The HM-H125B1-5CS1-TG30 is a hard metric connector often used in commercial backplane applications. This connector type is based on the standard two-row design, but has been upgraded with an innovative design that improves electrical performance and high-speed transmission. It fits into a 5 mm pitch and provides a secure connection between boards that enable multiple layers.The HM-H125B1-5CS1-TG30 has an impressive connection density, with a design that offers up to 50 lines per cm, making it ideal for high-density applications. With an industry leading insertion force of 50N, it is also suitable for extremely dense 100-layer boards. The fine pitch means every row has five solder tails, providing a high connection density and a robust connection between the two boards.The HM-H125B1-5CS1-TG30 is a flexible connector, designed to fit a wide range of applications, from standard backplanes to high-data-rate applications. The design features a high number of poles and an optimal design ratio between small-sized contact height and high-speed performance. This design enables a reliable and fast connection as the contact points have a high-speed transmission rate with low crosstalk. The connector also features four plated areas to reduce the risk of damage due to high temperature and enhances connection reliability even under high temperature conditions.The HM-H125B1-5CS1-TG30 has a reliable and favourable working principle. It has an inverted four-row design providing superior signal transmission to give a better transfer rate. The male and female contact points are designed with spring-like spiral arms, allowing for a secure and reliable connection. The contact points have two contact fingers on each pole, creating a firm, stable connection, providing good electrical performance.The connector also has a tight fit structure meaning it won’t move or turn when it’s screwed together. The anti-rotation device prevents the connector from turning when it is connected to the board, and the locking levers ensure a solid connection with a locking force that has been optimised for demanding applications such as high-speed, high-power connections.The HM-H125B1-5CS1-TG30 is an exceptionally reliable backplane connector, designed to improve efficiency and reduce connection time, suitable for applications that require excellent electrical performance with high-speed signals, such as computer networks, telecommunications, automotive, optical networks and data centres. This connector type is especially popular in military applications as it has a high resistance to shock, vibration and harsh environment requirements.
