Power Relays
MK-S(X)
MK-S-series Relays with DC-switching
Models That Can Switch 220 VDC, 10 A
(Resistive Load).
• Switch a DC load of 220 VDC, 10 A (resistive load).
• Models for AC Loads can switch 250 VAC, 15 A (resistive load).
• Lineup includes models with SPST-NO and SPST-NO/SPST-
NC contact forms.
• Using a SPST-NO/SPST-NC contact form enables detecting
contact welding. (When the NO contacts become welded, the
NC contacts will maintain a minimum distance of 0.5 mm.)
• Models available with operation indicators and built-in test
buttons.
• RoHS compliant.
• Standards: UL, IEC (TÜV certification)
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.

Note:
The values given above are initial values.
*1.
The contact resistance was measured for 1 A at 5 VDC using the voltage drop method.
*2.
The operate time was measured with the rated voltage imposed and any contact bounce ignored at an ambient temperature of 23°C.
*3.
The insulation resistance was measured with a 500-VDC insulation resistance tester at the same places as those used for checking the
dielectric strength.
*4.
The electrical endurance was measured at an ambient temperature of 23°C.
