MTL7707+ MTL7700 Series DIN-rail mounting safety barriers.
The ranges have evolved over the years but the latest MTL7700 range is unique in providing a broad range of benefits that the instrumentation engineer looks for in a modern barrier.
With the MTL7700, continuing the heritage, their commitment to zener barriers is confirmed for many years to come.
