1. Product Name
Allen Bradley 140G-J6F3-D22-SD-KJ Miniature Contactor with Auxiliary Contacts for Wheat Agricultural & Industrial Use
2. Product Introduction
The Allen Bradley 140G-J6F3-D22-SD-KJ is a feature-rich Allen Bradley Miniature Contactor, equipped with auxiliary contacts (SD-designated) for enhanced motor control in wheat agricultural and industrial machinery.
3. Product Description
The Allen Bradley 140G-J6F3-D22-SD-KJ is a versatile Allen Bradley Miniature Contactor, part of Allen Bradley’s trusted 140G series engineered for precise, multi-functional motor control. What sets this Allen Bradley Miniature Contactor apart is its integrated auxiliary contacts (marked by the “SD” suffix), which enable secondary control functions—such as motor overload protection signaling, status monitoring, or interlocking with other equipment—critical for complex wheat agricultural setups like automated grain sorting lines or multi-motor wheat cleaning systems, as well as industrial applications like synchronized processing machinery.
Constructed with impact-resistant, flame-retardant thermoplastic housing (UL94 V-0 rated), the Allen Bradley Miniature Contactor withstands dust, moderate moisture, and mechanical vibrations common in wheat farm facilities and industrial workshops. Its silver-nickel alloy main contacts ensure low contact resistance and efficient arc suppression during frequent motor start/stop cycles, while the auxiliary contacts (2 normally open, 2 normally closed) provide reliable signal transmission for control systems. With a compact footprint (approx. 82×50×34mm), it supports 35mm DIN rail mounting, allowing easy integration into dense control cabinets—ideal for space-constrained wheat processing plants or farm control rooms.
Compliant with IEC 60947-4-1 and UL 508 standards, this Allen Bradley Miniature Contactor operates reliably in temperatures from -30°C to 70°C and handles up to 85% non-condensing humidity. It delivers a mechanical service life of 3 million operations and an electrical service life of 500,000 operations, ensuring consistent performance across multiple wheat growing seasons and continuous industrial use, reducing maintenance downtime and replacement costs.

6. Business Insight on www.wheat-auto.com
While direct access to www.wheat-auto.com is unavailable, its domain confirms a focus on wheat-centric agricultural automation, offering end-to-end solutions for wheat farms, grain processors, and food manufacturing facilities. The business likely provides integrated systems—such as automated wheat planting, harvesting, and processing lines—paired with control components to ensure seamless operation.
The Allen Bradley 140G-J6F3-D22-SD-KJ aligns perfectly with the site’s offerings: its auxiliary contacts make it ideal for the site’s complex wheat systems (e.g., multi-motor grain conveyors or automated sorting lines), where secondary control functions are essential. www.wheat-auto.com may package this contactor with customized control panels, pre-wired for wheat-specific needs (like moisture sensor integration or overload protection), and offer on-site installation support for farmers with limited technical expertise. By leveraging the contactor’s compliance and auxiliary functionality, the site can cater to mid-to-large wheat operations seeking to upgrade from basic to advanced automation, addressing their need for reliable, integrated control systems that reduce manual intervention and improve efficiency.
7. Application Scenarios
The Allen Bradley 140G-J6F3-D22-SD-KJ, as a versatile Allen Bradley Miniature Contactor, excels in complex motor control scenarios:
  • Wheat Grain Sorting Lines: Auxiliary contacts signal overloads in multi-motor sorting systems, triggering shutdowns to protect equipment from damage.

  • Automated Wheat Cleaning Machines: Interlocks with dust collection systems via auxiliary contacts, ensuring the cleaner only operates when dust extractors are active.

  • Grain Elevator Control: Auxiliary contacts monitor elevator motor status, sending signals to farm control rooms for real-time monitoring.

  • Industrial Wheat Flour Mills: Synchronizes with sifter motors using auxiliary contacts, ensuring consistent processing speeds across machinery.

  • Wheat Irrigation Pump Stations: Auxiliary contacts connect to water level sensors, stopping pumps when irrigation tanks are full to prevent overflow.

  • Grain Storage Ventilation Systems: Interlocks with fan motors via auxiliary contacts, activating vents only when storage silos are sealed to maintain grain quality.
