Power over Ethernet (PoE) injectors are networking devices that add electrical power to an Ethernet connection, allowing compatible equipment to receive both power and data through a single Ethernet cable. The injector connects to a power source and accepts a standard Ethernet data connection through a data-input port. Also referred to as power injectors, these devices are widely used with IP cameras, wireless access points, VoIP phones, and other networked equipment where a separate power connection may be inconvenient or unavailable.
RS Philippines stocks a range of PoE injectors, including single-port, multi-port, standard, and higher-power models to suit varying network installation requirements.
Types of PoE Injectors
PoE injectors are typically available in these configurations:
Single-Port PoE Injectors: A single-port PoE injector is designed to power one network device at a time, making it suitable for smaller installations or individual device upgrades.
Multi-Port PoE Injectors: These supply power to multiple Powered Devices from a single injector unit, subject to available power budget.
Standard PoE Injectors: Support devices operating under IEEE PoE standards such as IEEE 802.3af or IEEE 802.3at.
Higher-Power PoE Injectors: Support devices requiring higher power levels, including products compliant with IEEE 802.3bt PoE++. Examples include PTZ cameras, high-performance wireless access points, digital signage, and other higher-power network devices.
Gigabit PoE Injectors: Support Gigabit Ethernet or faster network speeds while simultaneously delivering power.
Industrial PoE Injectors: These may include rugged housings, DIN rail mounting, wider operating temperature ranges, and enhanced environmental protection.
Passive PoE Injectors: A passive PoE injector adapter supplies power without standards-based device negotiation and should only be used where voltage and pin compatibility are confirmed.
Industrial Applications of PoE Injectors
Power over Ethernet injectors provide both data and power through a single Ethernet cable, making them a practical solution for deploying network devices where local power outlets are unavailable.
IP Surveillance Cameras: Deliver power and network connectivity to PoE-enabled security cameras through a single cable.
Wireless Access Points: With a PoE injector, Wi-Fi access points can be installed in ceilings, corridors, and warehouses without a nearby electrical outlet.
VoIP Phones: Compatible desk phones draw power and data through the network cable without needing a separate adapter.
Access Control Systems: Readers, controllers, intercoms, and entry devices can be powered and networked through one cable.
Digital Signage and Displays: Networked screens and compatible control devices receive power through a PoE power injector where supported.
Industrial Networking: Sensors, controllers, gateways, and automation devices can be connected through a suitable PoE injector.
Small Network Upgrades: A single-port PoE injector suits deployments where one PoE device needs to join a non-PoE network.
