MKS-X Series
General Purpose Relays

The Omron Electronics MKS-X Series General Purpose Relays are available in models for DC Loads (can switch 220 VDC, 10A resistive) and AC Loads (can switch 250 VAC, 15A resistive). The MKS-X series is the shortest general purpose relay in the world that can switch 10A @ 220VDC resistive load - at least 4mm shorter than all competitors. Omron Electronics MKS-X General Purpose Relays are ideally suited for switching valves, solenoids, contactor coils, and for power plant applications.

Note: If the L/R of an inductive load exceeds 7 ms with a Model for a DC Load, the arc interruption time must be less than
approximately 50 ms to use the Relay. Design the circuit so that the arc interruption time is 50 ms or less. These values
apply to a switching frequency of 30 times per minute.
