Customer case for the 24W7 high-current dsub connector with a 90° bend/folding feature, mixed packaging of 17+7 units, and a current range of 10–40A.
New energy storage equipment (a storage power supply manufacturer in Wuhan).
Challenges: The cabinet’s space is compact, and 90-degree wiring requires saving horizontal space. The energy storage units require high currents (30A/channel) and mixed signal transmission. Long-term vibration can cause them to loosen and generate heat.
Solution: Utilize the bent 24W7 female d connector (90° bent plug-in board), featuring 17 signal pins + 7 large-current pins (30A/pin), gold-plated contacts, and a metal shield casing. The product is IP67-rated and suitable for outdoor/harsh environments.
Benefits: – Space utilization increased by 40%, perfectly suited for narrow cabinet cabling.
Continuous operation for 12 months without heat generation or loosening; contact resistance remains stable at <25mΩ.
The lifespan of plug-and-play operations is ≥1000 times, resulting in a 60% reduction in maintenance costs.
Industrial Automation Equipment (Shenzhen Motion Control Equipment Factory)
Pain points: The original, generic DB25 interface has inadequate current capacity (≤5A), is prone to oxidation, has a bit error rate of 3.7%, experiences daily downtime for inspections, and is inefficient.
Solution: Replace with a bent 24W7 socket (90° welding wire type), 7-pin high-current (20A/pin) power supply, 17-pin signal transmission, nickel base with gold plating (60–100μ”), corrosion-resistant, low impedance.
Results: The error rate of the equipment dropped to 0.2%, and the frequency of downtime for maintenance decreased by 76%.
The anti-oxidation capability of the contacts has been enhanced, resulting in three months without routine inspections and significantly improved stability.
The 90° bend adapter allows cables to be routed along the side of the equipment, keeping the wiring tidy and reducing damage from cable bending.
