Rectangular Connectors - Headers, Receptacles, Female Sockets

ESQ-111-69-S-T-LL is a type of Rectangular Connectors suitable for header and connector applications. It is widely used for on-board electrical connection for a variety of equipment and systems. It consists of a pair of male (or header) and female (or receptacle) components that are mated together. It meets IEC/EN 61984-2 standards for voltage and current. It is high pin count, reliable and cost-effective, making it an ideal choice for a variety of applications.

Application Field

ESQ-111-69-S-T-LL is an ideal choice for a variety of applications, such as personal computer systems, industrial automation, domestic and commercial electronics, automotive applications, telecommunications, high end consumer electronics, as well as digital and portable devices. Its robust design and ability to support a large number of pins makes it ideal for a variety of applications. It is suited for applications where high reliability and performance is required, such as digital, analog and power applications.

Working Principle

ESQ-111-69-S-T-LL utilizes a two-way in-line contact system for connecting pins or conductors. It has a central cavity for the male pin which is then inserted into the female receptacle segment. When mated together they form a secure connection by compressing the contact against the pin\'s metal surface. The more the contact is compressed the higher the electrical and mechanical performance. The connector is easy to assemble and disassemble, making it suitable for dynamic applications.

ESQ-111-69-S-T-LL also offers robustness, reliability and good contact repeatability. The connector has an integral polarizing key (or guide) which enables mating of header and receptacle in only one direction. It is also designed to reduce electromagnetic interference. When the connector is in use, the \'straight\' path for the electrical current helps maintain low impedance, allowing the connector to pass necessary signals with high fidelity.
