937Z Zener Barriers

Our Bulletin 937Z Zener Barriers provide protection for electrical signals within hazardous areas. These barriers feature a narrow profile of just 12.5 mm to maximize control panel space. They also prevent the transfer of unacceptably high energy from the safe area into the hazardous area. Our Zener Barriers include positive polarity, which means the anodes of the Zener diodes are grounded. Depending on the application, increased or decreased intrinsic safety parameters apply for serial or parallel connection.
