MMS-125-02-F-DH Application Field and Working Principle

Rectangular connectors are connectors with dimensions that vary from round connectors. They are used in a variety of applications and are available in several different configurations. Further, they are available in a variety of shapes, sizes, and contacts.

The MMS-125-02-F-DH is a rectangular connector family that is commonly used in the field of electrical connection. It is a multi-dwelling plug and is designed for use in panel mount or in-line mount applications. The particular configuration chosen offers a high density of contacts in a small space.

Application Field

The MMS-125-02-F-DH is used in a range of applications such as industrial control systems, automotive control systems, and medical equipment. It is ideally suited to be used with thicker wires as it offers higher contact force in order to secure the cables firmly in place.

It is also used in data transport applications, in which it is necessary to use multiple layers, as it offers an integrated contact system and is able to reduce the number of contacts. The connector can also be used in distributed design systems, as it is manufactured with RoHS compliant materials.

Working Principle

The MMS-125-02-F-DH plug is a 2-pole, 2 row, 3mm pitch, push-pin type plug. It consists of two rows of gold plated contacts that are spring loaded and have a built-in locking mechanism. It is designed to ensure a positive lock between mating connectors using a spring-loaded plunger latch located at the back of the plug.

The contacts are arranged in two rows and are angled, which allows them to be used in applications where there is a tight bend radius, such as in panel mount applications. The contacts are preloaded, meaning that they are spring loaded and maintain pressure against the mating contacts. This ensures a reliable and secure mating even when subjected to vibration.

The contacts are designed to offer secure connections for 500 mating cycles and offer a current rating of 2 A per contact. The plug contact materials are lead-free and comply with all applicable RoHS standards. The plug is designed with two keyed versions — straight and offset.
