0.3 mm-spacing shielded FPC connector
EN-31 series, developed

We are pleased to announce the development and commencement of marketing of a 0.3 mm-spacing shielded FPC connector, the EN-31 series, which is capable of fast transmission. Its specifics are given below.

It has been noticed in the market that as DVCs and DSCs went higher in image quality and performance, the signal transmission speed has become faster. In connection with growing requirements toward higher transmission speed for connectors for internal connection, coaxial connectors for extra fine cables are used for connection of an image pick-up element, LCD panel and main PCB.

Leading at the forefront of the industry, we have brought forward a suggestion that coaxial connectors for extra fine cables to be replaced with shielded FPCs, and developed this product. This new product’s performance is equally high to that of connectors for extra fine cables, and capable of fast signal transmission.

This connector is covered with a metal shield, and its shielding performance and connector rigidity thus improved ensure high level contact reliability. Combined use of this connector with a shielded FPC will enhance grounding performance of both an FPC and connector, and make counter-EMI performance more effective.

With contacts being of an N-ZIF structure, FPCs can be inserted simply with one action. Further, a mechanism by the use of our exclusive lever structure [patent pending] is featured for FPC fall-out prevention. Its 0.3 mm-spacing and a low 1.2 mm profile when mounted will prove this connector to be a good contributor for even smaller and thinner equipment design.
