Relays from Magnecraft & Struthers-Dunn come in a variety of shapes, sizes, and ratings including socket or DIN-rail mountable versions. Capacitive loads want to remain at constant voltage. When the contacts are closed, a current surge can weld the contacts together. Inductive loads want to keep a constant current. When relay contacts open, the voltage surges to keep the current constant. This surge causes arcing across the contacts. Programmable logic controllers (PLCs) and computer-based controllers are great for handling logic and data-collection tasks for industrial controls. But when it comes to

Dataline and DC Signal Surge Suppressors

Dataline and DC signal surge suppressors protect equipment from transient overvoltages present on data or DC signal lines.

Thyristor Surge Suppressors

Thyristor surge suppressors are semiconductor chips used to protect circuits and devices from over-voltage and over-current.

Safety Relays

Safety relays and control modules differ from conventional relays in that they have force-guided or positive-driven contacts.

Reed Relays

Reed relays are electrically-operated switching devices that consist of two thin, magnetic strips (reeds) encapsulated in a glass envelope. They are used to switch industrial components such as solenoids, contactors and starter motors.
