Additionally, the temperature range, observed in some listings as -25°C to +105°C, is a critical factor for applications in extreme environments. Misalignment in electrical specifications can lead to system failures, safety hazards, or inefficient operation, making it essential to validate these parameters with the supplier before finalizing any purchase order.

Dimensional and physical attributes also require rigorous verification to ensure proper integration into the final product. The observed product size of 805514mm and single package size of 8X5.5X1.4cm provide a baseline for spatial planning, but buyers must confirm if these dimensions are consistent across all units or if custom sizes are available. The housing material, often ABS or PA66, impacts durability and aesthetic appeal, while the shape, whether round or rectangular, affects installation compatibility. Buyers should request detailed technical drawings and material certifications to ensure that the physical characteristics of the lock meet the mechanical and environmental demands of the intended application.

Compliance and Safety Documentation

Compliance with international safety and environmental standards is non-negotiable for electric locks, particularly those used in consumer-facing or industrial applications. Buyers must verify that suppliers hold relevant certifications, such as CE, ISO, UL, and RoHS, which attest to the product's adherence to safety, electromagnetic compatibility, and environmental regulations. The observed mention of certifications like "Ce ISO and So on" indicates that some suppliers may have multiple credentials, but buyers should request specific certificate numbers and validity dates to ensure authenticity. Non-compliant products can lead to legal liabilities, market access restrictions, and reputational damage, making certification verification a critical step in the sourcing process.

Environmental and operational safety standards also play a crucial role in product selection. For instance, the observed environmental rating of less than 250°C suggests specific thermal limitations that must be considered for high-temperature applications. Buyers should inquire about the testing procedures used to validate these ratings and request test reports from accredited laboratories. Additionally, understanding the warranty terms, observed as 1-2 years for some products, provides insight into the manufacturer's confidence in their product's longevity. A robust warranty policy can mitigate risks associated with early failures, but buyers should clarify the scope of coverage and the process for claiming warranty services.
