Overview
The Sullins ESM43DRMH (part number 16512-7-1) is a card-edge connector designed for board-level interconnect applications. Sullins Connector Solutions manufactures a comprehensive line of RoHS-compliant edge connectors serving industrial, test, communications, and consumer electronics markets. The ESM43DRMH supports secure solder terminal connections for printed circuit board extensions and board-stacking configurations.
Key Features
- RoHS Compliant: Lead-free design meeting environmental regulations
- Gold-Plated Contacts: 30 microinch selective gold plating over nickel underplate ensures corrosion resistance and reliable signal path
- Phosphor Bronze Contacts: Industry-standard contact material for durability and longevity
- High Current Rating: 3 Amps per contact for typical Sullins edge connector designs
- Solder Terminals: Direct PCB solder connection for permanent assembly
- Multiple Pitch Options: Sullins offers contact center spacing from 0.039″ to 0.156″ to accommodate diverse application requirements
Technical Specifications
The Sullins ESM43DRMH is part of Sullins’ comprehensive edge connector portfolio. Standard specifications for comparable Sullins connectors include contact resistance of 30 milliohms maximum and operating temperature ranges from −65°C to +150°C. Custom high-temperature versions rated to +250°C are available. The connectors support dual-row configuration for board-to-board extensions and accept standard 0.062″ thick PCBs. Plating specifications include 30 microinch selective gold over 50 microinch nickel underplate as standard.
Typical Applications
