SMB Straight Plugs for Flexible Cables Datasheet

Category: Connectors, Electronics, Radiall

Overview

The datasheet details SMB (Subminiature version B) straight plug connectors designed for flexible cables. It includes two main types of connectors – “Straight Plugs Crimp Type” and “Straight Plugs Clamp Type,” differentiating them by cable attachment method. The document provides specifications on mechanical dimensions, part numbers, assembly instructions, the finishing materials, and notes on certain features such as captive center contacts and crimping options.

Straight Plugs Crimp Type for Flexible Cables

These connectors utilize a full crimp or reverse crimping technique to secure the cable. They are offered in multiple configurations with variations in size and design, as illustrated by Fig: 1 and Fig: 2. Each connector variant is identified by a unique part number (e.g., R114 073 O00, R114 073 134*0, etc.), which corresponds to a specific set of dimensions and features. The datasheet specifies that gold and nickel finishes are available, with some designs including a captive center contact. Notably, details provided include hex and flat dimensions as well as overall length and width specifications. Full crimp versions highlight the inclusion of a captive center contact, while reverse crimping/full crimp options omit this feature.

Straight Plugs Clamp Type for Flexible Cables

Alternatively, the clamp type connectors exhibit a design optimized for easy cable attachment via a conical braid clamp. Similarly, each configuration is associated with unique part numbers (e.g., R114 003 O00, R114 003 020*0, etc.) and selectable finishes in gold or nickel. These connectors also include a captive center contact and accommodate a variety of cable types, including RG180 upon request. The clamping mechanism ensures a robust and secure cable connection and is illustrated by additional figures not included on the first two pages of the datasheet.

Additional Information

Both types of connectors are designed to comply with the SMB interface standard, which assures compatibility and performance across a range of applications. The datasheet highlights the presence of captive center contacts when applicable, indicating a feature that ensures the stability of the central conductor during mating and unmating cycles. Finish options indicate versatility in application requirements, with gold finishes often indicating better corrosion resistance and higher conductivity, while nickel finishes may be selected for cost-effectiveness or specific environmental conditions.

The note sections mention “full crimp,” “reverse crimping/full crimp,” and “conical braid clamp” as distinctive features of the connectors’ cable attachment methods, providing insights into their assembly and physical characteristics. Although detailed packaging information is absent from the first two pages, the datasheet does hint at the availability of packaging options by listing “packaging: unit” under the notes section.

Last but not least, the datasheet is marked with the manufacturer’s name, “RADIALL,” a possible indication of the brand’s reputation or quality assurance pertaining to the SMB straight plug connectors.
