1. Product Name

Allen Bradley 140MP-A3E-B16 24V DC Miniature Contactor

2. Product Introduction

The Allen Bradley 140MP-A3E-B16 is a high-reliability Allen Bradley Miniature Contactor, designed for 24V DC motor control in wheat agricultural and industrial systems, with robust build for harsh operational conditions.

3. Product Description

The Allen Bradley 140MP-A3E-B16 is a precision-engineered Allen Bradley Miniature Contactor, part of Allen Bradley’s 140MP series optimized for low-voltage motor management in critical applications. This Allen Bradley Miniature Contactor is specifically tailored to wheat agricultural operations—such as controlling grain elevator motors, wheat irrigation pump systems, and automated sorting machine drives—where 24V DC power is common (e.g., battery-powered mobile equipment) and resistance to dust, vibration, and temperature fluctuations is essential.

Constructed with impact-resistant thermoplastic housing (UL94 V-0 flame rating) and gold-plated auxiliary contacts, the Allen Bradley Miniature Contactor ensures stable performance in dusty grain processing facilities and vibrating mobile machinery. Its main contacts, made of silver-cadmium oxide alloy, minimize electrical arcing and wear during frequent on/off cycles—critical for equipment like intermittent wheat conveyor motors. The 140MP-A3E-B16 features a 24V DC coil (indicated by the “B16” designation) and a compact footprint (approximately 68×42×26mm), enabling seamless integration into tight control panels of battery-powered wheat harvesters or small-scale processing units. It also includes built-in overvoltage protection to shield against electrical surges, a key requirement for DC-powered agricultural equipment.

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 4 million operations and an electrical service life of 800,000 operations, ensuring long-term durability across multiple wheat growing seasons, while reducing maintenance downtime for farmers and industrial operators.

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, serving small-to-mid-sized wheat farms, mobile agricultural service providers, and compact grain processing facilities. The business likely offers tailored solutions: battery-powered mobile wheat equipment (e.g., portable harvesters, on-field sorters) and DC-powered grain handling systems—all requiring 24V DC-compatible control components.

The Allen Bradley 140MP-A3E-B16 aligns perfectly with this focus: its 24V DC coil matches battery-powered wheat machinery, and compact design fits mobile equipment’s limited control space. www.wheat-auto.com would position this Allen Bradley Miniature Contactor as a core component, emphasizing benefits like vibration resistance (for field use) and overvoltage protection (for battery systems). Additionally, the business may provide farm-specific support—such as DC wiring guides and battery compatibility checks—to address the needs of non-technical wheat producers. This alignment with “portable smart agriculture” trends helps smaller operations boost efficiency without relying on fixed AC power infrastructure.

7. Application Scenarios

The Allen Bradley 140MP-A3E-B16, as a specialized Allen Bradley Miniature Contactor, excels in 24V DC wheat agricultural and industrial settings:
