Product catalog summary

Technical Characteristics

Materials and Finishes: The insulator is made of glass-filled polyester, UL 94V-0, in blue color. Contacts are precision-machined copper alloy with gold flash over nickel plate, with other finishes available upon request.
Electrical Characteristics: Contact current ratings are detailed per UL 1977. Size 20 power contacts support 24 amperes continuously with all contacts under load. Initial contact resistance is 0.001 ohms maximum per IEC 512-2, Test 2b. Insulator resistance is 5 G ohms per IEC 512-2, Test 3a. The working voltage is 200 V r.m.s, with a minimum creepage and clearance distance of 2.0 mm [0.079 inch].
Mechanical Characteristics: Features a blind mating system with a 1.0 mm [0.039 inch] diametral misalignment allowance. Polarization is provided by contact arrangement. Fixed contacts are for printed board terminations, with female contacts featuring a 'Closed Entry' design. Fixed contact retention in the connector body is 40 N [9 lbs.]. Sequential contact mating system is available, with power enabled through a last mate contact within the VPX Series or another connector. Mechanical operations are rated for a minimum of 250 couplings.
Climatic Characteristics: The working temperature range is -55˚C to +125˚C.

Application Features

The VPX series supports VITA 41 VXS (VME Switched Serial) for high bandwidth transfer between VMEbus cards, providing a dedicated power interface between boards and backplanes.
The series is compatible with conduction cooled boards per IEEE 1101.2, featuring multiple power contacts, three levels of sequential mating, and high reliability.

Ordering Information

Connectors are specified using a code numbering system, with options for environmental compliance, connector variants, gender, type of contact, and contact plating.
RoHS compliance options are available, and specific mounting screws are recommended for PCB attachment.

Dimensions and Tolerances

All dimensions are in millimeters [inches] and are subject to change. Tolerances are specified for various dimensions, including contact mating and termination diameters.
