M39012/31-0004 KA-71-02 Bulkhead Receptacle TNC Datasheet

Category: Connectors, Electronics, Winchester Electronics Corporation

Overview

The datasheet provides detailed information about the KA-71-02 SCNu 41, a bulkhead receptacle TNC connector with the part number M39012/31-0004. This connector is designed for use in applications requiring a controlled impedance of 50 ohms and can operate within a frequency range of DC to 11 GHz.

Physical Characteristics

The external hardware includes a 7/16-28 UNEF-2A threaded interface and a hexagonal body measuring 50 hex ref (reference dimension) in width. The receptacle allows a maximum panel thickness of .13 with a mounting hole size denoted as ‘VOVNNG HQLE’ – the exact measurement not clearly stated in the content provided. A lockwasher made of phosphor bronze is used for securing the receptacle, as noted in the document. The datasheet includes a stamped date code ‘91836’ for identification purposes.

Materials and Finishes

The materials used in the manufacturing of the connector include a TEFLON insulator complying with ASTM-D-4894 standards, while the center contact is made from beryllium copper as per ASTV-B-196 standards. The remaining metal parts are constructed from brass, adhering to ASIV-B16 specifications. The finishes involve a cold plate per MIL-G-45204 for the center contact, and all other metal parts are silver-plated in accordance with QQ-S-365.

Electrical Characteristics

Nominal impedance is maintained at 50 ohms, with the device able to handle a working voltage of 500 volts RMS. The frequency range compatibility extends from DC to 11 GHz, suitable for a broad array of RF applications.

Regulatory and Compliance

The datasheet specifies that the connector’s interface adheres to MIL-STD-348 standard figure ‘J1J-2’. However, due to the format of the provided content, full compliance information is not clearly stated.
