Y50X12-10ZK10-2WL2 Mechanical Architecture of the Square Flange Receptacle
Он Y50X12-10ZK10-2WL2 is a precision-engineered receptacle designed for panel-mount applications where a stable and secure interface is required. The size 12 shell is a mid-range compact housing that efficiently accommodates 10 independent electrical channels. The square flange (ZK10) design provides a large surface area for secure mounting to equipment chassis or control panels, distributing mechanical stress evenly across the mounting hardware. This ensures that the connector remains immobile even when subjected to high-frequency vibrations or the mechanical torque of frequent mating cycles.
The primary locking interface utilizes the standardized three-point bayonet coupling system. This mechanism allows for rapid connection with a matching plug through a 120-degree rotation, providing tactile and audible feedback when the lock is fully engaged. The inclusion of the 2WL2 backshell adds a critical layer of protection for the rear of the receptacle. This backshell provides a secure cable entry point and integrated strain relief, protecting the internal solder or crimp terminations from being compromised by mechanical pulling or bending within the equipment housing.

10-Socket Layout and Signal Integrity
The 12-10 insert arrangement of the Y50X12-10ZK10-2WL2 offers high contact density within a compact footprint. The ZK designation—identifying socket (female) contacts within the receptacle—is a critical safety choice, particularly for power-output or signal-source interfaces. By housing the conductive elements deep within the dielectric insulator, the risk of accidental short-circuits or electrical shock during maintenance is minimized. Each socket is machined from a high-conductivity copper alloy and finished with premium gold plating, ensuring low contact resistance and excellent protection against atmospheric oxidation.
Internal insulation is managed by high-grade dielectric polymers that offer superior insulation resistance and thermal stability. These materials prevent electrical leakage between the ten closely spaced contacts, even in environments with high humidity or electrical noise. For engineers designing multi-channel sensor arrays or digital logic control panels, the Y50X12-10ZK10-2WL2 provides a dependable gateway that maintains signal purity and prevents crosstalk across all ten poles.
Environmental Hardening and EMI Protection
As an environmental-grade (X series) connector, the Y50X12-10ZK10-2WL2 is designed to maintain system integrity in harsh conditions. It is equipped with a comprehensive sealing system, including internal grommets and high-resilience gaskets that create a moisture-proof and dust-proof barrier when mated with a compatible plug. This ensures that the internal contact area remains protected against rain, salt spray, and industrial contaminants. The 2WL2 backshell provides additional sealing at the rear, preventing moisture from entering the equipment through the cable exit.
The metallic aluminum alloy shell also provides an effective Faraday cage for EMI/RFI shielding. When the receptacle is properly grounded to a conductive panel and used with shielded cables, the Y50X12-10ZK10-2WL2 effectively attenuates external electromagnetic noise. This is a vital requirement for sensitive electronics operating in “noisy” industrial environments or near radio communication equipment. The shell finish—typically nickel or olive drab—provides a robust layer of corrosion resistance, preserving the functional life of the bayonet lugs and the structural integrity of the connector.

Strategic Integration in Industrial and Aerospace Grids
The versatility of the Y50X12-10ZK10-2WL2 makes it an essential component for engineers across the aerospace, defense, and industrial automation sectors. In the aerospace sector, its lightweight and rugged square-flange design is highly valued for avionics control boxes and ground support equipment where space is at a premium but reliability is non-negotiable. The 10-socket layout allows for complex signal routing while the bayonet lock ensures mission-critical data remains uninterrupted.
In industrial automation and energy grids, this receptacle is frequently used as the primary interface for control panels and mobile monitoring devices. The 2WL2 backshell ensures that the rear cable connections survive the mechanical stress associated with field assembly and maintenance. By providing a standardized, GJB-compliant, and cost-effective interconnect gateway, the Y50X12-10ZK10-2WL2 delivers the reliability required for the most demanding electronic environments worldwide.
Часто задаваемые вопросы
What does the ZK10-2WL2 designation signify?
What does the ZK10-2WL2 designation signify?
ZK10 refers to a square flange receptacle with socket (female) contacts, while 2WL2 indicates a specific straight environmental backshell that provides sealing and strain relief for the cable.
Why use sockets (ZK) in a panel-mounted receptacle?
Why use sockets (ZK) in a panel-mounted receptacle?
Using socket contacts in a receptacle is a standard safety measure for power-output or signal-source panels, as it protects the conductive elements from accidental contact or short circuits when the connector is unmated.
Is this model intermateable with all Y50 size 12-10 plugs?
Is this model intermateable with all Y50 size 12-10 plugs?
Yes, it is designed to mate with any Y50 series plug that features a size 12 shell and a matching 10-pin (male) contact arrangement, regardless of the plug’s backshell type.
How does the 2WL2 backshell improve the connection?
How does the 2WL2 backshell improve the connection?
The 2WL2 backshell provides a secure mechanical clamp on the cable entering the rear of the receptacle, protecting the internal wiring from strain and enhancing the moisture seal of the equipment chassis.
