Frequently Asked Questions
What are the mechanical advantages of a 4.30mm mid-mount sinking RJ45 connector?
A mid-mount sinking RJ45 connector recesses 4.30mm into a pre-routed PCB edge cutout rather than sitting on top of the surface. This reduces above-board profile height to fit ultra-thin enclosures while utilizing through-hole DIP solder legs to absorb repeated mating force and mechanical vibration.
What is the recommended PCB cutout and footprint for this sinking modular jack?
The board requires an edge cutout of 14.20mm width with 0.70mm lateral relief notches and 6x R0.50 fillets. The pin layout uses 8x Ø0.90mm through-holes on a 1.02mm pitch (7.14mm span) with a 2.04mm grid offset, complemented by LED leads and dual Ø2.40mm shield retention slots holding a ±0.05mm layout tolerance.
What LED indicators are integrated into this port and what do they indicate?
The front mating face features integrated dual LEDs with Orange on the left side and Green on the right side. These LEDs deliver immediate visual diagnostics for link connectivity, speed status, and transmission activity without requiring external light pipes or panel-mounted LEDs.
How do the materials and plating ensure environmental and electrical reliability?
The component uses a nickel-plated stainless steel shell for full EMI/RFI shielding and corrosion prevention. The phosphor bronze contacts feature selective gold plating on the mating interface and tin on solder tails, maintaining contact resistance below 30 mΩ under 90%–95% RH and across -40°C to +85°C operating temperatures.
Overview and Application Notes
This mid-mount sinking RJ45 8P8C female modular jack features integrated dual LED indicators (Orange Left / Green Right) alongside a 4.30mm below-board sinking depth and DIP through-hole mounting. Engineered specifically for low-profile industrial networking equipment, it significantly reduces vertical board elevation while ensuring superior EMI/RFI shielding, visual link status diagnosis, and rugged mechanical anchoring on slim circuit boards.
Key Features
- Modular Interface: Standard 8 positions and 8 contacts (8P8C) female modular jack port.
- Low-Profile Sinking Design: 4.30mm mid-mount sinking profile minimizes above-board stack height for compact chassis integration.
- Integrated Dual LEDs: Pre-assembled Left Orange and Right Green LEDs provide immediate visual feedback on link status and Ethernet activity.
- Durable Material System: Flame-retardant thermoplastic housing (UL 94V-0 black), phosphor bronze contacts with selective Au/Sn plating, and a nickel-plated stainless steel outer shield.
- Robust Electrical Integrity: Rated at 125 VAC RMS / 1.5A, contact resistance ≤ 30 mΩ, insulation resistance ≥ 1000 MΩ, and dielectric strength of 1000V AC RMS.
- Wide Operating Temperature: Qualified for harsh operating environments from -40°C to +85°C under 90%–95% relative humidity.
Engineering Specifications & PCB Integration
Designed for mid-plane edge-mounting with a 14.20mm panel cutout, 0.70mm lateral clearance notches, and 6x R0.50 corner fillets. The footprint layout incorporates 8x Ø0.90mm through-holes on a 1.02mm pitch (7.14mm total span) with a 2.04mm grid offset for signal contacts, supported by integrated LED solder posts and dual Ø2.40mm shield retention slots holding a ±0.05mm positional tolerance. Solder tails extend 1.60mm to ensure complete through-hole solder barrel fill across 1.20mm to 1.60mm FR-4 boards.
