ANSI SCTE 200-2016 pdf free download – Specification for a 75 ohm ‘MMCX’ Connector (MMCX-75), Male & Female Interface
The purpose of this document is to specify requirements for the male/female interface of a 75 ohm, 3 GHz rated connector series generically known as MMCX-75. This is an indoor connector with applications in controlled environments such as headends and hubsites where high density platform chassis are used. MMCX-75 connectors are not intended to be mated with 50 ohm MMCX design counterparts.
All requirements of this document are measured after installation per manufacturer’s instructions of the cable into the connector. This document will address only the interface, not the connector body, the cable requirements, and the connector attachment to the cable or PC board. Mechanical, electrical and environmental performance is defined to ensure a reliable connection for permanent installations, as well as temporary adapters and calibration standards.

7.3.1. Insertion and Retention Force
Depending on whether the MMCX-75 interface connections are to be used individually or in conjunction with a multi-connector header, the required interface insertion and retention forces can vary. The data in this specification is for individual connector mating forces. Manufacturer specifications for the female socket insertion and retention forces should meet equipment requirements when tested as follows
7.3.1.1. Gauge A
Gauge A is to be inserted and removed from the female connector socket 5 times. Both insertion force and retention force are to be measured during the fifth insertion and removal.
7.3.1.2. After testing After testing is complete using Gauge A, then Gauge B is to be inserted and removed from the female connector socket while measuring insertion and retention force. For an individual MMCX-75 Female socket the maximum insertion force should not exceed 10 N and the retention force should not exceed 10 N using Gauge A. The minimum insertion force should not be less than .25N and the retention force should not be less than .25N using Gauge B.
7.4.1. Insertion and Retention Force Depending on whether the MMCX-75 interface connections are to be used individually or in conjunction with a multi-connector header, the required interface insertion and retention forces can vary. The data in this specification is for individual connector mating forces. Manufacturer specifications for the male plug insertion and retention forces should meet equipment requirements when tested as follows.ANSI SCTE 200 pdf download.
