MK-S Series Power Relays


Omron and Digi-Key introduce relays with DC load switching models that can switch

Omron's MK-S Relays have a wider operating temperature and models with lockable test buttons. The new test button models also display a nameplate and are ready for order.

The MK-S relay is an incredibly small relay that can switch 220VDC 10A resistive load with large contact gap by the double break contacts and arc blow-out structure by the permanent magnet.
