TECHNICAL CHARACTERISTICS

Positronic’s Combo-D connectors are a popular choice for a

wide variety of applications. Many options make the Combo-D a

versatile connector choice.

CBDD high density series connectors are quality connectors

recommended for use in sheltered, non-corrosive indoor and

outdoor environments having normal ventilation, but without

temperature or humidity controls.

CBDD series connectors offer mixed contact combinations

of power, signal, and thermocouple contacts within the same

connector body.

CBDD series connectors utilize precision machined contacts

offering high reliability. Connector variants are available with

straight and right angle (90°) printed board mount terminations,

including compliant press-fit. For cable connectors see CBCD

section, page 39.

Female power contacts feature the Large Surface Area (L.S.A.)

closed entry contact design, which provides maximum mating

surfaces between male and female contacts and reduced contact

resistance during operation.

Fixed signal contacts are available with open entry female

contacts, professional level or PosiBand closed entry female

contacts, industrial level. Military contact plating is optional.

A wide assortment of printed board mounting hardware, cable

support hoods, and locking systems is available from stock.

A blind mating system is available for applications requiring

connector coupling in recessed areas or mobile power coupling

systems.

Straight and right angle PCB mount thermocouple contacts

are available, please contact Technical Sales for details.

CBDD series connectors utilize precision machined contacts

and meet applicable performance and dimensional requirements of

IEC 60807-7, MIL-DTL-24308 and AS39029.
