2P 6.3mm High-Power Terminal Connectors

Engineer superior electrical performance with high-capacity Terminal Connectors built for demanding power applications. The SH6.3ZC-2PD is a 2-pole (2P) connector with a 6.3mm pitch, designed to deliver robust and reliable connectivity in high-current circuits. Widely recognized by its industry-standard equivalent 50016HS-1, this terminal block ensures seamless compatibility with existing systems, making it a trusted choice for industrial equipment, power tools, and advanced consumer electronics.

Featuring a housing made from PA66 UL94V-0 flame-retardant nylon, the SH6.3ZC-2PD offers the highest level of fire resistance available in standard connector materials. The UL94V-0 rating indicates that the material extinguishes within 10 seconds after flame removal and does not drip flaming particles—providing critical safety in enclosed or high-temperature environments where fire hazards must be minimized.

This high-performance connector is rated for up to 300V AC/DC and an impressive 18A per contact, significantly exceeding standard 12A terminals. This makes it ideal for heavy-duty applications such as motor drives, power inverters, heating systems, industrial controls, and high-wattage lighting where sustained power delivery and thermal stability are essential.

The internal contacts are precision-made from brass and phosphor bronze, both plated with tin to ensure excellent conductivity, low contact resistance, and resistance to oxidation and fatigue. Phosphor bronze offers superior spring characteristics, maintaining firm contact pressure over time and under repeated mating cycles.

Supporting wire sizes from 24 AWG to 12 AWG, this terminal accommodates a wide range of conductor gauges, including thicker wires used in high-power circuits. Its solder-tab design enables secure and permanent mounting on PCBs, ensuring mechanical stability and reliable electrical performance even under vibration and thermal stress.

Common applications include HVAC systems, industrial automation, power supplies, kitchen appliances, and automotive power modules.
