0.050" Pitch Miniature Spring-Loaded Contacts

Mill-Max 0.050" Pitch, Miniature Spring-Loaded Contacts include compact pins and connectors designed for 0.050" pitch applications. The pins: the SMT and through-hole versions each feature an above-board height of just 0.166 inches and a full-stroke capability of 0.040 inches. These spring-loaded pins are crafted with precision-machined components and stainless-steel springs, all meticulously gold-plated to guarantee optimal conductivity, corrosion resistance, and long-term endurance. The pins boast a minimum durability of 100,000 cycles at half-stroke, consistently meeting electrical and mechanical specifications. Electrically, these pins are characterized by a contact resistance of under 20mΩ and a maximum current rating of 7A at a 30°C temperature rise. The pins also fulfill the shock and vibration requirements of IEC standards 60512-6-3 and 60512-6-4.
