JST NH connector (2.5mm pitch, 3A rated current) is widely found in consumer electronic products and industrial appliances due to its extremely compact size (5mm height, 0.5g per port) yet great durability. For example, DJI Mavic 3 UAV uses jst nh to connect the flight control module, enhances harness density by 30%, reduces the whole machine weight by 8g (0.3% of overall weight), and less than 5mΩ for contact resistance deviation in vibration environment of 10G (test requirement MIL-STD-202). In the international market of miniaturized connectors in 2023, jst nh had 25% market share in consumer electronics (Yole data), its SMT welding rate was 99.5% (traditional plug-in 95%), and the cost of a single port was as cheap as 0.08 US dollars (15% cheaper than comparable products).
In industrial automation, jst nh’s working temperature range of -25℃~+105℃ can be applied in harsh environments. For example, Siemens S7-1500 PLC connects to I/O modules through this connector, and saves 40% of wiring time (2 hours to 1.2 hours) with IP67 protection (dust and water proof test standard IEC 60529). ABB statistics show that the failure rate of industrial robots with jst nh is reduced to 0.005 times/k thousand hours (industry standard 0.02 times), and maintenance cost savings per year are $1,200 per unit. Its insertion and extraction life is as high as 50 times (30N contact force test), and the variation in contact resistance after insertion and extraction is less than 10mΩ (industry standard ≤20mΩ).
In car electronics, the jst nh is AEC-Q200 certified (temperature cycle test -40 ° C ~+125 ° C) for on-board sensors such as tire pressure monitoring modules. The Tesla Model Y door control unit uses this connector, which is 50% harness length-saving (2m to 1m), 12% resistance loss-saving, and 0.8W power consumption-saving. Car connectors market size is 8.5 billion US dollars in 2023, jst nh is 8% (Strategy Analytics statistic), and it’s suitable for use in high-voltage electric vehicle environments (800V system) by possessing nice salt spray resistance performance (change of impedance ≤3% at 96-hour test).
As jst nh has low-power design (≤15mΩ contact resistance) in iot devices, it can be better energy efficient. Huawei Watch 4 Pro smartwatch employs this connector to interface battery and motherboard, reducing the standby current to 2μA (industry rival 5μA), and extending the battery life to 21 days (industry average 14 days). In 2022 worldwide IoT device shipments, jst nh penetration was 18% (Counterpoint data), with capability to support 0.5A~3A dynamic current loads and to handle the sensor data sampling rate (100Hz~1kHz).
Typical uses are a 2-week motherboard assembly delay of the 2021 SONY PS5 due to jst nh supply shortage, showing the criticality of its supply chain. Further, MIT’s 2023 study proved that productivity of assembly of modular robots using this connector was improved by 22% (error rate reduced from 3% to 0.8%). From cost savings (per unit: $0.06 when purchased in bulk) and reliability (MTBF 100,000 hours) to miniaturization (40% smaller than conventional versions), the jst nh is the go-to interconnect solution for high-density electronic system design.
