PROFINET Switches
Unmanaged Layer 2 priority switching tailored for Siemens S7-1200 / S7-1500 machine cells and remote ET200SP I/O polling.
EtherCAT Junctions
Convert vulnerable line daisy-chains into robust tree/star topologies for multi-axis CNC machining and robotic arms.
Industrial PoE+ Switches
Deterministic power sourcing equipment (PSE) built to keep extreme outdoor PTZ cameras and Wi-Fi 6 APs online safely.
The Valtoris Shared Hardware DNA
Regardless of which sub-series you specify, every switch shares these 4 non-negotiable physical laws.
-40°C to +75°C Fanless
Corrugated high-strength aluminum alloy casing acts as a passive heat sink, eliminating moving fan failures and preventing combustible dust ingress.
Dual Redundant Inputs
Equipped with dual power terminals backed by built-in reverse-polarity protection. If Power Source A fails, Source B takes over instantly.
Level 3 & 4 EMC Isolation
Heavy-duty optocouplers protect standard Ethernet data streams from massive ground loops and EMI/RFI noise blasted by cabinet VFDs.
35mm DIN-Rail Latch
Standardized industrial mounting brackets allow technicians to snap the unit onto control panel rails in seconds without specialized tooling.

Frequently Asked Questions
Why can’t I put a cheap commercial office switch inside a factory control panel?
Commercial switches fail in OT panels due to three physical vulnerabilities: 1) Electrolytic capacitors: Commercial power supplies dry up and rupture continuously when exposed to panel temperatures over +40°C. 2) Mechanical vibration: Standard RJ45 sockets lack internal spring dampening; machine vibration will cause micro-arcing and random packet disconnects. 3) Power dropouts: Commercial bricks rely on a single 110/220V AC wall plug; if that breaker trips, your entire PLC cell halts. Industrial switches solve all three via passively-cooled metal armor, dampening clips, and redundant DC9~60V inputs.
My IT department demands ‘Managed’ switches, but our OT panel uses ‘Unmanaged’. Which do I buy?
The engineering consensus is to implement a Split Core-Edge Architecture. Deploy unmanaged industrial Layer-2 switches at the raw machine edge (connecting your PLCs, remote I/O, and variable frequency drives). This keeps the local cell completely “plug-and-play” so maintenance technicians don’t have to configure IP tables during a 2:00 AM hardware swap. You then run a single uplink from that unmanaged edge switch back to IT’s managed core switch in the main control room.
Do standard non-PoE industrial switches require a 48V power supply?
No. Only our Industrial PoE+ switches explicitly require DC 48~57V to boost standard IEEE 802.3af/at power down the Ethernet wire. Our standard PROFINET and EtherCAT industrial switches accept a highly flexible wide voltage input of DC 9V to 60V (or AC 24V). You can wire them directly into your panel’s existing 12V or 24V DC auxiliary power bus.
What happens to standard OT devices if a 6kV lightning surge hits the switch’s network port?
Our switches are galvanic optocoupler isolation with level 3/4 ESD and Surge suppression chips. The transient surge will first strike the RJ45 PHY interface of the switch if a large outdoor lightning strike occurs to an exposed camera or Ethernet wire. The internal diode array instantly clamps the spike to ground via the DIN-rail grounding latch, safely absorbing the strike and sacrificing that individual port’s isolation transformer rather than allowing the thousands of volts to pass through and destroy your master PLC motherboard.
