Press Fit Header 55 Signal Contacts 2 Millimeter Type C Left Guidance 3M CP2 HC055 A1 KR Connector
Product Overview
The 3M CP2 Press-Fit Header, 2 mm Type C, features 55 signal contacts with left guidance. Designed for high signal density at a low cost, this header utilizes an "Eye of the Needle" compliant pin press-fit system to streamline manufacturing. It offers three contact mating levels for Early Mate Late Break or "Hot Swap" applications, reducing manufacturing time and cost. Feed-through termination is available for midplane applications, and additional grounding rows can be incorporated for enhanced ground bounce and EMI immunity. This header mates with 5-row 3M HSHM, UHM, and CP2 Sockets and is end-to-end stackable with 5-row 3M HSHM, HM, and CP2 Headers. It is a module not suitable for stand-alone use, referencing IEC-61076-4-101. Compliance information is available in the Regulatory Information Appendix (RIA) in the "RoHS compliance" section of www.3Mconnectors.com (RIA E1 & C1 apply).
