WY Series Connectors: Bayonet Waterproof Solutions for Test & Measurement Equipment
The WY series connectors, a signature metal waterproof line, are engineered to deliver reliable connectivity for test & measurement (T&M) equipment in demanding environments. Featuring bayonet coupling for quick, anti-vibration mating and IP55 to IP67 protection, these connectors excel in benchtop instruments, portable field testers, multi-channel data acquisition systems, and industrial automation test rigs. Compliant with RoHS2 standards, they combine precision electrical performance, durable construction, and flexible configurations—including full core size options and multi-pin selections-to meet the strict stability and accuracy requirements of T&M applications.
Full Core Size Specifications of WY Series
The WY series covers 8 core shell sizes, categorized by panel cutout diameter (16mm to 55mm), each optimized for specific T&M signal and power needs. Larger shell sizes support higher pin counts and current ratings, enabling seamless integration with diverse test setups:
WY16: 16mm panel cutout, ideal for compact handheld testers and low-density signal links (e.g., temperature sensor connections).
WY20: 20mm panel cutout, a versatile size for mid-range T&M equipment, balancing space-saving design and multi-channel connectivity.
WY24: 24mm panel cutout, including the WY24 Data variant (24.5mm cutout) that supports hybrid connections (LC, RJ45, USB 3.0, HDMI 2.0) for high-speed data transmission in T&M systems.
WY28: 28mm panel cutout, suited for high-current T&M applications (e.g., power supply testing) with support for larger contact diameters.
WY32: 32mm panel cutout, designed for high-density multi-channel test rigs, offering a balance of pin count and mechanical stability.
WY40: 40mm panel cutout, ideal for complex test systems requiring both high-current power and multi-signal transmission.
WY48: 48mm panel cutout, for ultra-high-density applications like semiconductor test modules and automated production line testers.
WY55: 55mm panel cutout, the largest size for heavy-duty T&M setups, supporting maximum current (up to 150A) and pin count (up to 61 pins).
Flexible Multi-Pin Configurations
Each WY series size offers 2 to 61 pin options, with pin count tailored to shell capacity, ensuring precise matching to T&M equipment requirements. Pin configurations align with common test scenarios: 2-10 pins for basic sensor links, 12-31 pins for multi-channel data acquisition, and 38-61 pins for complex signal switching matrices and high-density test modules.
Core Performance Advantages
Performance for T&M Equipment
1. Secure Bayonet Coupling & Anti-Vibration 120° quick bayonet locking ensures tool-free mating with audible confirmation, rated for over 500 mating cycles. The zinc alloy shell (chrome-plated) enhances structural rigidity, resisting vibration in mobile test equipment and industrial environments—critical for uninterrupted T&M operations.
2. Precision Electrical Performance Gold-plated brass contacts deliver contact resistance as low as 0.5mΩ (for 3.5mm contacts), minimizing signal attenuation for low-current and high-frequency testing. Insulation resistance ≥2000MΩ (DC 500V), rated voltage up to 500V AC, and test voltage up to 1500V AC (1 minute) prevent signal leakage, ensuring measurement accuracy.
3. Broad Environmental Adaptability Operating temperature range of -40°C to +85°C, with PPS insulation (max 260°C resistance) for thermal stability. Protection levels from IP55 (dustproof) to IP67 (waterproof) shield against dust, moisture, and temporary water immersion, suitable for laboratory, industrial, and outdoor field testing.
4. Versatile Current Handling Rated current ranges from 5A to 150A, depending on contact diameter (1mm to 3.5mm) and shell size—supporting both low-power signal sensors and high-current power supply testing in T&M systems.
5. Compliance & Durability RoHS2 compliant, with all models undergoing rigorous factory testing for insulation, contact resistance, waterproofing, and mating durability. Compatible with matching cable glands (nylon/metal, PG/M/NPT threads) for strain relief and enhanced EMI shielding.
