MM & MB series

MM & MB series

INTRODUCTION

The Radiall miniature and submaniature rectangular multicontact connectors meet the requirements of the standard mIL-C-28748

performance requirements.

They are rugged connectors and offer high performance for high contact density.

The connectors in each series consist of an insulator with male and female contacts which include several pin sizes.

FEATURES

Each connector features a male guide at one end and a female guide at the other. This arrangement ensures polarization of the

connector when coupled. These guides can be smooth (rack guides) or screw closing (fixed or rotating jackscrews).

The

contacts male or female

are made of copper base alloy plated gold over nickel. The female contacts have 4 slots which

ensures perfect mating, constant contact pressure and excellent mechanical and electrical performance. The contacts have a

slight amount of float in order to allow self alignment during mating.

Each series includes a different termination type; solder pot, straight or right angle solder pin for PCb, and wrapping.

The MM series

This series consists of six sizes of connector with contact arrangements for 7, 14, 20, 26, 34 and 50 size 22 contacts

Ø 0.76mm / 0.030inch.

The series offers four types of terminations:

• Solder pot for wire (AWG22 max)

• Straight solder pin for PBC

• Right angle solder pin for PBC

• Wire wrap

These connectors are fitted with rack guides or fixed or rotating jackscrews at each end. A protective covering for wire

terminations can be installed on the connector.

The MB series

This series consists of twelve sizes of connectors with contact arrangements for 2, 3, 5, 11, 14, 20, 25, 34, 42, 50 and 75 size 20

contacts Ø 1mm / 0.039inch.

The series offers three types of terminations:

• Solder pot for wire (AWG20 max)

• Straight solder pin for PBC

• Right angle solder pin for PBC

These connectors are fitted with rack guides or fixed or rotating jackscrews at each end.

Wires and soldered terminations for wire can be protected by either top or side entry backshells or by potting covers for 2 to

14 contacts connectors.

A range of

top and side entry backshells

with cable clamps in yellow anodized aluminium alloy are available. They are designed

to protect the soldered wire connections, provide strain relief to the cable and facilitate the disengagement of the mated

connectors.

Fitted with threaded posts they are suitable for connectors fitted with rack guides or fixed jackscrews. When fitted with

rotating jackscrew guides they are fixed to the connectors without guides and jackscrews.

For the mb series there are also thermoplastic covers for “potting” ensuring that the terminated wires at the

back of the insulator are protected.
