Rectangular Connectors – Spring LoadedRectangular connectors with spring loaded contacts are ideal for a variety of applications. The 821-S1-004-30-012191, commonly known as a `R-CNC or R-DIN`, is a connector with a single row of spring loaded contacts which spring actuate when engaged by a mating connector. This connector type offers faster installation and connection than traditional connector types due to the spring loading of the contacts. The 821-S1-004-30-012191 connector is an all-metal connector encased in a stainless steel housing for superior protection and durability. Its spring loaded contacts are designed for quick and reliable electrical connections, providing vibration resistance and preventing damage from impacts. The mechanical keying system ensures that the connector can only be mated with an appropriate mating half. The 821-S1-004-30-012191 connector is particularly suitable for use in computers, communications, medical or industrial automation applications. Its robust performance enables reliable, stable electrical connections even in challenging environments such as those found in transportation, heavy vehicles and off-road construction equipment.The 821-S1-004-30-012191 connector consists of a Housing/Cup receptacle with a positive latching, and a Plug insert containing spring loaded contacts. The Housing/Cup receptacle holds two sets of gold plated contacts; one set of contacts is formed on the receptacle, while the other set is held in a Plug insert. The Plug insert is made from an injection molded nylon material and it accepts the spring loaded contacts which protrude from the contact holes.The 821-S1-004-30-012191 connector\'s spring loaded contacts are designed to properly secure the connections and prevent the accidental disconnection of mating halves. When the connector is mated, the contacts provide a secure electrical connection. The contacts are constructed of a special alloy of tin-plated copper, enabling them to provide superior electrical performance in applications requiring high frequency and/or high voltage operation.The 821-S1-004-30-012191 connector also features an anti-shorting feature. This feature ensures that the contacts are properly mated and eliminates arcing between adjacent contacts. The mechanical keying system also prevents incorrect mating of the connector halves and prevents the connector from being mistakenly connected to a power source or other dangerous electrical circuit. The 821-S1-004-30-012191 connector can be installed in a variety of applications such as power distribution systems, computers, printers, testing instruments, communications systems, and data equipment. The connector is also commonly found in a variety of industrial automation and robotic applications. The rugged construction of the connector ensures reliable performance in arduous environments, while the spring loaded contacts provide high-speed connection and disconnection with superior vibration and shock resistance. In summary, the 821-S1-004-30-012191 connector is a reliable, safe and secure connector suitable for a vast array of applications. Its spring loaded contacts enable quick and reliable connections, while the mechanical keying system and anti-shorting feature ensure proper mating and prevent incorrect connections. The robust construction of the connector ensures long-term reliability and performance in the most demanding applications.
