Rectangular connectors, including headers, receptacles, and female sockets, are among the most popular electrical connectors. 533514-6 connectors are especially suited for high-density applications. While 533514-6 connectors look nearly identical to their counterparts, they are in fact specialized in several ways.

Overview

533514-6 connectors are designed and machined according to the MIL-DTL-55302 Specifications. This style of connector is designed for environments where there is a high vibration or shock motion, with a backing shell to protect the contained components. The 533514-6 electric connector has an insertion force of 0.15N, a working voltage of 400V, and an operating temperature of -55°C to +125°C. It has an insulation resistance over 1GΩ, an insertion and extraction life of 500 cycles of the MIL-DTL-55302, and is available in a variety of sizes. It is designed for application with 10, 16, and 20 pin headers and a variety of female sockets arranged in two-piece shells.

Pins and Cavities

533514-6 connectors typically feature a 1.8 mm x 1.4mm foot print on a header with 24 cavities in a single block. Each of the cavities supports 1 pin which typically uses the back cover as a shield to maintain a volume of 0.161 cubic inch. It also features two detent options, three plating options, two shell mounting styles, and two pin material options. The pins and contacts within the 533514-6 connector are typically made from either copper alloy or beryllium copper and come in a variety of plating options, including copper, gold, and tin.

Benefits

Due to the high-density nature of the 533514-6 connectors, they are ideal for applications where space, weight, and power consumption are at a premium. The one-piece design eliminates the need for bulky brackets and clips and its low insertion force makes it easy to use. 533514-6 connectors are also highly resistant to accidental shorts, providing a high degree of safety and reliability. Additionally, the connectors are RoHS and REACH compliant, making them suitable for mass production and applications.

Applications

533514-6 connectors are used in a variety of applications, including in consumer electronic products, automotive systems, medical equipment, telecommunications, power supplies, and test and measurement equipment. Its compact size makes it suitable for portable or embedded appliances and equipment, while its strong build quality makes it suitable for industrial applications. 533514-6 connectors are also often used in high vibration or motion environments, such as military systems, aerospace systems, and robotics.

Working Principle

The basic functioning of the 533514-6 connector relies on its ability to provide a secure electrical connection without disruption. This is achieved by the combination of the connector’s internal components. The contact spring is typically utilized to provide electrical continuity between the PC board and the enclosure. The contact spring is attached to the socket assembly and the pin contacts in the 533514-6 connector are inserted into corresponding blade slots in the enclosure wall. The contact springs are tensioned so that the pins are firmly secured in place when inserted.

To ensure a reliable electrical connection, a removable foam plunger ensures proper contact between the blade and the contact spring. This maintains electrical continuity even in vibrations or motion. Lastly, the connector’s casing is designed to be both shock and moisture resistant, making it suitable for use in harsh environments.

Conclusion

533514-6 connectors are designed as high-density electric connectors used in extreme environmental conditions. This type of connector offers design flexibility, resistance to accidental shorts, an easy insertion and extraction process, and RoHS and REACH compliance. Additionally, its one-piece design eliminates the need for cumbersome brackets and clips. 533514-6 connectors are an ideal choice for a variety of applications ranging from consumer electronic products to military systems.
