Applications
This robust plug-in relay is suitable for harsh-environment applications demanding exceptional reliability and long service life. It delivers proven dependable performance when switching high DC inductive loads and low-current circuits. Boasting a compact form factor, a wide range of optional configurations and diverse socket options, the D-U200 series relays serve as an easy-to-use, highly flexible solution.
Description
This relay series is engineered for demanding rolling stock applications such as vehicle door control. Thanks to optimized structural design and carefully selected materials, the D-U200 relays withstand corrosive atmospheres, extreme low and high temperatures, shock, vibration, and environments ranging from dry to highly humid. An integrated snap-lock eliminates the need for external retaining clips, firmly securing the relay to its socket under all operating and mounting conditions.
All units come standard with a magnetic blow-out arc quenching system for high breaking capacity and extended contact service life, as well as back EMF suppression diodes.
