Edge type connectors, like the DF17(4.0)-40DS-0.5V (57) are used to link two components together. These connectors are rectangular in shape and come in either a single row or double row arrangement. The type DF17 is a multi-pin connector for board-to-board applications, typically found on PC motherboards. It features a lockable design, which ensures reliable connections.

The DF17(4.0)-40DS-0.5V (57) rectangular connector is composed of a molded plastic body with various metal electrical contacts. The connector consists of a bottom side finger latch, signal contacts, a stainless steel shield shell, insulation, and top side finger latch. It contains 40 signal contacts, and supports a row to row spacing of 0.5mm. Its insulation voltage is 300 Volts. With an endurance of 500 cycles and a dielectric strength of 1500V AC ten minutes, this connector allows both horizontal and vertical connections.

This connector is typically used for the interconnection of PCBs in digital applications, including handheld scanners, resistive touch modules, Bluetooth modules, and small I/O devices. Its size and simple nature make it ideal for tight spaces and areas where a large number of contacts must be connected. It is especially useful for medical, networking, telecommunications, and industrial applications.

The working of the connector is quite simple. They connect two signals by creating an electrical contact when the latch slides inside the connector body. This electrical connection is then secured by locking the latch into the connector body. The connector is designed for one-sided assembly and the latch also enables easy mating and un-mating. Its compact design minimizes the risk of misconnection of the two components due to the finger latch molded into the front and rear sides.

The DF17(4.0)-40DS-0.5V (57) connectors are highly reliable and cost effective solutions for times where a low profile interface is needed with a small number of contacts. They help in downsizing of the entire system and their blind mating feature allow for easy installation. They are well suited for applications where low-profiles and physical security are needed.
