1561267-2

Overview

The 1561267-2 is a high-density differential array plug connector manufactured by TE Connectivity AMP Connectors, belonging to the STEP-Z series. Designed for surface mount technology (SMT), this component features a 104-position configuration arranged in a single row with a 0.051-inch (1.30mm) pitch. It utilizes gold-plated contacts to ensure reliable signal integrity and low contact resistance in demanding environments. The connector supports mating stack heights of 17mm, 23mm, or 27mm, providing flexibility for board-to-board interconnections. With a board height of 0.510 inches (12.95mm), it accommodates specific mechanical constraints while maintaining robust electrical performance.

Feature Summary

• High-density differential array design supporting 52 pairs of signals within a compact footprint
• Gold-plated contact surfaces engineered for superior conductivity and corrosion resistance
• Surface mount construction optimized for automated assembly processes
• Flexible stack height options accommodating varied board thickness requirements

Applications

• High-speed data transmission systems requiring differential signaling
• Server and storage backplane interconnects
• Telecommunications infrastructure equipment
• Industrial control systems with dense I/O requirements

Procurement Notes

Verify component authenticity through authorized TE Connectivity distributors. Confirm RoHS compliance status as documentation indicates non-applicable classification. Check for obsolescence notices or product change notifications prior to procurement. Ensure storage conditions meet moisture sensitivity level 1 requirements to prevent soldering defects during reflow.

Selection Notes

Select this connector when high pin count differential signaling is required in a surface mount form factor. Evaluate mechanical clearance against the specified 0.510-inch board height. Consider the 0.051-inch pitch for trace routing density. Verify mating compatibility with corresponding receptacle components from the same STEP-Z series family.
