JST SH is a 1mm pitch high-fineness wire-to-board connector of 1A current and is widely used in miniature electronic devices. In consumer electronics, the weight (3.0mm thickness) and weight (0.3g for single-port) advantages are enormous: e.g., DJI Mavic 3 drone uses jst sh to supply power to flight control unit, packing density increases by 40%, and total machine weight is reduced by 15g (0.5% of total machine weight). 2023 Market size of $2.4 billion, JST SH market share of around 18% (Yole data), driven mainly by its SMT (surface mount) process capability, 99.8% yield in welding (97% for conventional connector), production cost lowered by 30% ($0.05 in single-port cost).
In medical devices, jst sh supports the IEC 60601-1 safety standard, is 1000 insertions survivability (life test variation ±3%), and is applied to portable monitors. For example, Philips Tempus ALS ventilator uses this connector to achieve 50% less maintenance time (2 hours saved to 1 hour). Its operating ambient temperature range (-25℃ to +85℃) can resist high temperature sterilization process (change of contact resistance ≤0.1Ω in 134℃ steam environment), and its failure rate is less than 0.01 times / 1000 hours (industry average 0.05 times).
Industrial automation is dependent on vibration resistance of jst sh (change in contact resistance ≤5mΩ at 10-2000Hz /10G acceleration). Mitsubishi FX5U PLC combines I/O modules and the connector to ensure 60% wiring space savings and instant current support up to 1.5A (peak load capability 20% higher than industry standards). Micro connector control cabinet failure rate decreases by 12% based on ABB statistics, and maintenance dollars saved annually up to $800/unit.
Minimum power consumption of jst sh (contact resistance ≤20mΩ) ensures maximum energy efficiency for iot applications. For example, the Apple AirTag uses this connector to join the CR2032 battery and the PCB, and standby current is 1μA (5μA in typical solutions), and battery life is up to 1 year (9 months average on competing products). In 2022, global demand for IoT connectors went up by 23%, of which wearable device penetration contributed 34% (Counterpoint data), Huawei Watch GT 4 as it applied the connector to minimize the device thickness to 7mm (industry norm 9.5mm).
Automotive electronics: new market: jst sh is AEC-Q200 qualified (-40 ° C to +125 ° C) for in-car sensors like tire pressure monitoring modules. The connector is employed in the Tesla Model 3’s seat control unit, and the failure rate is reduced to 0.003 times/year (0.01 times in the traditional FPC solution). Its salt spray resistance (impedance change ≤3% after 48-hour test) ADAPTS the corrosive conditions of electric vehicles, and on-board micro-connector market size will reach 720 million US dollars in 2023, and jst sh will account for 12% (Strategy Analytics data).
Time-honored applications are SONY PS5’s 15% cut in production capacity in 2021 due to a jst sh shortage of supply, a time-honored example of the vital role it plays in the supply chain. The MIT research in 2023 also found that assembly efficiency of modular robots with the connector improved by 27% (error rate reduced from 5% to 1.2%). From cost and reliability to miniaturization, jst sh is now a mission-critical interconnect solution for high-density electronics.
