Import 5.00mm Pitch Spring Clamp Terminal Block — Buy in wholesale FOB from Supplier in United States

This 5.00mm pitch spring clamp terminal block from Dongguan City Aosi Electronics.,ltd is designed for industrial electrical distribution and control applications. The 5.00mm pitch dimension defines the centre-to-centre spacing between adjacent conductive paths, accommodating conductor cross-sections common in 300V to 600V rated installations. Configurations range from 2-pole to 24-pole variants, allowing modular assembly for differing circuit counts. The spring clamp termination method uses a pre-loaded spring element to maintain contact force without screw tightening, reducing installation time and eliminating torque-related failure modes.

The housing material is not specified in the source data, though typical 5.00mm pitch terminal blocks in this class use UL94 V-0 rated polyamide 6.6 (PA66) for the insulating body, with tin-plated brass or copper alloy for the conductive elements. Spring clamps in industrial terminal blocks typically apply a contact force of 10N to 15N per conductor to maintain stable resistance below 5 milliohms under vibration. The design targets DIN rail mounting compatibility, with standard 35mm top-hat rail adherence typical for this form factor. Temperature ratings for comparable products usually span -40 degrees Celsius to +105 degrees Celsius depending on certification level.

Primary buyers include panel builders, automation system integrators, and OEMs in manufacturing, automotive, and electronics sectors. Applications extend to motor control centres, PLC I/O modules, power supplies, and building automation controllers. The spring clamp mechanism particularly suits applications with vibration exposure or where maintenance access is limited. Buyers should confirm current rating per pole, voltage rating, wire stripping length, and whether the 2p to 24p range shares a common housing profile for uniform panel layout. Certification status for UL, CE, or IEC standards is not stated and must be verified directly with the supplier.

Dongguan City Aosi Electronics.,ltd lists an address at Chenwu Community, Houjie Town, Dongguan, Guangdong, China, postal code 523000, though the origin country field states United States. This geographic discrepancy requires direct clarification from the supplier, whether the United States designation refers to a US sales office, a registered US entity, or an error in the platform record. The supplier holds Harbor trust tier status with 0.00% response rate and zero recorded response hours, suggesting limited or no platform-mediated communication history.

The source description contains claims of ISO and CE certification compliance, flexible MOQs, and FOB and CIF shipping terms, though these are presented in generic marketing language rather than verified credentials. No specific certification numbers, accredited bodies, or scope statements are provided. The actual manufacturing location, production capacity, and quality system scope are not independently verifiable from the supplied data. Buyers should treat all compliance claims as requiring documentary evidence before design approval or shipment release.
