Category: Connectors, Electronics, Radiall

Overview of the 1/3 R128.609.001 Series BMA Screw-On Female Receptacle

This datasheet provides technical information about the 1/3 R128.609.001 Series BMA screw-on female receptacle, which is a hermetic electrical component. Hermetic connectors are designed to ensure airtight sealing and are typically used in applications where leakage could be critical. This model includes a hexagonal section of 7.9 mm with flats and has overall dimensions with a maximum length of 70.5 mm and a diameter suitable for a panel piercing of 6.35 mm (±0.05 mm). This particular dimension corresponds to a 1/4 36 UNS 2B thread.

Materials and Platings

The components of the receptacle are made from a range of materials designed for durability and reliable electrical performance. The main body is constructed from stainless steel, ensuring a robust framework. For the center and outer contacts, beryllium copper is used, a material known for its excellent electrical conductivity and resilience. The insulator is made out of PTFE (commonly known by the brand name Teflon), which provides excellent resistance to high temperatures and chemical reactions. An aluminum alloy is used for the gasket component, while other parts remain in stainless steel to maintain the hermetic seal and mechanical strength.

Plating Specifications

In terms of platings, this datasheet details that the following components are coated for enhanced performance:

The body has a gold plating of 0.5 micrometers over a nickel base of 2 micrometers.
Both the center and outer contacts have a thicker gold plating of 1.3 micrometers, also over a nickel base of 2 micrometers.

Design Flexibility and Right to Update

It is important to note from the datasheet’s issuance details (with issue number 0449 F), that RADIALL, the manufacturer, reserves the right to make changes to the product in an ongoing effort to improve it. This indicates the potential for future modifications and enhancements to the receptacle’s design and specifications.

Engineering Drawings and Measurements

Accompanying the textual information, the first two pages of the datasheet are likely to include detailed engineering drawings. These provide a visual reference for the measurements of the component. All dimensions are represented in millimeters and the scale of the drawings is 1:1, allowing for accurate assessments when integrating the receptacle into a design or system.
