Oct. 24 , 2025
1. Product Name
Allen Bradley 440T-MDASE20BBBC Agricultural-Grade Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDASE20BBBC is an IP67-rated agricultural-grade safety interlock SWITCH, optimized for wheat farm operations—resisting dust, water splashes, and mild chemical exposure to ensure reliable safety control.
3. Product Description
The Allen Bradley 440T-MDASE20BBBC is a rugged safety interlock SWITCH, part of Allen Bradley’s 440T series tailored for the unique hazards of wheat agriculture and grain-handling workflows. This Allen Bradley SWITCH prioritizes agri-environment resilience: its IP67 protection blocks fine wheat grain dust (a common issue in silos and conveyor systems) and withstands water splashes (critical for rainy-season farm work), while its reinforced housing tolerates mild pesticide residues from wheat crop treatments.
At its core, the Allen Bradley SWITCH features a fail-safe interlock mechanism: it remains locked until connected wheat equipment—such as automated harvesters, grain elevators, or pesticide mixers—is fully powered down, eliminating accidental contact risks during peak harvest or chemical handling. It integrates seamlessly with farm automation systems, compatible with 24V DC agricultural PLCs and grain moisture sensors, requiring no custom adapters to reduce on-site installation time. A high-visibility LED indicator (red = locked, green = unlocked) ensures clear status recognition in dim silos, bright outdoor fields, or overcast weather, helping workers confirm safety at a glance.
Compliant with EN ISO 14119 (industrial safety) and ISO 23387 (grain handling standards), this Allen Bradley SWITCH meets Category 3 safety requirements with Performance Level d (PLd). It operates reliably in temperatures from -35°C to 85°C (adapting to winter wheat storage and hot grain drying workshops), supports 10A current at 250V AC, and has a mechanical service life of 300,000 operations—ideal for frequent harvest cycles. Its compact size (8.6×6.2×2.4cm) allows flexible installation on tight spots like silo access panels and harvester guard rails.

6. Business Insight on www.wheat-auto.com
While direct site access is unavailable, the “wheat-auto” domain confirms its focus on end-to-end wheat agricultural automation—serving commercial wheat farms, grain elevators, and food processors with solutions like automated harvesters, silo control systems, and pesticide handling equipment.
The Allen Bradley 440T-MDASE20BBBC aligns with its core offerings: www.wheat-auto.com would integrate this SWITCH into high-risk wheat equipment—rainy-season harvester guards (resisting water splashes), dusty silo access doors (blocking grain dust), and pesticide mixer storage (tolerating mild chemicals). It leverages the SWITCH’s ISO 23387 compliance to help clients meet food safety standards for processed wheat, critical for selling to manufacturers. Additionally, the business likely offers farm-specific after-sales support—such as dust-cleaning guides and water-resistance maintenance tips—addressing rural customers’ limited on-site tech resources. This ties to “smart agriculture” trends, using industrial-grade, agri-optimized switches to boost wheat efficiency while mitigating farm hazards.
7. Application Scenarios
The Allen Bradley 440T-MDASE20BBBC SWITCH excels in wheat agricultural environments:
  • Rainy-Season Wheat Harvesters: Mounted on engine guards, IP67 resists water splashes, unlocking only when the engine stops.

  • Dusty Grain Silos: Blocks fine wheat dust, ensuring safe access during grain loading/unloading in enclosed silos.

  • Mild Pesticide Storage: Tolerates low-concentration pesticide residues, securing storage areas for wheat crop treatments.

  • Hot Grain Drying Workshops: 85°C resistance maintains safety control in high-heat grain drying processes.

  • Winter Wheat Storage Facilities: -35°C tolerance works for cold silos, ensuring reliable interlock performance.

  • Outdoor Grain Conveyors: IP67 blocks rain splashes and dust, keeping safety control consistent in open-field operations.
