MS25043-32D Connectors, Interconnects

Circular Connectors - Accessories

MS25043-32D is a circular accessory of the MS25043 series connectors, produced by Marysville Corporation. The MS25043 series is used for motorized vehicles, general aviation, and commercial aviation applications. The series also features a variety of Circuits, Contacts, and Insert Arrangement.

The MS25043-32D consists of a four-piece connecting device, comprising of two mechanical contacts, two full shells (upper and lower), and a flexible seal. The mechanical contact is composed of a formed leaf spring that provides the locking feature and a contact arm incorporating one internal and one external contact. The full shell includes a mounting flange, which is used to secure the connector to a bulkhead. It is designed to provide a 360-degree environmental seal for the contacts. The flexible seal is designed to provide a dust seal and additional environmental protection.

The MS25043-32D is designed for applications that require quick mating and unmating. The spring loaded form contact arms provide a positive retention force and audible click when the connector is properly mated. The upper and lower shells mate with each other and the flexible seal attached to the upper shell. The contact arms are usually soldered into the mating cable assembly.

The MS25043-32D can be used in many applications, including commercial aircraft, aerospace vehicles, military aircraft, commercial vehicles, marine applications, as well as other motorized vehicles. Its quick mateability and durability make it a suitable choice for many environments. It is designed to ensure proper connection and durable performance in adverse conditions such as temperature change, vibration, and high-speed operations.

The working principle of the MS25043-32D is quite simple. Once the connector is mated, the spring-loaded contact arms makes a positive retention force with audible click. This ensures that the electrical connection is secure. The upper and lower shells then fully seal the connection against dust and other environmental effects as well as offer EMI/RFI protection.

Overall, the MS25043-32D is an ideal choice for automotive, aviation, military, and other applications where durability and superior electrical performance are required. It is particularly suitable for applications where frequent mating and unmating is required, such as in motorized vehicles. The incorporation of a flexible seal also adds increased environmental protection, which makes it ideal for harsh or extreme environments.
