ERNI SMC Product Catalog

Product catalog summary
General Overview: The SMC 1.27 mm connectors are engineered for modern electronic systems, offering compact, secure, and reliable connections with high signal integrity and current-carrying capacity. They feature double-sided spring contacts, high-temperature resistant insulators, and high mating reliability, supporting data transmission rates up to 3 Gbit/s.
Features: These connectors are available in various pin configurations (12 to 80 pins) and support SMT and Pressfit termination technologies. They are suitable for board-to-board and wire-to-board connections, available in both male and female versions, and offer lockable and pressfit options.
Capabilities: The connectors support configurations such as stacked (Mezzanine), orthogonal, and coplanar board-to-board connections, as well as pluggable and permanent wire-to-board connections.
Contact Design: Featuring ultra-reliable dual-beam female contacts, twisted contact tulips, and wide contact surfaces, these connectors ensure secure mating and low contact resistance. Polarization and insertion chamfers prevent mismating.
Soldering and Assembly: Designed for robust soldering with high retention forces, the connectors can withstand mechanical stress, shock, and vibration. They support fully automatic assembly and reflow soldering processes.
Technical Data: Operating within a temperature range of -55 to 125°C, the connectors support a current rating of up to 1.7 A per contact and meet various IEC standards for dielectric strength, contact resistance, and vibration resistance.
High-Speed Data Transmission: Suitable for unshielded high-speed applications, SMC connectors support secure data transmission rates up to 3 Gbit/s with a continuous impedance profile.
Ordering Information: The catalog provides detailed ordering information for right angle male and female connectors, vertical male connectors, and vertical male pressfit connectors, including part numbers and packaging options.
Specifications:
  • Vertical Female Connectors: Available in three stacking heights (6.25, 9.05, 13.65 mm) with tape and reel packaging. Part numbers are provided for each configuration.
  • Right Angle Male/Female with Locking System: Features two types of interlocking (positive and friction lock), SMT termination, and data rates up to 3 Gbit/s. Part numbers are listed for different configurations.
  • Board-to-Board Adapter: Supports parallel PCB distances of 20-40 mm, with single-sided locking. Moulded versions offer improved environmental resistance.
  • Board-on IDC: Provides permanent wire-to-board connections with SMT and IDC termination, supporting data rates up to 3 Gbit/s.
  • Cable Assemblies: Includes IDC female connectors with ribbon cable options (standard PVC, high temperature TPE-S, halogen-free TPE-O) and various configurations.
Dimensional Drawings: The document includes detailed dimensional drawings for each product type, specifying measurements for different numbers of contacts.
Key Features:
  • Automated board assembly for all connectors.
  • Location pegs for precise board placement.
  • Black insulation body for easy visual recognition.
  • Data rates up to 3 Gbit/s for connectors with locking systems.
Contact Information: The document provides contact details for ERNI Electronics offices in Europe, North America, Asia, and Switzerland.

ERNI SMC Product Catalog-2

SMC - 1.27 mm Connectors DUAL ROW CONNECTOR Small Grid, Big Possibilities Limited space and high performance demands are characteristics of many modern electronic systems, all of which the connectors must accommodate. There is a corresponding demand for compact, secure, and reliable connectors, with high signal integrity and a relatively high current-carrying capacity. The comprehensive SMC range helps meet these requirements. The high-performance SMT connectors come in a number of different designs, heights, and contact densities in a 1.27 mm grid. The basic design criteria for the SMC series...
