Terminal Blocks - Headers, Plugs and Sockets are used to physically interconnect electronic equipment. The OSTTS22115D is a terminal block/socket specifically designed for a wide and versatile range of applications. The variety of applications of the OSTTS22115D terminal block/socket includes industrial control applications, assemblies and wire harnessing secure the connection of two or more cables, electrical switches, circuit breakers, surge protectors, wall plugs, fuses, circuit boards and LEDs. It is designed to securely connect and power electrical components, ensure the highest quality connection and reliability.The OSTTS22115D is constructed of a low- Profile housing that accommodates and provides a secure fit for the header pins. This ensures a firm and consistent clamping force when cable is inserted into the header, which makes it ideal for applications in tight spaces and modularized solutions. The width of the OSTTS22115D is only 8mm, allowing it to be configured to fit various shapes and sizes. The 26 AWG rated UL 94V-0 flame-retardant natural polyethylene insulation incorporated into the housing components add protection to the internal components as well as prevent electrical shorts.The OSTTS22115D has a two-part design, which consists of a header and a socket. The header is a cylindrical housing with multiple slots for wires and two pins to connect the header to the socket. The socket is a circular housing with a recessed area to allow the header pins to fit snugly. The connection between the header and the socket is secured by a latch mechanism that prevents the header from sliding out of the socket when the connection is made. The OSTTS22115D also features a sealable pre-wired connector which securely locks in the connection and can be sealed, protecting it from vibration, moisture, dust and other external elements. This feature makes it very suitable for outdoors applications and in harsh environments. The OSTTS22115D also consists of a robust male/female coupling system providing a secure connection that will not become loose over time or with vibrations. This makes it highly reliable and suitable for applications dealing with heavy-duty power connections. The working principle of the OSTTS22115D is quite straightforward. The header and socket are inserted into each other and the two pins on the header are pushed into the recessed area of the socket. When this is done, the latch mechanism engages and the connection is secured. The pre-wired connector then locks the connection in place and can be sealed to provide additional protection. In summary, the OSTTS22115D terminal block/socket provides a reliable connection for applications in various industries, while incorporating features that ensure the highest quality connections and protection against harsh conditions. The two-part design of the OSTTS22115D is easily configured and offers a secure and reliable connection with a pre-wired connector that ensures a reliable power connection that will not become loose over time.
