Lite Managed PoE+ Switches

Lite Managed 4 x 10/100/1000 PoE+ & 2 x FX/GbE SFP Industrial Switch, Aluminum


SEN-8424PL is a Lite managed industrial switch with four 10/100/1000BASE-T and two SFP ports for harsh industrial environments. It is built with industrial-grade components, enclosed in IP30 aluminum casing, and designed to withstand vibration, shock, free fall, and temperatures ranging from -40°C to 75°C. It is equipped with a variety of management tools for configuration of a desired network. It also has dual power inputs to ensure maximal reliability and features such as auto-negotiation, rate limitation, and QoS (Quality of Service) to optimize network performance.


Robust Electrical and Electromagnetic Safeguard
Engineered to withstand EMI (electromagnetic interference), ESD (Electrostatic discharge), power surge, over voltage, over current, and reverse polarity.

Redundant Power System
Powered simultaneously with two different power sources, e.g. SDR-480P-48 power supply and IRA-120/IRA-160 DIN-rail mountable AC to DC power adapter, with power failure alarm.

Auto Negotiation of Link Speed
Auto-negotiation of data transmission speed between the switch and the connected PLC (Programmable Logic Controller).

Volktek continues to develop client-valued functions. Please call us for more details.


In designing the SEN-8424PL, the absolute necessary management functions were integrated to enable the configuration and monitoring of the switches. This allows the SEN-8424PL switches to bring added value to areas where unmanaged switches cannot deliver the required performance. It can also be used when fully-managed switches are not needed, due to the superfluous functionality or complex operation.
