857-030-521-103

Edgeboard Connectors Overview

The EDAC Inc. 857-030-521-103 is a high-temperature card edge connector receptacle featuring 30 positions in a dual configuration. It utilizes a 0.156-inch (3.96 mm) contact spacing and supports board thicknesses of approximately 1.57 mm. The unit employs gold-plated copper alloy contacts with wire wrap termination for secure electrical connections. Designed for panel mount installation at a vertical orientation, the housing is constructed from polyphenylene sulfide to withstand elevated operating temperatures. The component is rated for 5 A current and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• High-temperature resistant polyphenylene sulfide insulation material
• Wire wrap termination method for reliable circuit attachment
• Vertical panel mount design for space-constrained enclosures

Edgeboard Connectors Applications

• Industrial control systems requiring thermal stability
• High-temperature electronic assemblies
• Panel-mounted interface modules

Edgeboard Connectors Procurement Notes

Verify that the target application environment exceeds standard temperature limits, as this model is specifically designated for high-temperature service. Confirm that the printed circuit board thickness aligns with the specified 1.57 mm requirement to ensure proper mechanical engagement. Ensure the system design accommodates wire wrap termination processes rather than surface mount or through-hole soldering methods.

Edgeboard Connectors Selection Notes

Select this component when standard connectors fail under thermal stress. The polyphenylene sulfide housing provides superior heat resistance compared to common thermoplastics. Verify compatibility with wire wrap tools and pins during the design phase. Consider the vertical profile for panel integration constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 857 series, which specializes in high-temperature card edge connectors. The series offers various position counts and mounting options tailored for demanding environments where standard connectors are insufficient. The 857 series distinguishes itself through specialized materials and termination styles suitable for rigorous industrial applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 857-030-445-108 and 857-030-521-103 variants with different suffixes. Verify that any replacement maintains the high-temperature rating and wire wrap termination capability. Cross-reference pin count and spacing to ensure mechanical fit.
