Overview of Allen Bradley 440K-T11090
The Allen Bradley 440K-T11090 is a Trojan 5 series safety interlock switch designed for industrial applications requiring secure access control. Featuring a keyed lock style with a standard actuator included, this switch offers reliable performance with 2 normally closed (NC) and 1 normally open (NO) safety contacts. Its compact and durable construction uses glass-filled PBT housing, providing resistance against harsh environments. Rated IP67, it is fully sealed against dust and temporary water immersion, suitable for rigorous industrial conditions. The switch operates within a temperature range of -20°C to +80°C, ensuring stable function in various settings. With a break-before-make (BBM) contact action, the 440K-T11090 enhances safety by preventing simultaneous closing of contacts. Its design includes an M20 conduit connection for easy wiring integration and multiple head directions for flexible mounting[1][3][5].Key Features of Allen Bradley 440K-T11090
