Key Features
- 8P8C (RJ45) right-angle configuration enabling PCB-edge panel-mount Ethernet port with 45-degree cable exit
- Integrated shield providing EMI noise rejection on 10/100/1000 Mbps Ethernet data lines
- Built-in status LEDs for link and activity indication without requiring separate LED components on the PCB
- Through-hole mounting with right-angle leads compatible with wave solder and selective solder PCB assembly
Applications
The RJHSE-5381A8 is used in industrial Ethernet switches, embedded networking boards, and IoT gateway devices where a panel-mountable RJ45 port with integrated shielding and LED status indicators is needed. Its right-angle 8P8C configuration positions the cable exit parallel to the PCB surface, making it ideal for chassis-mounted boards where connectors must align with rear panel cutouts at standard 45 mm height. The integrated shield reduces EMI emissions on 10/100 Mbps Ethernet links in EMC-sensitive industrial and telecommunications equipment.

Frequently Asked Questions
What connector type and pin count does the RJHSE-5381A8 use for Ethernet connectivity?
The RJHSE-5381A8 uses an 8P8C (8 positions, 8 contacts) RJ45 modular jack, which is the standard interface for 10BASE-T, 100BASE-TX, and 1000BASE-T Ethernet connections. All 8 pins are available for full Gigabit Ethernet wiring, and the right-angle orientation positions the socket opening perpendicular to the PCB plane so cables exit horizontally toward the chassis panel cutout.
How does the integrated shield on the RJHSE-5381A8 benefit Ethernet signal integrity in industrial environments?
The metallic shield on the RJHSE-5381A8 provides a continuous ground enclosure around the 8 signal contacts, attenuating EMI coupling from nearby switching power supplies, motor drives, and relay coils common in industrial environments. When connected to the PCB ground plane through the shield tabs, it reduces both radiated emissions from the Ethernet port and susceptibility to external noise on 10/100 Mbps data lines, helping the end product meet CISPR 32 and EN 55032 EMC limits.
What do the integrated LEDs on the RJHSE-5381A8 indicate and how do they simplify PCB design?
The integrated LEDs in the RJHSE-5381A8 provide link status and activity indication directly in the connector body, eliminating the need for separate LED components, current-limiting resistors, and routing traces to a remote indicator location on the PCB. Typically, one LED indicates a live link connection (lit when a partner device is detected) and the other blinks to show Ethernet packet activity, giving network technicians an immediate visual status check without test equipment at distances up to several meters.
Which PCB assembly processes are compatible with the RJHSE-5381A8 right-angle through-hole connector?
The RJHSE-5381A8 uses right-angle through-hole leads compatible with wave soldering and selective soldering processes standard in industrial electronics production. The right-angle mounting orientation keeps the connector body above the PCB surface, so selective solder nozzles can access the lead rows without interference from nearby SMD components. For prototype quantities, the through-hole pins also support manual hand-soldering with a standard iron, with typical solder joint forming at 300°C to 360°C iron tip temperature over 1 to 2 seconds per pin.
