable design to put ideal fillers, most particularly in an application that requires environmental covering. 


  • Equipment protection — push-pull connectors are water-proof, highly rated for IP68 standard in terms of unmated or mated condition. Will give protection to any device from liquid or fluid projection. 
  • Uniquely calibrated — For users, understanding that push-pull connectors can be calibrated uniquely is important. This process allows the matched pair to control. Typical or reverse gender (male and female headers) contacts can be utilized in their blueprinting, depending on which part of the cable the power is coming out from. In order to maintain 360° EMI protection and continuity, the shield is applied through the shell in metal connectors. 
  • Sterilization — can withstand steam sterilization through an autoclave, with gravity and pre-vacuum process for displacement. This is intended for connectors used in the medical setting. Connectors under this application are rated 200 per autoclave cycles (134°C). 
  • Safe and convenient — safe and easy since it only needs two fingers to unlock or lock connectors securely with a tangible and audible indicator. They are capable of more than 2,000 times mating, and numerous keying. Color variations are available too to prevent from accidental errors in the mating system. 
  • Modern layout — push-pull connectors are designed to be really aesthetic. They are attractive and are and pleasing to look at. They can fit all medical designs too. 


Push-pull connectors are designed to suffice the needs of certain user application, especially in the medical field. They are convenient to use as they are built with a simple structure. The push-pull connector system is flexible and aesthetically pleasing. They can withstand harsh outdoor and indoor conditions making them feasible to users just like with sturdy LED aluminum profile.
