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).
• 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 are also available with a built-in test button.
• Models for AC Loads can switch 250 VAC, 15 A (resistive
load).
• RoHS compliant.

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.
