We are pleased to announce that additional Zener barriers from STAHL have been added to isolate various control signal types from hazardous environments.

For automated systems installed in potentially explosive atmospheres (ex., oil and gas production), extra precautions must be taken to ensure the electrical circuits do not become ignition sources. Properly grounded Zener barriers isolate the electrical signal from the hazardous area. New barriers are available to protect the following circuits: 4-20 mA/PNP sensor, NPN sensor/dry contacts, pulse trains (11 or 18 VDC), and strain gauges.

STAHL Zener barriers come with a 1-year warranty.

Please check out our STAHL Intrinsically Safe Zener Barriers product offering for more details.
