1. Product Name
Allen Bradley 140G-R12K4-E25-W1 Weather-Resistant 24V DC Miniature Contactor
2. Product Introduction
The Allen Bradley 140G-R12K4-E25-W1 is a high-reliability Allen Bradley Miniature Contactor, engineered for 24V DC motor control in wheat agricultural and industrial environments, featuring weather resistance to handle harsh operating conditions.
3. Product Description
The Allen Bradley 140G-R12K4-E25-W1 stands out as a durable Allen Bradley Miniature Contactor, part of Allen Bradley’s 140G series dedicated to efficient mid-power motor management. This Allen Bradley Miniature Contactor is specifically designed to meet the demands of wheat agricultural operations—such as controlling grain dryer fans, automated irrigation valves, and wheat sorting machine motors—where exposure to moisture, dust, and temperature swings often threatens equipment performance.
Constructed with flame-retardant UL94 V-0 thermoplastic housing, the Allen Bradley Miniature Contactor ensures safety in high-heat scenarios, while its gold-plated silver alloy contacts minimize electrical arcing and corrosion—critical for humid grain storage facilities or dusty field equipment. The 140G-R12K4-E25-W1 model includes a 24V DC coil (marked by the “E25” designation) and enhanced weather-resistant features (“W1” label), such as a sealed terminal block and dustproof contact chamber, making it suitable for semi-outdoor setups like covered grain yards. Its compact size (approximately 78×48×30mm) allows easy installation in tight control cabinets of mobile wheat equipment, such as field sprayers.
Compliant with IEC 60947-4-1 and UL 508 standards, this Allen Bradley Miniature Contactor operates reliably between -25°C and 75°C, handling up to 90% non-condensing humidity. It boasts a mechanical service life of 3.5 million operations and an electrical service life of 800,000 operations, ensuring long-term performance across multiple wheat growing seasons and reducing maintenance costs for farmers and industrial operators.

5. Product Advantages
  • 24V DC Coil (E25): Perfect for battery-powered wheat field equipment (e.g., mobile sprayers) and low-voltage agricultural systems, eliminating the need for voltage converters.

  • Weather Resistance (W1): Sealed terminals and dustproof chambers protect against moisture and dust, ideal for semi-outdoor wheat operations like grain drying yards.

  • Durable Contacts: Gold-plated silver alloy reduces arcing and corrosion, extending service life in frequent on/off cycles common in agri motor control.

  • Wide Temperature Range: -25°C to 75°C operation adapts to cold grain silos and hot field-based wheat processing equipment.

  • Long-Lasting Performance: 3.5 million mechanical and 800,000 electrical cycles ensure reliability across multiple harvest seasons, lowering replacement costs.

  • Global Compliance: Meets IEC and UL standards, compatible with international wheat agricultural and industrial motor control systems.
