The OMRON MK2P-S is a heavy-duty, general-purpose plug-in power relay built for high reliability in industrial automation and control panel applications. The "S" suffix specifically denotes the inclusion of a built-in mechanical operation indicator and a lockable test button, allowing technicians to manually verify circuit operations.

Electrical & Performance Characteristics
  • Contact Ratings (Resistive Load): 10 A at 250 VAC / 10 A at 30 VDC (Note: While max switching voltage extends up to 250 VDC, maximum current capacity scales down at higher DC voltages to prevent arcing). 
  • Contact Ratings (Inductive Load): 7 A at 250 VAC. 
  • Contact Resistance: 50 mΩ max (initial). 
  • Dielectric Strength: 2,500 VAC (50/60 Hz for 1 minute) between the coil and contacts; 1,000 VAC between contacts of the same pole. 
  • Insulation Resistance: 100 MΩ minimum (at 500 VDC). 
  • Operating Time:
    • AC Coils: 20 ms maximum
    • DC Coils: 30 ms maximum 
  • Release Time: 20 ms maximum.
  • Endurance (Service Life):
    • Mechanical: 10,000,000 operations minimum (at 18,000 ops/hour)
    • Electrical: 100,000 operations minimum under rated load (at 1,800 ops/hour) [1]
Coil Options & Environmental Specs
  • Coil Power Consumption: Approximately 2.3 to 2.7 VA for AC models; approximately 1.4 to 1.5 W for DC models.
  • Ambient Operating Temperature: -10°C to +40°C (standard series) up to -40°C to +60°C depending on specific production generation/MKS variants.
  • Ambient Humidity: 35% to 85% RH.
  • Weight: Approximately 85 g to 90 g.
  • Standard Compliances: UL508, CSA C22.2, VDE, CENELEC, CE, and TÜV.
Wiring & Terminal Configuration (8-Pin Octal)
The relay is paired with a matching track-mounted socket (such as the Omron PF083A-E): 
  • Terminals 2 & 7: Coil power supply.
  • Terminals 1 & 8: Common (COM) contacts.
  • Terminals 3 & 6: Normally Open (NO) contacts.
  • Terminals 4 & 5: Normally Closed (NC) contacts
