ASM28DSEF

Edgeboard Connectors Overview

The ASM28DSEF is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 56 contacts arranged in two rows with a 0.156-inch pitch. The connector utilizes beryllium copper terminals with gold plating and a polybutylene terephthalate insulator. Designed for panel mounting, it supports signal currents up to 3A and operates within a temperature range of -65°C to 150°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified dual-edge cards
• Panel mount installation with top mounting openings
• Gold-plated beryllium copper contacts for reliable signal transmission
• High-temperature resistant polybutylene terephthalate insulator

Edgeboard Connectors Applications

• Industrial control systems requiring high-temperature stability
• Telecommunications equipment interfaces
• Computing hardware backplane connections
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix requirements against your design specifications, as variants like ASM28DSEF-S13 may differ in locking mechanisms or physical dimensions. Confirm that the 0.156-inch pitch and 0.062-inch card thickness align with your PCB edge guide constraints. Ensure compliance with RoHS3 standards if required by your project regulations before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-temperature connection is needed for dual-edge cards. The beryllium copper material offers superior spring properties compared to phosphor bronze. Verify that the panel mount style fits your enclosure design, as through-hole options exist in the same family but require different mechanical integration strategies.

Edgeboard Connectors Part Context

This part belongs to the ASM series of edgeboard connectors from Sullins Connector Solutions. It shares the 56-position layout and 0.156-inch pitch with related models such as HSM28DSEF and ESM28DSAS. Key distinctions include its specific panel mount orientation and operating temperature rating, which differentiate it from standard surface-mount or lower-temperature variants in the product catalog.

Edgeboard Connectors Replacement Considerations

Direct substitutes include HSM28DSEF and ESM28DSAS, provided mechanical mounting differences are addressed. HSM28DSEF shares identical electrical parameters but requires panel mounting verification. ESM28DSAS offers right-angle through-hole mounting. Ensure card thickness compatibility across all potential replacement candidates.
