KA Series 2 & 3 Row MIL-DTL-55302 QPL’D PCB Connectors

Category: Connectors, Electronics, Smiths Connectors

The datasheet features the HYPER HYPERTACCS KA Series 2 & 3 Row MIL-DTL-55302 QPL’D printed circuit board (PCB) connectors, which are designed to provide flexibility for applications that other connectors in this category may not offer. With over 2,500 possible model configurations, these connectors can accommodate a range of contact numbers, specifically 17, 29, 33, 41, 53, 62, 65, 72, 80.1, 84, 96, 98, 120, 126, 160, and 160.4 contacts.

Product Features

The connectors are designed with a 0.100 [2.54 mm] center grid, offset by 0.050 [1.27 mm] between adjacent rows to allow for straight PCB traces. Various terminations are supported, including straight dip, right angle solder, crimp, solder cup, and Wire Wrape. The male or female contacts boast a 0.024 [0.60 mm] diameter and have an average rating of 5 Amps current at a temperature rise of 30°C. Contacts have an average insertion and extraction force ranging from 0.3 to 2.0 ounces and are designed to be removable from the wiring side. Optional front release, front removable feature is available for receptacles with 160 contacts.

Performance Specifications

Contact resistance is maintained at milliohms, and the connectors are built for up to 100,000 life cycles. With a breakdown voltage of 1600V RMS between contacts and a dielectric withstanding voltage of 1200V RMS, they are robust for industrial applications. Insulation resistance stands at 10* Megohms at 500 VDC, and the connectors operate within a temperature range of -55°C to 125°C.

Materials and Construction

The insulator is made from diallyl-phthalate, while the contacts are constructed from beryllium copper with gold over nickel plating. Guide hardware is produced from brass or nickel passivated stainless steel. Different configurations offer 10uin and 50uin minimum gold over nickel plating on the maling surface and spin gold over nickel on the termination. Detailed dimensions for connectors with 17 to 65 contacts are provided, covering plug and receptacle variants.

Design and Mechanical Specifications

Connector dimensions are tailored according to the number of contacts, ranging from a plug dimension of 1.508 [38.30 mm] for 53 contacts to 3.909 [99.30 mm] for 65 contacts. The receptacle dimensions also vary accordingly. Key alignment and keying features are ensured by the end guides, and the datasheet provides 36 combinations that users can change.

Additional Information

A note indicates that the mated length of the connectors is typically 0.622 [15.80 mm], with a tolerance of 0.02 [0.50 mm]. The Wire Wrape trademark belongs to Gardner Denver, and all dimensions are provided in both inches and millimeters.
