Samtec ESQ Series Vertical Through Hole PCB Socket, 20-Contact, 2 Row, 2.54 mm Pitch, 5.7A, Black Glass ESQ-110-33-T-D

Samtec ESQ-110-33-T-D is a high-quality ESQ series vertical through hole PCB socket featuring 20 contacts arranged in 2 rows. It is primarily designed for board-to-board connector systems, offering secure and reliable electrical connections in electronic assemblies.

The socket uses a durable black glass filled polyester housing engineered to withstand demanding operating conditions. Its contact elements are made of phosphor bronze with matt tin plating, providing excellent conductivity, corrosion resistance, and mechanical robustness.

This PCB socket supports a nominal current of 5.7 amperes per pin and operates safely within the temperature range of -55°C to 105°C, making it suitable for industrial, commercial, and laboratory electronics applications. The standard 2.54 mm pitch and solder termination type facilitate compatibility with PC/104 applications and ensure stable soldered joints.

The normal contact force for standard insertion is calibrated at 125 grams (4.4 Newtons), ensuring low insertion forces for ease of assembly, yet maintaining firm electrical contacts. The product is rated for up to 100 mating cycles with 10 microinch (0.25 micrometer) gold plating on contacts, assuring durability and repeated reliable connections over time.

Its vertical orientation and through hole mounting allow for strong mechanical fastening on printed circuit boards, enhancing product longevity and robustness in various electronic designs. The connector system classification as board-to-board enables modular and scalable electronic arrangements in industrial automation, instrumentation, communication devices, and other high-reliability electronics.

Rated current per contact is 5.7A ensuring high capacity for signal and power transmission. Standard pitch of 2.54 mm promotes wide compatibility with common PCB layouts. Durable black glass filled polyester housing resists heat and mechanical stress effectively.

Phosphor bronze with matt tin plating offers corrosion resistance and excellent electrical properties. Designed for vertical through hole mounting ensuring robust mechanical connection. Wide operating temperature range from -55°C to 105°C supports diverse application environments.

Supports at least 100 mating cycles due to gold plated contacts. Optimal insertion force at 125 grams balances ease of use and contact reliability.

This product is ideal for use in industrial, manufacturing, communications, and laboratory electronic equipment where dependable board-to-board connectivity is essential to performance and durability.
