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/SPSTNC 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.

The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/−20% for AC rated current and ±15% for DC coil resistance. 2. Performance characteristic data are measured at a coil temperature of 23°C. 3. The maximum allowable voltage is the maximum value of the allowable voltage range for the operating power supply for the relay coil. There is no continuous allowance. 4. The...

The P7M-06P, P7MF-06, and P7MF-06-D can be used with models for DC loads with an SPST-NO or SPST-NO/SPST-NC contact form or with models for AC loads with an SPST-NO or SPST-NO/SPST-NC contact form. 2. The P7MF-06-D has a built-in diode and can thus be used only with Relays with DC operating coils. Do not use it with a Relay with an AC operating coil. 3.

Safety Precautions Refer also to Precautions for All Relays. Precautions for Correct Use Installation Test Button • Models for DC loads (i.e., models with “X” in the model number) have permanent magnets built into the insulating block. If a permanent magnet or other magnetic body comes near the Relay, magnetic interference will occur with the built-in permanent magnet and the contact switching capacity will be decreased. • Models for AC loads do not contain a permanent magnet. • When mounting a P7MF-06(-D) Front-mounting Socket to a DIN Track, attach PFP-M End Plates on both sides of the Socket...
