For what type of applications should I select the ODU MINI-SNAP® connectors?

ODU MINI‐SNAP® is the ideal self‐locking circular connector used for transmitting power, signals, data or other media. This circular connector has a robust metal housing. The Push‐Pull locking ensures that the connection never releases until you want it to: once mated, the ODU MINI‐SNAP® locks itself into the receptacle. It can no longer be unmated by just pulling the cable. The plug can however easily be mated from the receptacle when the outer sleeve is pulled back.

The ODU MINI‐SNAP® is available in a wide range of sizes and designs. You can choose from three basic keyings. We also offer a complete solution: Connector plus cable. ODU has exactly the right cable assembly, whether as a standard version or customized to meet specific requirements. We design, manufacture and assemble these products in‐house.

Where are the ODU MINI-SNAP® connectors normally used?

Because of their versatility and autoclavability, the ODU MINI‐SNAP® connectors are used in a wide range of applications such as medical technology, test & measurement technology, military, security and communications, industrial electronics and energy.

What exactly is a mating cycle and how often can you connect and disconnect an ODU MINI-SNAP® connector?

The mechanical actuation of connectors and plug devices via push and pull action is commonly referred to as a mating cycle. A mating cycle consists of one insertion and withdrawal action. ODU’s standard value for the ODU MINI‐SNAP® series is 5,000 mating cycles.

What are the main differences between the various ODU MINI-SNAP® Series of connectors?

The ODU MINI‐SNAP® circular metal connector portfolio includes various series: L, K, B, F, which differ from each other depending on the physical locking method of the push‐pull mechanism and the keying or coding for correct mating of the plug with the receptacle. Environmental requirements also play an important role when selecting the correct ODU MINI‐SNAP® connector. For more information see the table detailing the technical data.

How do I compare and choose the correct ODU MINI-SNAP® Series or style for my application?

The best way to select the correct connector for your application is to try a free sample. The easiest way to get a free sample is to visit our website and enter your requirements into the Product Finder. Alternatively, you can contact your local point of sale or ask for assistance with the selection process. The technical data table gives an overview of the main connector features of the L-, K- & B-Series. These connectors have a pin and groove keying.

What does “keying” mean?

Keying represents connector alignment with the receptacle or plug. There are up to 6 sizes (outer diameter 6.4 mm to 25 mm), 3 termination types (crimp, solder or PCB) and a great variety of various contact inserts to choose from (number of contacts 2 to 40 contacts, mixed inserts). Please note the differences in IP-ratings, no. of contacts, cable diameters, and available sizes, etc. For more information, see the table detailing the technical data.

What about the F-Series?

The F‐Series makes use of an alternative keying method: the half‐shell located inside the connector and the matching receptacle. A variety of matching half‐shells are available depending on the connector size. Full details of all ODU MINI-SNAP® connectors are available in the technical catalog.
