How Do PoE Injectors Work?
Consider a PoE injector as an intermediary between a non-PoE compatible network switch and an external entity like a PoE camera. At the junction point, power is introduced to the Ethernet cable, thus making it possible for any attached device compliant with the IEEE 802.3 PoE standards (af, at, or bt) to receive sufficient power.
PoE injectors offer DC power to devices classified as “low power” – the majority only necessitate 15 watts or less for functioning. Nevertheless, the PoE standards can cater to devices needing up to 30 or 60 watts. Frequently, PoE injectors are utilized to link and power devices in zones with restricted access to or absence of traditional power outlets.
Given their adaptability, a variety of PoE injectors find installation in manufacturing or industrial settings such as factories and expanse outdoor areas. This leads to them being equipped with fortified features to withstand severe conditions. In particular, industrial-class PoE Injectors:
– Come encased in a tough DIN rail mount housing.
– Can effectively perform under broad temperature variations.
– Possess shock and vibration resistance.
– Provide enhanced protection from electrical disturbances.
– Guard against current and voltage surges.
