Circular Connectors are a type of electrical connectors, which is used for attaching the wiring of electronic applications. It is composed of two or more components, which can be easily assembled and disassembled. The design of the circular connectors varies from simple one-piece male and female receptacle/plug to complex multi-port connectors with threaded coupling.

SD-70 is widely used in a variety of electrical applications, as they offer reliable electrical connection without the interference of moisture or airborne contaminants. It is a circular connector designed for cross-sectional wire contacts with an operating voltage rating of 1000 volts. The contact type of SD-70 includes combination hermaphrodite, female/male, male/male, and male/female contacts. It is an ideal choice for signal and power applications, as the contacts latch into each other for secure and positive locking.

The SD-70 connector consists of four primary components, including a shielding shell, main body, indexing bar, and contacts. The shielding shell is made of a die-cast alloy or zinc alloy. It is designed to protect circuitry from harmful external influences, including electromagnetic interference and thermal shorts due to contact fluctuations. The main body is composed of machined aluminum, and it acts as a housing for the contacts. The indexing bar is used to fixate the contacts and ensure that they remain in the correct position when in use. The contacts come in two categories – male and female – and are usually stainless steel or a similar material.

The working principle of the SD-70 connector is relatively straightforward. The contacts are first inserted into the main body of the connector, and then the shielding shell is placed over the contacts. The shield provides Conductive Pathway (CPA) for signal and unintentional ground-level emissions. Once the contacts have been affixed in the slots, the indexing bar is attached to keep the contacts in place. When the male and female halves of the connector are mated, the contacts are connected, thus forming a reliable electrical connection with minimal interference and signal loss.

The SD-70 circular connector is an ideal choice for a variety of applications, due to its reliable electrical connections, resistance to environmental factors, low contact resistance, and EMF protection. It is commonly used in instrumentation, industrial, medical, and communications equipment, and is also well-suited for low-voltage power distribution.
