2-Pole 6.3mm High-Current Terminal Connectors

Achieve secure, high-power electrical connections with durable Terminal Connectors designed for performance and safety in multi-circuit applications. The SH6.3ZC-2NB is a 2-pole (2P) connector with a 6.3mm pitch, engineered for reliable signal and power transmission in compact electronic systems. Widely recognized by its industry equivalent DR250-2C, this terminal block ensures full compatibility with existing designs and global manufacturing standards, making it an excellent choice for replacements, upgrades, and new production runs in industrial and consumer electronics.

Constructed from PA66 UL94V-2 flame-retardant nylon, the insulating housing delivers superior thermal stability, mechanical strength, and fire resistance. The UL94V-2 rating ensures the material will self-extinguish within seconds if exposed to flame, significantly reducing fire hazards in enclosed or high-temperature environments such as control panels, power supplies, and household appliances.

This high-performance connector supports a maximum voltage of 250V AC/DC and a current rating of up to 12A per contact, making it ideal for medium-power circuits that demand stable conductivity and minimal heat buildup. Whether used for dual-channel power delivery, relay connections, or sensor wiring, the SH6.3ZC-2NB provides consistent performance under continuous load.

The connector features solder tabs and internal pins made from tin-plated brass, ensuring excellent electrical conductivity, corrosion resistance, and long-term reliability. The tin plating enhances solderability and prevents oxidation, while the brass material provides mechanical resilience and low contact resistance.

Designed for wire sizes from 24 AWG to 14 AWG, this terminal accommodates a wide range of wire gauges, offering flexibility in wiring configurations. Its compact 2-pole design allows for space-efficient PCB mounting, making it suitable for densely populated boards where reliable dual-circuit connectivity is required.

Common applications include HVAC controls, industrial automation, lighting systems, kitchen appliances, and power distribution modules.
