4. FUNCTIONALITY
The TINJ‑101‑M12 acts as a mid‑span Power-over-Ethernet injector that combines separate Ethernet data and DC power input signals into a single PoE output for downstream devices. Its intelligent detection circuitry prevents accidental damage by sensing whether the connected device supports IEEE 802.3af or 802.3at standards before enabling power output. If no valid PoE signature is detected, the injector supplies data only and avoids energizing the connection.

Use Cases and Applications:
• Rolling stock communication systems (train infotainment, surveillance cameras, intercoms).
• Vehicle-mounted networking in buses, emergency vehicles, or industrial transport.
• Wayside industrial automation and trackside monitoring systems.
• IP surveillance cameras, IP telephony devices, wireless access points, and PoE sensors in rugged environments.
• Railway-certified networking where EN50155 compliance is mandatory.

Compatibility:
• Fully IEEE 802.3af/at compatible PD devices, including industrial IP cameras, access points, controllers, and VoIP devices.
• Compatible with M12 D-coded Ethernet infrastructure used in railway and vibration-prone systems.
