Technical specifications and performance parameters
Electrical and mechanical characteristics
The XS2R-D422-1 offers precise mechanical and electrical properties suited to rigorous industrial standards. It is rated for a maximum voltage of 250 VDC and 125 VAC, accommodating a current of up to 3 amps. Contact resistance is maintained at a maximum of 40 milliohms, which supports efficient power and signal transfer with minimal loss. The connector exhibits excellent insulation resistance of at least 1000 megaohms at 500 VDC and possesses a dielectric strength of 1500 VAC for 1 minute with leakage current not exceeding 1 mA. This electrical integrity ensures high safety and operational reliability in demanding setups. Mechanically, the connector is designed to withstand up to 200 insertion cycles without degradation, underscoring its durable build in repetitive use scenarios.
Environmental and material properties
The ruggedness of the XS2R-D422-1 is further reinforced by its environmental resistance. It operates efficiently within an ambient temperature range from -25°C to +70°C and maintains functionality with relative humidity between 20% and 85%. This wide operational window makes it adaptable to diverse climates and industrial atmospheres. Constructed from high-quality materials, the pin block is made of polyamide resin, the contacts are brass-based, the fixture is aluminum, and rubber is used for the O-ring seals that guarantee water and dust resistance. The housing itself is fashioned from polybutylene terephthalate (PBT), with a UL94 V-0 flammability rating, ensuring not only longevity but also enhanced safety under thermal stress. The IP67 class protection confirms its suitability for applications involving exposure to contaminants and water immersion.

Design features and installation considerations
Structural design and materials
The XS2R-D422-1 is thoughtfully engineered to meet both functional and environmental demands of professional industrial settings. Its round connector format with M12 threading enables secure and vibration-resistant fastening, critical for maintaining connection integrity. The T-shaped distributor style allows bifurcation of electrical channels, enhancing wiring versatility and reducing complexity in system integration. Material selection plays a key role in the connector’s resilience: the polybutylene terephthalate housing ensures chemical resistance and mechanical strength, while the brass contacts provide reliable conductivity and corrosion resistance. The aluminum fixtures contribute to rigid mechanical stability, and the use of rubber O-rings guarantees waterproof sealing conforming to IP67 standards. The gray color of the housing facilitates visual identification in complex assemblies.
Practical installation and handling guidance
Engineers and installers benefit from the ergonomic design of the XS2R-D422-1, which simplifies installation and maintenance tasks. Its keyed orientation prevents incorrect mating, ensuring safe and straightforward connection assembly. The coupling nut facilitates quick yet firm attachment without requiring specialized tools. Installation in free-hanging or inline positions offers flexibility according to layout requirements. The connector’s durability supports multiple mating cycles, allowing reliable reuse and reducing downtime during equipment upgrades or replacements. Due to its IP67 rating, it is suitable for deployment in challenging environments such as outdoor automation lines or industrial washdowns. When integrating the XS2R-D422-1, careful attention should be paid to aligning the connector properly and tightening to specified torque values to maintain optimal sealing and electrical performance.
