Available quantities to match your project: order 1, 5, or 50 pieces to suit prototyping, small runs, or larger deployments while controlling cost and inventory. Sealed, waterproof construction: protects sensitive PCB needle-base connections from moisture, dust, and other environmental influences. This reduces failure rates and extends service life in exposed or variable conditions. Purpose and function: designed to provide a reliable, protected interface for PCB-mounted needle base assemblies, enabling secure electrical connections and simple installation without additional sealing work. Compatibility: explicitly compatible with PCB needle base models 776262-1, 776266-1, and 776273-1, allowing plug-and-play integration with those specific bases and minimizing fitment issues. Performance and reliability: the sealed design preserves electrical integrity and reduces maintenance needs. Ideal where consistent contact and environmental protection are required. Practical applications: 1. Outdoor sensor or telemetry modules where boards are exposed to moisture and need a sealed connection to maintain uptime. 2. Industrial control assemblies in manufacturing or processing environments where dust and splashes can cause intermittent faults. 3. Prototype and small-batch electronics using compatible PCB needle bases that require a durable, ready-made sealing solution for testing and early production. Ordering and use notes: choose the quantity that matches your budget and production stage. The product is intended for direct use with the specified PCB needle base models (776262-1, 776266-1, 776273-1); verify compatibility with your board layout before purchase. This product gives you a straightforward way to protect PCB needle-base connections, simplify integration with the listed models, and reduce field failures in challenging environments.
