RSM-140-02-S-D-P Application Field and Working Principle

Rectangular connectors, including headers, receptacles, and female sockets, are usually used to carry signals and power between two electronic circuit boards. They come in a wide variety of configurations, with various sizes, contact arrangements, shapes, and designs. One such example is the RSM-140-02-S-D-P, which is a highly reliable and versatile rectangular connector.This rectangular connector is shaped like a square with two rows of four contacts each. It is commonly used for power and signal connections in a variety of applications, such as in industrial, automotive, audio/video, and medical equipment. Its small and compact size makes it ideal for applications where space is limited. The contacts and housing of the connector are made of high-quality and durable materials, making them resistant to oxidation as well as temperature and vibration extremes.The RSM-140-02-S-D-P comes with two types of pins, the Type S and Type D. The Type S pins are used as power pins and provide a male-female connection. The Type D pins provide a male-male connection and are typically used as signal pins. The pins are mounted in two rows of two separate sockets which are keyed to provide stability in the connection. The pins are housed in a zinc alloy housing and sealed with an epoxy resin for protection against vibration and debris.The working principle of this rectangular connector is quite simple. It has two main components, the contact and the housing. When a compatible mating part is inserted in the housing, the contacts inside the socket engage and establish a connection. The contact is made of a metal such as copper, brass, or steel and is secured firmly in the housing. The contact ensures a solid and reliable electrical connection between the two boards.The RSM-140-02-S-D-P has a number of advantages over other types of electrical connectors. Firstly, the contacts are stationary and therefore provide a more consistent connection. This consistency is beneficial in applications where the connection is subject to frequent movement or vibration. Secondly, the housing is made of a zinc alloy which increases its strength and durability. Finally, the pins and housing are sealed to keep out dust and debris, making it perfect for use in harsh environments.In conclusion, the RSM-140-02-S-D-P is a highly reliable and versatile rectangular connector. It is used in a wide range of applications and its small size and durable construction make it a great choice for space-limited and challenging environments. The contacts and housing provide a reliable connection, and the pin seals ensure that the connection is protected from dust and debris.
