Avionics, Electronics & Interconnect
Rectangular & Modular Connectors
Rectangular and modular connectors carry signal, data and power across avionics, electronics and interconnect assemblies where space, position count and termination method must be controlled precisely. The family spans Micro-D and D-subminiature connectors, modular wire-to-board and wire-to-wire housings, and multi-position rectangular inserts used throughout defence, aerospace and industrial electronic builds.
Product-type coverage
- Micro-D connectors (micro-miniature rectangular, high-density signal)
- D-subminiature (D-sub) connectors — plug and receptacle
- Modular wire-to-board connector housings
- Modular wire-to-wire connector housings
- Multi-position rectangular connector inserts and shells
- Associated contacts, backshells and accessories (quoted to specification)

Typical selection attributes
This page is the product family. The filters — type (Micro-D / D-sub / modular), position count, termination and gender — narrow within the family; they do not create separate categories. Use the family page to browse the full range, then apply filters to isolate a specific configuration once the filterable product table is populated.

Frequently asked questions
What is the difference between rectangular and modular connectors?
Rectangular connectors use a rectangular shell or insert and include types such as Micro-D and D-subminiature. Modular connectors use housings populated with discrete contacts, typically in wire-to-board or wire-to-wire configurations. Both are selected by type, position count, termination method and gender.
Which connector types does this family cover?
It covers Micro-D and D-subminiature (D-sub) connectors, plus modular wire-to-board and wire-to-wire housings and multi-position rectangular inserts. Use the type, position, termination and gender filters to narrow to a specific configuration.
Can I request a connector by its military part number?
Yes. You can submit a part number from a recognised series such as M83513 (Micro-D) or M24308 (D-sub) for identification. These references are used to match your requirement for RFQ; they are not a statement of certification or compliance held by BOLTON.
How do I select the right connector?
Confirm the connector type, position (contact) count, termination method and gender, then any mounting, keying or locking requirement. Provide these on your RFQ — with a manufacturer series, part number or drawing if available — and we will quote against the specification.
Do you supply mating contacts and accessories?
Mating contacts, backshells and related accessories can be quoted to your specification. List what you need on the RFQ so the requirement can be matched and quoted together.
