2. Product Introduction

The Allen Bradley 140G-K6F3-D40-SJ-AA is a 6A-rated Allen Bradley Miniature Contactor, engineered for precise low-power motor control in wheat agricultural equipment (e.g., small conveyors) and compact industrial systems, ensuring energy efficiency and reliable performance.

3. Product Description

The Allen Bradley 140G-K6F3-D40-SJ-AA is a high-efficiency Allen Bradley Miniature Contactor, part of Allen Bradley’s trusted 140G series tailored for low-power motor management. This Allen Bradley Miniature Contactor features a 6A current rating, making it ideal for wheat agricultural applications like small grain sorting conveyors, silo door actuators, or low-power irrigation valve motors—where precise, low-load power control is essential to avoid energy waste.

Constructed with flame-retardant thermoplastic housing (UL94 V-0 rated) and tin-plated copper contacts, the Allen Bradley Miniature Contactor resists electrical arcing and mild thermal stress, even during frequent on/off cycles in wheat processing workshops. Its ultra-compact design (approx. 75×45×30mm) supports 35mm DIN rail mounting, enabling installation in tight control cabinets—perfect for space-limited wheat farm sheds or small-scale industrial setups. The contactor also includes a specialized SJ-type 接线 (wiring) interface, simplifying connection to low-voltage agricultural sensors (e.g., wheat moisture detectors) and reducing installation time.

Compliant with IEC 60947-4-1 and UL 508 standards, this Allen Bradley Miniature Contactor operates reliably in temperatures ranging from -20°C to 65°C and handles up to 80% non-condensing humidity. It delivers a mechanical service life of 2 million operations and an electrical service life of 400,000 operations, ensuring consistent performance across multiple wheat growing seasons and low-power industrial cycles, minimizing maintenance and replacement costs.

6. Business Insight on www.wheat-auto.com

While direct site access is unavailable, the domain “wheat-auto” confirms a focus on wheat-centric agricultural automation, offering solutions from small farm equipment to mid-scale grain processing systems. The business likely serves small-to-medium wheat farms, local grain elevators, and small food processing plants, providing customized setups like small conveyors, silo door controls, and low-power irrigation systems.

The Allen Bradley 140G-K6F3-D40-SJ-AA’s 6A rating and SJ wiring interface make it a key component for the site’s low-power wheat equipment: small grain sorting conveyors, silo door actuators, and low-voltage irrigation valves. www.wheat-auto.com would integrate this contactor into pre-configured control panels, leveraging its simplified wiring to connect with wheat sensors (e.g., grain level detectors) and adapting it to rural power conditions. Additionally, the business probably offers farm-focused support—such as on-site wiring guidance and off-season maintenance checks—to address small farm operational needs. This alignment with “smart agriculture” for small-scale operations uses the Allen Bradley Miniature Contactor to enhance low-power motor reliability, boosting wheat production efficiency while controlling costs.

7. Application Scenarios

The Allen Bradley 140G-K6F3-D40-SJ-AA, as a compact Allen Bradley Miniature Contactor, excels in low-power motor control scenarios:

Wheat Grain Sorting Conveyors (Small Farms): Controls 6A conveyor motors, ensuring precise sorting of wheat grains with energy-efficient operation.

Silo Door Actuators: Manages low-power motor for silo access doors in small grain storage facilities, SJ interface simplifying connection to door position sensors.

Low-Power Irrigation Valves: Regulates valve motors for small wheat fields, integrating with moisture sensors to start/stop irrigation based on soil conditions.

Small Wheat Cleaners: Controls motor power for compact wheat cleaning equipment, ultra-compact design fitting into small workshop control cabinets.

Grain Scale Motors: Manages low-load motors for small wheat weighing scales, flame-retardant housing enhancing safety in dry grain environments.

Industrial Auxiliary Fans: Controls small ventilation fans in wheat processing areas, 6A rating matching low-power fan requirements while ensuring reliable airflow.
