Allen Bradley 440T-AKEYE103DAA Trapped Key Safety SWITCH

Enhanced Safety Rating: PLe/ Category 4 certification provides maximum protection for high-risk industrial operations.

Extreme Temp Tolerance: -40°C to 70°C operating range suits foundries, refineries, and cold-storage facilities.

Impact-Resistant Build: Reinforced alloy housing withstands mechanical collisions, reducing damage risks.

Fail-Safe Mechanism: Key remains trapped until safety conditions are met, preventing human error-related accidents.

Cost-Effective Operation: 250,000-cycle lifespan and low maintenance needs cut long-term replacement costs.

Flexible Integration: Universal electrical interfaces work with most industrial control systems, simplifying setup.

Wheat Milling Plants: Installed on grain crusher guards—prevents access until the machine stops, even in dusty, high-temperature milling halls.

Metal Foundries: Used on furnace access doors, withstanding extreme heat while ensuring workers only enter after cooling and pressure release.

Cold-Storage Grain Facilities: Integrated into refrigerated warehouse doors, functioning reliably in sub-zero temperatures to control access to stored wheat.

Chemical Refineries: Mounted on reactor control panels, trapping keys until chemical processes conclude and vessels are depressurized.

Automotive Paint Shops: Applied to spray booth safety gates, resisting solvent fumes and high temperatures while ensuring safe entry for maintenance.

Mining Operations: Used on conveyor belt emergency stops in underground mines, withstanding dust and humidity to protect workers from moving parts.
