Product Features & Advantages

Optimized High-Density Design: The rectangular layout maximizes the number of contacts per unit area, allowing consolidation of multiple discrete wire connections into a single, manageable interface—ideal for modern PCB Board Relay control panels.
Superior Mechanical Locking: The screw or cam-lock mechanism ensures a secure, vibration-proof connection that will not back out, critical in aerospace and railway applications subject to constant motion.
Excellent EMI/RFI Shielding: The full-metal shell and optional shielded backshells provide outstanding protection against electromagnetic interference, safeguarding sensitive signals to and from components like Solid State Relays and communication modules.
Removable Contact Design: Contacts can be individually inserted and removed, allowing for easy field repair, contact replacement, and wiring configuration changes without replacing the entire connector.
Rugged Environmental Sealing: High-performance gaskets and sealing glands protect the connection from moisture, dust, and fluids, offering reliability comparable to that of a Metal Sealing Relay in harsh conditions.
Polarized and Keyed Design: Incorporates foolproof polarization features to prevent mismating, ensuring correct connection of complex harnesses every time.

Our Manufacturing Advantage: YM applies its extensive expertise in precision metal fabrication and electrical contact technology—honed through manufacturing Polarized Relays and Military Metal Relays—to produce the Y11P-2255ZJ10. This ensures exceptional shell machining accuracy, consistent contact plating quality, and reliable sealing surface finishes.

How to Specify and Install the Y11P-2255ZJ10 Connector

System Interface Definition: Map out all signals and power lines requiring connection. Determine the total pin count and segregate by current level (signal vs. power).
Connector Configuration: Select the appropriate Y11P-2255ZJ10 variant with the required number and type of contacts. Choose the correct backshell and sealing gland for your cable diameter.
Contact Termination: Using calibrated tooling, crimp or solder wires to the removable contacts according to the pin-out diagram. Ensure each contact is fully seated in the connector insert.
Harness Assembly: Route the cable through the backshell and sealing gland. Assemble the insert into the shell housing, install all seals, and tighten the backshell to achieve the proper environmental seal.
Panel Mounting & Final Mating: Mount the connector receptacle to the panel. Align the plug and receptacle using the polarization key, then engage and tighten the locking mechanism (screws or cam) to the specified torque. Perform electrical verification tests.

Production & Quality Control Process

Every Y11P-2255ZJ10 connector is manufactured through a rigorous, controlled process to guarantee performance:

Precision Machining: Connector shells and hardware are CNC machined from certified metal stock, with critical sealing surfaces finished to fine tolerances.
Contact Fabrication & Plating: Contacts are precision stamped and formed, then undergo selective gold or tin plating in controlled baths to ensure optimal electrical performance.
Molding of Insulators: Dielectric inserts and sealing grommets are injection molded from high-grade, flame-retardant thermoplastics and elastomers.
Sub-Assembly & Inspection: Contacts are assembled into inserts. Each sub-assembly is inspected for correct orientation and seating.
Final Assembly & Testing: Complete connectors are assembled. A statistically significant sample from each production lot undergoes full environmental testing (vibration, thermal shock, sealing) and electrical testing (continuity, insulation resistance, dielectric strength).
Traceability & Packaging: All components are traceable. Final products are packaged to prevent damage and include identification labels.

This end-to-end quality assurance, mirroring the standards for our Solid State Relays and other precision components, ensures connectors that deliver reliable performance in critical applications.
