Omron MK3P-I Industrial Relay With Socket Base

The Omron MK3P-I Industrial Relay with Socket Base is a 3PDT general‑purpose power relay for industrial control, featuring a 220 VAC coil and an 11‑pin PF113A plug‑in socket base for quick installation and replacement. It uses three Form C contacts (3PDT) and is rated for 10 A at 250 VAC resistive, 7 A at 250 VAC general, and 10 A at 28 VDC, with a maximum switching voltage of 250 VAC / 250 VDC and a maximum switching current of 10 A. Silver alloy contacts provide reliable conduction, while mechanical life is specified at least 5,000,000 operations and electrical life at least 100,000 operations. Operate time is up to 20 ms and release time up to 20 ms with an operating temperature range of -10°C to +40°C. Commonly used in control panels, machine control, motor control circuits, conveyors, packaging equipment, HVAC, and process automation lines to switch motors, solenoids, contactors, and signaling devices; typically paired with PF113A sockets for plug‑in field replacement. Common replacements include Omron MK3P-I, MK3PN-I, and MKS3P-I.
