ZERO-RS Switches – Industrial suitability at a new level.
Maximum reliability thanks to long-term availability, industrial-grade components and sophisticated protective measures.
Compact DIN rail mounting
Only 17.5mm wide – ideal for confined control cabinets. Snap mounting on DIN rail according to EN 60715.
ESD & surge protection
Suppressor diodes directly on the Ethernet ports provide effective protection against overvoltage and electrostatic discharge.
Pulse-resistant resistors
For termination and as protection against transient interference – ideal for the harshest environmental conditions.
High insulation strength
Separate ground concepts and reinforced insulation between ports and supply for maximum operational reliability.
Long-term availability
All components are industrial-grade and designed for long-term availability – ideal for series products.
Industrial-grade chipset
No Office Ethernet: All key components, including Ethernet PHYs, are for -40°C to +85°C specified.
Network technology for compact control cabinet solutions
ZERO-RS switches are ideal for space-saving installation in control cabinets and distribution boards – wherever reliability, temperature resistance, and compatibility with PROFINET are required. Whether in traditional factory automation, smart buildings, or modern robot cells: ZERO-RS switches bring Ethernet connectivity wherever it's needed.
