Omron MK3P-I Relay

The Omron MK3P-I relay is a three-pole, 3 Form C general-purpose power relay for industrial automation, offering reliable electromechanical switching with a 12 VAC coil and an 11-pin plug-in design typically paired with a PF113A socket base. It handles up to 10 A at 250 VAC resistive (7 A general use), and 10 A at 5 VDC, with a maximum switching voltage of 250 VAC / 250 VDC and a maximum switching current of 10 A. The contact material is silver alloy, and the device provides a mechanical life of 10,000,000 operations minimum and an electrical life of 100,000 operations minimum. Operate time and release time are each up to 20 ms for AC coil operation. Operating temperature range is -10°C to +40°C. Commonly used in control panels, machine control, motor control circuits, conveyor systems, packaging equipment, HVAC, and process automation lines to switch motors, solenoids, contactors, and signaling devices; the plug-in design enables quick installation and maintenance. Common replacements include Omron MK3P-I AC24, MK3PN-I AC24, and MKS3P-5 24VAC.
