Samtec TLW Series Straight Through Hole Pin Header, 40 Contact, 2.54 mm Pitch, 2 Row, Unshrouded TLW-120-05-G-D

Samtec TLW-120-05-G-D is a precision-engineered straight through hole pin header featuring 40 male contacts arranged in 2 rows with a 2.54 mm pitch. This unshrouded header uses a liquid crystal polymer housing that offers excellent mechanical strength and resistance to heat, making it suitable for demanding electronic component applications.

Contacts are fabricated from phosphor bronze and plated with 0.25 μm gold to ensure low contact resistance and durability in high-reliability environments. The contact tail pin length of 4.32 mm and mating pin length of 2.67 mm facilitate robust solder joints and secure mechanical engagement with mating connectors.

This board-to-board and wire-to-board connector system supports up to 3 A current per contact and is rated for operation in a temperature range of -55°C to 125°C, ideal for industrial, laboratory, manufacturing, and electronic device assembly contexts.

The low profile and unshrouded design optimize PCB space usage, while the through-hole mount type provides secure mechanical strength against vibration and mechanical stress in production environments.
