857-052-558-208

Edgeboard Connectors Overview

The EDAC Inc. 857-052-558-208 is a standard card edge connector designed for panel mount applications. It features a dual female configuration with 52 positions arranged in two rows. The contact spacing is 3.96 mm (0.156 inches), and the row spacing is 5.08 mm (0.200 inches). The connector utilizes gold-plated copper alloy contacts and a black thermoplastic insulator body. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The unit employs a solder lug termination style and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female receptacle design accommodating non-specified board types
• Gold-plated copper alloy contacts for reliable signal transmission
• Low-profile insulator body construction for space-constrained installations
• Panel mount orientation with vertical installation angle

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Communication equipment utilizing standard thickness PCBs
• Medical devices needing high-reliability card edge connections
• Energy sector hardware with specific thermal operating requirements

Edgeboard Connectors Procurement Notes

Verify the exact part number against official EDAC documentation to ensure compatibility with system specifications. Confirm that the required PCB thickness aligns with the 1.57 mm nominal specification. Check current availability status as distribution channels may vary. Ensure that the solder lug termination method matches the assembly process. Validate environmental ratings against operational conditions before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Choose this component when a dual-row, 52-position connection is necessary for panel-mounted architectures. The 3.96 mm pitch suits applications where standard board dimensions are utilized. Consider the gold plating for corrosion resistance in demanding environments. Evaluate the vertical mounting style against spatial constraints within the enclosure. Assess the thermal range suitability for the intended operational climate.

Edgeboard Connectors Part Context

This model belongs to the EDAC 857 series of edgeboard connectors. The series provides standardized solutions for connecting double-sided PCBs to backplanes or chassis. The 857 designation indicates specific mechanical dimensions and contact configurations distinct from other EDAC families like the 305 or 357 series. It represents a specialized variant optimized for particular panel integration needs.
