Horizontal Surface Mount (HSMT) Spring-Loaded Pins

Mill-Max Horizontal Surface Mount (HSMT) Spring-Loaded Pins are designed for making low-profile connections parallel to the board surface. These spring-loaded pins have plunger travel in-line with the board surface, making them ideal for end-to-end board connections in assemblies with restrictive height requirements. The rated travel ranges from .0195" to .059" (0.5mm to 1.5mm) with associated maximum travel options of .039" to .118" (1mm to 3mm). Each HSMT spring-loaded pin has ample surface area for SMT soldering, ensuring secure attachment to the board to stand up to rough handling, particularly in blind mating and quick-connect applications. They are typically mounted near the edge of the board with the plunger extending beyond the board edge to make contact with a target on a mating board or device. Each component, including the spring, is made of high-quality materials and gold plated to ensure high reliability, corrosion and wear resistance, resulting in a durability rating of up to 1,000,000 cycles.
