QSE-040-01-L-D-A-K-TR Connectors, Interconnects

QSE-040-01-L-D-A-K-TR is an edge connector array designed to mate between printed circuit boards (PCB) to form electrical connections. It is one of a range of products in the rectangular connectors - arrays, edge type, mezzanine (board to board) family, which are designed to provide accurate connections in application areas such as computer, telecom, industrial and medical equipment.

The connector consists of an array of 40 contacts, each being in a lead-in diameter of 1.27 mm and a spacing 0.15mm, which allows for a range of electrical connections. It has two rows of staggered pins that connect the top and bottom boards with each other. The pins must be precisely aligned for a reliable connection. It is therefore important to note that this connector is designed for double-sided mounting.

The lead-free RoHS compliant connector is designed in accordance with the IEC 61076-2-101 “Rectangular connectors – Part 2-101: Detail specification for mezzanine connectors with soldered contacts for board-to-board and cable-to-board applications”. It features a low profile of just 10 mm above the circuit board, providing maximum space savings. It is also well suited for areas where vibration and EMI susceptibility are major concerns.

Its design features a metal shell, consisting of a base body and top housing. The contacts are made of stamped and formed baffled contacts with metal materials and are designed for wave soldering. This connector is also compatible with many mating connectors such as 2x4, 2x8, 2x10, 2x14, 2x20, and 2x40, supporting various signal configurations and allows for maximum performance in different applications.

The connector is widely used in applications requiring high reliability and durability, such as consumer electronics, industrial automation, data acquisition, medical and security systems. It can be used to connect different types of PCBs, including boards of different sizes, and can be configured for various pin formations by adding or removing contacts form the array. It is also used in communication systems, industrial automation systems, and embedded systems.

The working principle of this connector is simple. It connects two printed circuit boards (PCB) formed of a pair of mating connectors. Since the pins are precisely aligned, the connection formed between the two boards ensures a reliable transmission of energy and data signals. The pins inside the connector are also supported with connectors, allowing them to be securely locked when they are engaged. Furthermore, the contact forces provided by the connectors are strong enough to ensure the best possible performance over long periods of time.

In conclusion, the QSE-040-01-L-D-A-K-TR edge connector array is specifically designed to provide reliable, accurate connections between two printed circuit boards. It is available in several different pin configurations and is suitable for a wide range of applications. It features a metal shell which provides excellent stability and secure connection. It also features stamped and formed baffled contacts which allow for wave soldering.
