1. Product Name
Allen Bradley 440T-MDALJ10BHJH Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALJ10BHJH is a corrosion-resistant safety interlock SWITCH, designed for wheat agricultural and industrial environments. It secures access to hazardous zones during grain processing, storage, and machinery operation.
3. Product Description
The Allen Bradley 440T-MDALJ10BHJH is a high-reliability safety interlock SWITCH, part of Allen Bradley’s 440T series tailored to mitigate risks in corrosion-prone wheat farms and industrial sites. This Allen Bradley SWITCH acts as a mandatory safety barrier: it restricts entry to high-risk areas—such as wheat silos, grain cleaning machines, or chemical-exposed industrial enclosures—only when equipment is fully shut down, grain processing cycles end, or safety conditions (e.g., chemical neutralization) are met, preventing injuries from moving parts or corrosive substances.
Constructed with anti-corrosion alloy housing and acid-resistant coatings, the Allen Bradley SWITCH withstands grain dust, agricultural chemicals (e.g., wheat pesticides), and industrial chemical fumes—key challenges for long-term equipment durability. It operates stably in a temperature range of -35°C to 80°C, adapting to cold wheat storage silos and high-heat industrial workshops. The Allen Bradley SWITCH supports seamless integration with wheat farm devices (e.g., grain level sensors, pesticide spray controllers) and industrial PLCs via standard electrical terminals, eliminating the need for custom adapters and reducing installation time. Its mechanical interlock mechanism uses a fail-safe design: the lock remains engaged until connected equipment power is cut off, avoiding risks from accidental startups common in rural agricultural settings. A dual-color visual indicator (red for locked, green for unlocked) helps workers quickly confirm safety status, enhancing operational efficiency.
Compliant with EN ISO 14119 and ISO 23387 (grain handling safety standards), this Allen Bradley SWITCH meets Category 3 safety requirements (Performance Level d, PLd). It handles a maximum current of 8A at 250V AC, has a mechanical service life of 300,000 operations (suitable for high-frequency wheat harvest cycles), and features compact dimensions (9.2×6.9×2.8cm)—fitting space-constrained setups like silo access panels or cleaning machine guards.
