Single Pair Ethernet Switches - From the Sensor to the Cloud.
Single Pair Ethernet is a crucial building block for fully transparent IP-based data communication from the sensor to the cloud. Control cabinet-free networking directly in the field with just one pair of wires.
Cross-Technology-Switches
T1|TX data hybrid ports enable the networking of all Ethernet participants, regardless of the transmission standard used.
Single Pair Ethernet Gigabit Type B
Gigabit speed with over 40 m of cable length. Shielded cables allow for significantly longer lengths and connection points.
Master|Slave Auto-Detection
Allows end devices to connect regardless of their configuration; the TERZ switch adapts to the master|slave auto-detection ports according to their role as master or slave.
Industrial Robustness
IP65/67/69K all-metal housing, resistant to salt spray and other aggressive environmental conditions.
Inductive Transformers
Galvanic isolation and excellent common-mode rejection, which is invaluable in environments with high electromagnetic interference.
Approval and Certification
Railway technology, agricultural vehicles, construction machinery, commercial vehicles, military, intralogistics
Robust network technology for mobile machines and special vehicles
Our SPE switches enable reliable, space-saving, and future-proof data communication in mobile machines and vehicles – even under extreme environmental conditions. Whether agricultural engineering, construction, logistics, public transport, or automated fleets: Our technology creates the basis for smart sensors, real-time control, and networked machines in modern vehicle architectures.
