345-118-500-208

Edgeboard Connectors Overview

The EDAC Inc. 345-118-500-208 is a standard card edge connector designed for dual-edge mating applications. It features 118 positions with a 0.100-inch (2.54mm) contact pitch and 0.200-inch row spacing. The unit accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Constructed with copper alloy contacts, it offers gold plating on the mating area and tin plating on tails with nickel underplating. The connector supports a current rating of 3 amps and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified board types
• High-profile thermoplastic polyester insulator body
• Copper alloy contacts with gold plating on mating surfaces
• Supports panel mount installation with flush or offset lugs

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules
• Computer peripheral interface connections

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 118-position count and dual-edge specification. Confirm compatibility with 0.062-inch PCB thickness standards. Ensure the gold plating requirement aligns with signal integrity needs. Check RoHS compliance status against project environmental regulations before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when high-density I/O is required in a vertical mounting configuration. The 0.100-inch pitch allows for substantial pin counts within limited board areas. Consider the 3-amp current rating for power distribution capabilities. Evaluate the available mounting options, such as flush or offset lugs, to ensure mechanical stability within the target enclosure design constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 345 series of standard card edge connectors. The series provides various position counts and termination styles to accommodate diverse electronic assembly requirements. The 345-118-500-208 variant specifically addresses high-pin-count applications requiring reliable dual-edge connectivity with robust mechanical locking features.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include other 345-series variants with matching 118 positions and dual-edge specifications. Verify identical pitch dimensions and PCB thickness tolerances. Cross-reference mounting hole patterns and lug configurations to ensure mechanical interchangeability without redesigning the host board layout.
