Product Introduction

G2R-L14E-DC12 is a classic model of high-capacity PCB power relays from OMRON G2RL series. It features a 12V DC coil rated voltage and 1 Form C (SPDT, Single-Pole Double-Throw) contact configuration. Adopting a 4-pin through-hole package, this relay is specially designed for applications requiring compact size and high current switching capability.

As an upgraded product line of the standard G2R series, the G2RL series maintains a compact dimension of approximately 29mm × 12.7mm × 15.7mm, while raising the rated contact current to 16A and greatly reducing coil power consumption. The entire product line has obtained UL, CSA, VDE (TÜV) and CQC safety certifications and complies with RoHS directives. It is widely applied in home appliances, industrial control, building automation and power conversion equipment. For project development, users can obtain G2R-L14E-DC12 samples and check real-time inventory via SMCC, an authorized OMRON distributor, to ensure stable supply from R&D verification to mass production.

Application Scenarios

Home Appliances

HVAC Systems: G2R-L14E-DC12 controls compressor start/stop and four-way reversing valves of outdoor air conditioner units. Its 16A @ 250VAC rating covers 1HP to 3HP household inverter air conditioners. The 5,000VAC coil-to-contact withstand voltage protects controllers against lightning surges. It is also used for heating and cooling circuits of air purifiers and dehumidifiers.

Major Kitchen Appliances: In induction cookers, electric ovens and dishwashers, this relay switches main heating circuits, water pumps and fans. The -40°C ~ +85°C temperature range adapts to extreme working environments of kitchen equipment.

Washing Machines & Dryers: It controls motor forward/reverse rotation, heaters and drain pumps. The 200,000-cycle half-load electrical life ensures long-term reliable operation of laundry equipment.

Industrial Control

PLC Output Interfaces: G2R-L14E-DC12 is widely used for digital output modules of medium and small PLCs. The 12V DC coil can be driven directly by MCU GPIO with ULN2003 and other drivers. The 16A contact capacity can drive AC contactors, solenoid valves, indicators and alarms without extra amplifiers.

Control Cabinets & Power Distribution: It is applied for signal isolation, logic interlock and motor/pump control in industrial cabinets. High insulation provides sufficient safety margin for strong & weak current isolation, complying with IEC 60255 and IEC 61810 standards.

Building Automation

Smart Lighting Control: This relay switches lighting circuits in smart lighting modules. 16A current meets the load requirement of single circuits up to 3,680VA @ 230VAC. 20 million mechanical cycles support frequent switching for sensor-activated lighting systems.

Building Equipment Monitoring: It controls fan speed of FCU, motorized valves and exhaust fans. The compact size enables multi-circuit design on DIN rail modules and PCBs.

Selection Guidelines

Model Replacement Notice: G2R-L14E-DC12 has similar appearance with G2R-1A4-DC12 (SPST-NO), but different contact types. Please check schematics before replacement. G2R-1A4-DC12 can be used as an alternative if the circuit supports SPST-NO configuration during supply shortage.

PCB Layout Reference: 4-pin SIP package with 5.08mm pin pitch (0.2 inch), high compatibility. Alternative products like TE RT series and Panasonic JS series are available. Please verify coil power, withstand voltage and certifications before replacement.

Soldering Process: Compatible with wave soldering. Max soldering temperature: 260°C, duration ≤ 5 seconds. Not suitable for reflow soldering. Do not immerse the whole relay into cleaning solvent.

Inventory & Samples: G2R-L14E-DC12 is a standard mass-production product with stable global supply. Lead time is 4 to 8 weeks normally. SMCC provides stable inventory, professional selection support and alternative recommendations to accelerate product launch.
