ASM25DRXI

Edgeboard Connectors Overview

The ASM25DRXI is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 50 positions arranged in two rows of 25 contacts each, with a contact pitch of 0.156 inches (3.96 mm). The connector accommodates a PC board thickness of 0.062 inches (1.57 mm) and utilizes full bellows contact types for reliable engagement. The insulator material is polyphenylene sulfide (PPS), providing durability across an operating temperature range of -65°C to 150°C. The contacts are made from beryllium copper and feature a gold surface finish with a thickness of 10.0 µin (0.25 µm).

Edgeboard Connectors Feature Summary

• Full bellows contact design ensures secure mating with dual-edge cards.
• Polyphenylene sulfide (PPS) insulation offers high thermal stability.
• Gold-plated beryllium copper contacts provide corrosion resistance.

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge connections.
• Telecommunications equipment utilizing standard 0.156 inch pitch boards.
• Automotive electronics modules needing wide temperature tolerance.

Edgeboard Connectors Procurement Notes

Verify the specific suffix designation against official Sullins documentation to confirm exact termination style and mounting flange configuration. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm that the gold plating thickness meets the required signal integrity standards for the application environment before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 0.156-inch pitch is required. The PPS insulator and beryllium copper contacts support high-temperature environments up to 150°C. Ensure the design accommodates the specific mechanical dimensions and locking features associated with the ASM25 series family.

Edgeboard Connectors Part Context

This part belongs to the ASM25 series of card edge connectors from Sullins Connector Solutions. The series is characterized by its use of polyphenylene sulfide insulation and full bellows contact styles. It is designed for through-hole or specialized mounting applications involving dual-edge circuit boards.

Edgeboard Connectors Replacement Considerations

Cross-reference with other Sullins ASM25 variants such as ASM25DSAI or ASM25DRTI-S13 for mechanical fit. Verify that alternative parts maintain the same 0.156-inch pitch and 50-position count. Confirm that the replacement matches the specific termination and flange requirements of the assembly.
