HTST-110-04-G-D-RA

The Samtec HTST-110-04-G-D-RA is a 20-position, dual-row shrouded header designed for board-to-cable/wire applications. It features a 2.54mm pitch and row spacing, with a right-angle through-hole mounting style. The connector is fully shrouded with a 4-wall design, providing polarization and protection for the male pin contacts. Gold plating on the contacts ensures reliable signal integrity and corrosion resistance, with a contact finish thickness of 10.0µin (0.25µm). The insulator is molded from liquid crystal polymer (LCP) with a UL94 V-0 flammability rating, and the natural color aids in visual inspection.

This header is rated for 3.4A per contact and operates over a temperature range of -55°C to 125°C. The contact material is phosphor bronze, and the square pins have a length of 6.35mm. A keying slot feature prevents mis-mating, ensuring correct orientation during assembly. The connector is packaged in tubes with a standard quantity of 17 parts per package.

Ideal for applications requiring high-temperature tolerance and reliable interconnections, the HTST series is commonly used in data communications, industrial controls, and test equipment. The right-angle orientation allows for low-profile connections parallel to the board, saving space in dense layouts. The push-pull fastening type provides secure but easily disconnectable mating.
