Frequently Asked Questions
What is the functional advantage of a Reverse Sinking Mount (Mid-Mount) H1.60mm DC jack with a beveled interface?
The mid-mount design drops the connector body into a board cutout to achieve a minimal 1.60mm profile height, while the beveled mouth acts as a lead-in chamfer to facilitate blind-mating and reduce pin wear.
What are the critical PCB cut-out tolerances and pad dimensions for mounting this connector?
The PCB requires an 8.90mm wide by 6.90mm deep edge slot accompanied by four 2.10mm x 1.50mm pads, with layout tolerances maintained within ±0.05mm to ensure correct reflow coplanarity and shear strength.
What contact and housing materials are used to ensure soldering integrity and long-term durability?
The jack uses a UL 94V-0 black PA10T thermoplastic housing designed for high-temperature reflow soldering, paired with gold-plated copper alloy contacts and shell for corrosion resistance across -55°C to +105°C.
What electrical and cycle life ratings qualify this jack for industrial power input?
It is rated for 24V DC at 3A with AC 500V dielectric withstand voltage, tested for 50,000 insertion/withdrawal cycles at 0.3 to 3.0 kgf, exceeding conventional consumer-grade barrel jacks.
Overview and Application Notes
The Reverse Sinking Mount (Mid-Mount) DC Power Jack Female Connector features an ultra-low profile height of 1.60mm combined with a chamfered/beveled mouth (斜口) mating interface. Specifically engineered for space-constrained, low-profile embedded systems, this high-reliability female DC receptacle delivers 24V 3A power transmission while maximizing board-edge space efficiency and mechanical drop-impact resistance.
Key Features
- Form Factor & Profile: Reverse mid-mount (sinking mount) installation with a 1.60mm overall profile height, lowering vertical footprint.
- Beveled Mating Interface: Engineered with a chamfered entry mouth (斜口) to guide plug insertion seamlessly and prevent terminal stubbing.
- Electrical Rating: Rated for 24V DC at 3A, delivering stable DC power distribution across industrial motherboards and edge devices.
- Contact Plating & Materials: Gold-plated copper alloy contact and shell construction for superior conductivity, low contact resistance, and anti-oxidation.
- Extended Mechanical Endurance: Tested for 50,000 mating cycles with a steady 0.3 to 3.0 kgf insertion/withdrawal force.
- Reflow-Ready Housing: Built from black thermoplastic PA10T (UL 94V-0 compliant) to withstand lead-free reflow soldering profiles and operate reliably from -55°C to +105°C.
- Environmental Compliance: Fully compliant with RoHS standards.
Engineering Specifications & PCB Integration
This female DC receptacle installs into a reverse mid-mount PCB edge cutout (6.90mm depth by 8.90mm width opening). The landing pattern incorporates four balanced anchor pads (2.10mm x 1.50mm) spaced 10.70mm laterally and spanning 8.55mm to 12.45mm longitudinally. All PCB layout dimensions require a tight tolerance of ±0.05mm to ensure optimal SMT solder joint formation, planarity, and strong resistance against mechanical wrenching forces during cable mating.
