Rectangular Connectors - Headers, Receptacles, Female Sockets

ESW-104-34-S-D-LL Application Field and Working Principle

Rectangular connectors are the most common type of connectors used in electronics. They have been used for many years in a variety of applications from automotive, aviation, lighting, medical, military and commercial communication. ESW-104-34-S-D-LL is a special type of rectangular connector, which often has different contact arrangements, polarizations, mechanical orientations and keying systems. It plays an essential role in connecting and providing power signals for the circuit board.

Application Field

ESW-104-34-S-D-LL connectors are widely used in various industrial fields. Common application fields are as follows:

• Automotive & Aviation Electronics: Airbag systems, power and navigation systems, sensors, displays, etc.
• Industrial Power & Electronics: Industrial control, servo control, PLC, HVAC, water treatment system, stage lights, etc.
• Medical Equipment: Imaging and diagnostic systems, patient monitors, imaging devices, etc.
• Automation and Robotics: Automotive production, industrial robots, Laser processing systems, etc.
• Military Network and Telecom: Radar, fire control systems, connectivity systems, communication systems, etc.

Working Principle

ESW-104-34-S-D-LL connectors are usually used in two types of connection, cable-to-board and board-to-board. The primary function of the connector is to electrically interconnect two or more components. It can also be used to provide mechanical support or physical strength to ensure reliable overall performance.

In cable-to-board connection, the female header of the connector is mounted on the PCB while the male header is soldered to the cable. In board-to-board connection, a male header is mounted to one board while the female header is then inserted into the receptacle on the other board to make a connection. The contacts of the connector mechanically and electrically engage with the mating contacts and then secure the connection using a latch. This ensures a good electrical connection between the two components.

The connector is typically made of high-performance insulating polyimide and its contacts are made of phosphor bronze, which has good electrical and thermal conductivity. The connector is designed to provide dependable and reliable connections while withstanding the high mechanical and electrical stresses. It is also waterproof and meets the UL, VDE, and CSA standards.
