Network Isolators
Galvanic isolation. Patient safety. Made in Germany.
Certified patient safety for medical applications.
10 Gbit/s with full galvanic isolation.
International approvals for worldwide use.
The isolator interrupts every electrically conductive connection, the signal lines and the shield.
Data transmission continues by electromagnetic induction, in exactly the frequency range Ethernet uses for it. The isolator needs no power supply of its own and no driver.
It prevents potential equalising currents and protects against overvoltages in the network cabling. Voltage withstand strength: 4.0 to 6.0 kV AC, and the 6.0 kV is reached by the EN-60KDS and the EN-76 series.
Network isolators sit in copper cables that carry data and must carry no current.
The form factor decides where the isolator sits.
Three routes to the right model, depending on how precisely you know your requirement. The assistant and the comparison cover network isolators only.

View in the shopA network isolator galvanically isolates an Ethernet connection without interrupting the transmission of network data. This reduces DC and AC voltages and unwanted equalising currents between connected devices. In medical technology above all, but also in test and measurement, industry, audio applications and networked computer systems, galvanically isolated Ethernet connections are an important technical solution.
The EMOSAFE network isolators by EMO Systems were developed specifically for the galvanic isolation of Ethernet interfaces. The product family covers different form factors and performance classes for external use, panel mounting and PCB assembly. Depending on the model, data transmission up to 10 Gigabit Ethernet (data rates up to 10 Gbit/s) is possible.
A network isolator is an electrical isolating device for Ethernet connections. It prevents a continuous galvanic connection between the connected network components while data transmission is maintained.
In an EMOSAFE network isolator, the Ethernet signals are transmitted through specially developed transformer modules by electromagnetic induction. No direct electrically conductive connection between the two sides of the isolator is required.
A key advantage: EMOSAFE network isolators need no power supply of their own, no drivers and no firmware. They are placed between the network and the end device and work passively.
An Ethernet connection consists of differentially transmitted signals. Galvanic isolation interrupts the electrically conductive connections between the two sides. The information is transmitted across a galvanic isolation barrier instead.
In simplified form, the principle looks like this:
Network → Ethernet cable → EMOSAFE network isolator → Ethernet cable → end device
The data is transmitted while the direct electrical connection between the two sides stays separated.
This reduces unwanted equalising currents between network components and connected devices.
In medical applications, the galvanic isolation of signal interfaces is particularly important. IEC 60601-1 defines requirements for the electrical safety of medical electrical equipment and systems. Network connections must be part of the assessment of protective measures.
EMOSAFE network isolators are used in applications where the Ethernet interfaces of medical devices must be galvanically isolated according to the respective requirements.
Depending on the application and the product variant, requirements for isolation voltage, form factor and protection concept can differ. A network isolator should therefore always be selected on the basis of the specific device, the interface and the applicable standards.
The EMOSAFE series offers a wide range of variants, including models for:
Depending on the model, the specially developed transformer modules achieve dielectric strengths of up to 6,000 V AC or 8,500 V DC. The three-layer insulation supports high demands on electrical isolation. At the same time, transmission losses are designed so that the usual Ethernet link lengths of up to 100 metres can be used in suitable network configurations.
A network isolator does not necessarily reduce network performance. EMO Systems offers various EMOSAFE models for fast Ethernet connections. The current range includes Gigabit models and variants for 10 Gigabit Ethernet.
Which variant is suitable depends on data rate, installation situation, interface and the isolation required, among other things.
EMO Systems develops and manufactures EMOSAFE network isolators in Germany. Its quality management is certified to DIN EN ISO 9001 and DIN EN ISO 13485. Every EMOSAFE network isolator is tested individually before delivery. Among other things, the dielectric strength is checked and documented. Relevant transmission parameters such as insertion loss, return loss and near-end crosstalk are tested as well.
Besides medical technology, network isolators are used in many other fields:
A network isolator galvanically isolates an Ethernet connection. Data transmission is maintained while the direct electrical connection between the connected systems is interrupted.
EMOSAFE network isolators transmit Ethernet signals through specially developed transformers by electromagnetic induction. No continuous galvanic connection between the two sides is required.
No. EMOSAFE network isolators work passively and need no external power supply.
EMOSAFE network isolators are designed for low-loss signal transmission. Depending on the model, they support Ethernet data rates up to 10 Gigabit Ethernet.
A medical network isolator is a galvanic isolating device for Ethernet interfaces in medical applications. It must be part of a protection concept for medical electrical equipment.
EMOSAFE network isolators are developed for medical applications according to the relevant requirements. Suitability must be assessed for the specific product variant and application.
