We are committed to delivering safety and reliability in hazardous environments. The Zener Safety Barrier is meticulously designed to ensure the safe operation of intrinsically safe equipment in explosive atmospheres. By limiting the energy transferred to hazardous areas, these barriers prevent potential ignition sources, safeguarding both personnel and equipment.​

The DZB Zener Safety Barrier series boasts over 70 variations, including 1, 2, and 3-channel options, catering to a wide array of intrinsically safe applications. Certified with ATEX and IECEx Ex ia approvals, these barriers are suitable for use in various regions worldwide. Their standard 35mm DIN rail mounting ensures easy integration into existing systems, and they are fully compatible with a range of Deeter Electronics sensors. ​

Whether you’re operating in the oil and gas sector, chemical processing, or any industry requiring stringent safety measures, our Zener Safety Barriers provide the protection you need. Explore our range to find the perfect solution for your hazardous area applications.

Why are Zener barriers used with hazardous area sensors?
Zener barriers are often used with hazardous area sensors to help maintain intrinsic safety. They restrict electrical energy in the circuit so connected sensors and switches can operate safely in areas where explosive atmospheres may be present.
Are Zener barriers used with ATEX certified sensors?
Yes, Zener barriers can be used as part of an ATEX compliant system where intrinsically safe equipment is required. The full installation must be assessed to ensure the sensor, barrier, wiring and associated equipment are suitable for the hazardous area.
What does intrinsic safety mean in hazardous areas?
Intrinsic safety is a protection method that limits electrical and thermal energy so equipment cannot ignite an explosive atmosphere during normal operation or certain fault conditions. Zener barriers are commonly used to help achieve this in hazardous area circuits.
