OMRON G6CK-1117P-US-5VDC

Updated: 2026-07-18

Overview

The G6CK-1117P-US-5VDC is a miniature PCB-mount relay manufactured by Omron, a leader in industrial automation components. Designed for space-constrained applications, it combines reliability with a compact footprint. Its 5V DC coil makes it compatible with microcontroller circuits and low-voltage control systems. This relay belongs to the G6CK series, known for their high dielectric strength and long mechanical/electrical lifespan. Typical applications include factory automation, test equipment, and telecommunications devices where precise low-power switching is required.

Structure and Working Principle

The relay consists of an electromagnetic coil, movable armature, and SPDT (Single Pole Double Throw) contacts. When 5V DC is applied to the coil, the generated magnetic field pulls the armature to change the contact state. The silver alloy contacts ensure low contact resistance and high durability. Internal arc suppression mechanisms minimize contact wear during switching. The transparent dust cover allows visual inspection without disassembly. The PCB pins are designed for wave soldering, with a standard 10mm pin spacing for compatibility with breadboards and industrial PCBs.

Key Features

1) Compact dimensions (20×10×15mm) save board space; 2) 5V DC coil with low power consumption (200mW nominal); 3) 10A resistive load capacity at 250V AC/30V DC; 4) High insulation resistance (1,000MΩ min); 5) Meets international safety standards including UL and CE. Additional features include shock resistance up to 100m/s² and vibration resistance to 10-55Hz. The relay's operating temperature range (-40°C to +70°C) ensures reliability in harsh environments. Gold-plated terminals prevent oxidation for consistent performance over time.

Application Areas

Primary applications include industrial control panels, HVAC systems, and power distribution units where galvanic isolation is needed. The relay's fast response time (10ms max) makes it suitable for timing-critical automation processes. In consumer electronics, it's used in smart home devices for safe switching of higher-voltage components. Medical equipment manufacturers value its reliability for patient monitoring systems. The moisture-resistant design also suits agricultural automation applications with high humidity exposure.

Maintenance and Precautions

For optimal performance, avoid switching inductive loads (like motors) without proper suppression circuits. Regularly inspect contacts for carbon buildup if used near maximum ratings. Never exceed the maximum switching frequency (1,800 operations/hour). When soldering, limit iron temperature to 350°C for ≤3 seconds to prevent housing damage. Store unused relays in anti-static packaging with desiccant to prevent contact oxidation. For high-altitude use above 2,000m, derate the load capacity by 3% per additional 300m due to reduced heat dissipation.

B2B Procurement Guide

Industrial buyers should specify the exact model (including trailing letters indicating batch codes). MOQs typically start at 100 pieces, with price breaks at 1,000+ units. Lead times average 4-6 weeks for custom configurations. Verify certifications needed for your industry (e.g., medical-grade may require additional documentation). Consider purchasing spare contact sets for high-cycle applications. Reputable distributors provide lifecycle forecasts—critical for long-term projects where obsolescence could disrupt production.
