Technical Details

This RJ45 jack features a single-row, 8-position/8-contact (8P8C) configuration compliant with Ethernet standards. The liquid crystal polymer (LCP) glass-filled housing provides excellent thermal stability and mechanical strength. Contacts are made from copper alloy with a 0.76μm gold flash finish, ensuring low insertion loss and corrosion resistance. The downward-facing tab and right-angle orientation minimize vertical space requirements, making it ideal for constrained designs.

Typical Applications

• Industrial Control Systems (PLCs, HMIs)
• Networking Equipment: Routers, Switches, Modems
• Telecommunications Infrastructure
• Embedded Computing & IoT Gateways
• Test and Measurement Devices

About RJ45 Jacks

RJ45 jacks form the physical interface for Ethernet networks, enabling wired data transmission between devices. Their standardized 8P8C configuration supports protocols like 10BASE-T and 100BASE-TX, making them foundational to LAN infrastructure. Proper jack selection impacts network stability, EMI resistance, and data throughput.

Right-angle jacks like the 0955012881 offer space-efficient PCB integration in chassis-mounted equipment. Through-hole solder termination provides superior mechanical retention versus surface-mount alternatives, while unshielded designs reduce cost in controlled EMI environments.

Packaging

Supplied in protective industry-standard trays to prevent damage during shipping and handling. Custom packaging options available upon request.

FAQs

Q: Is this jack compatible with Cat5/Cat6 cables?
A: Yes, it mates with standard RJ45 plugs but is rated for Cat3 speeds (10 Mbps). For higher bandwidth, consider shielded Cat5e+ jacks.

Q: Does it support Power over Ethernet (PoE)?
A: While compatible with PoE connections, verify voltage/current requirements in your application as this is an unshielded jack.

Q: What’s the benefit of the board lock feature?
A: It prevents connector dislodgement during cable insertion/removal, critical in high-vibration environments.

Q: Can I use this in outdoor applications?
A: The operating temperature (-40°C to 85°C) allows industrial use, but environmental sealing isn’t included. Add protective enclosures for moisture exposure.

Q: Are datasheets available?
A: Yes! Access the full Molex 0955012881 datasheet on PCXCo.com.

Q: How does gold flash plating enhance performance?
A: It reduces contact resistance and prevents oxidation, ensuring stable connections over thousands of mating cycles.
