8840/8850/8855 Series
1.27mm 2 Piece I/O Connector
The 88 Series fully utilizes the concept of straight-beam construction with two lateral contact points and offers excellent positioning thanks to a three-sided protective molding; furthermore, as a standard in the field of half-pitch connectors, this series boasts a wide range of variations with proven track records. The 1.27-mm pitch connectors of the 8840/8850/8855 Series provide support for anti-EM interfaces.
As such, they are the ideal choice when aiming to miniaturize devices, carry out highly-dense mounting, or diversify functionality. Please contact your local KEL sales branch should you require any information regarding specifications not included in the current catalog.
