FAQ

What is a PoE injector and why is it important for OEM applications?

A PoE injector is a device that delivers both power and data over a single Ethernet cable. It’s used when your Ethernet switch or network infrastructure doesn’t natively support Power over Ethernet. By injecting power into the cable, it allows you to power compatible devices like IP cameras, wireless access points, and IoT sensors—without requiring a separate power source.

For OEMs, PoE injectors offer several benefits. First, they simplify installation by eliminating the need for additional wiring or power adapters. This saves time, reduces cost, and makes deployments cleaner—especially in tight or remote locations.

Second, PoE injectors enable centralized power management. With the right setup, you can remotely monitor and control devices, reboot them if needed, and detect failures more easily.

Finally, they offer great flexibility. Whether your device needs 15W (PoE), 30W (PoE+), or up to 90W (PoE++), there’s an injector that fits—and manufacturers like Phihong even offer custom solutions for OEMs needing something more specialized.

PoE injectors are essential for enabling modern, connected devices—especially in applications where simplicity, space, and scalability matter.

What types of PoE injectors are available for industrial applications?

Industrial applications often require more robust, flexible, and powerful PoE solutions than standard commercial environments. PoE injectors for these scenarios are built to withstand harsh conditions and support mission-critical devices with higher power demands.

There are several types available:

• Single-Port and Multi-Port Injectors: Used depending on the number of devices being powered at a single point.
  
• DIN Rail Mount Injectors: Ideal for control panels and factory automation systems.
  
• Outdoor-Rated Injectors: IP67-rated units that resist water, dust, and temperature extremes—perfect for surveillance, transportation, and smart cities.
  
• High-Power (802.3bt) Injectors: Capable of delivering 60W to 90W or more, these are used for devices like pan-tilt-zoom (PTZ) cameras, displays, or industrial IoT hubs.
  

You’ll also find industrial injectors with features like surge protection, redundant power inputs, and wide temperature range operation.

When sourcing for industrial use, it’s important to look beyond wattage. Make sure the PoE injector’s form factor, compliance, and environmental specs match your system needs. A trusted manufacturer will help guide you to the right configuration and ensure reliable, long-term deployment.

How do I know which PoE standard (af, at, bt) I need?

The PoE standard you choose depends on how much power your end device requires—and how you plan to manage your infrastructure. Here’s a quick breakdown:

• IEEE 802.3af (PoE): Delivers up to 15.4W per port. Suitable for low-power devices like basic IP cameras, phones, or access control panels.
  
• IEEE 802.3at (PoE+): Delivers up to 30W per port. Used for more demanding devices like wireless access points, VoIP phones, or PTZ cameras.
  
• IEEE 802.3bt (PoE++): Supports 60W (Type 3) or up to 90W (Type 4). Ideal for high-power devices such as digital signage, industrial controllers, and multi-radio access points.
  

For OEMs, the decision comes down to your device’s power draw and environmental factors. If you’re designing a product from scratch, it’s smart to select the lowest viable standard to keep costs and heat generation down—unless you expect future features to require more.

A good manufacturer can help analyze your device’s power budget and recommend an injector that meets today’s needs with room to grow.

Can PoE injectors be customized for OEM use?

Yes—many manufacturers offer custom PoE injectors to better match the needs of OEMs with unique performance, design, or compliance requirements. Customization can range from adjusting the power output to designing the enclosure to fit within a specific product or cabinet.

Common customizations include:

• Output voltage or current range adjustments
  
• Unique form factors (slim, panel-mount, outdoor housing)
  
• Surge protection or EMI filtering for sensitive environments
  
• Different connector types or integrated cabling
  
• Compliance for specialized industries (medical, telecom, automotive)
  

Custom PoE injectors are especially helpful when you’re building a device that will be deployed in non-standard environments or when certification requirements go beyond the basics.

If your project demands something off the beaten path, it’s worth partnering with a manufacturer that can build exactly what you need—while supporting you through testing, certification, and scale.
