Allen-Bradley 800T-E11B Pushbutton Cylinder Lock

The Allen-Bradley 800T-E11B Pushbutton Cylinder Lock is a 30 mm cylinder-lock insert designed for use with the 800T family of pushbutton operators, offering keyed control to secure a pushbutton in its selected position and prevent unauthorized operation. This variant provides a 2 normally open (NO) and 2 normally closed (NC) contact block configuration, compatible with the standard 800T-XA contact block. Such a setup supports multiple control paths in a single unit, enabling both signaling and interlock functions within industrial control panels. The 800T-E11B is intended for use with 30 mm pushbutton heads in the Allen-Bradley 800T line, making it suitable for machine control applications that require reliable lockout and reset capabilities during maintenance or safety procedures. In practice, it is commonly employed in lockout/interlock schemes, maintenance-mode protections, and start/stop interlocks where a keyed cylinder prevents cycling of the pushbutton when the system must remain safely isolated. For proper pairing, verify that the operator function and contact-block arrangement align with your 800T assembly, and use the standard 800T-XA block to realize the intended NO/NC logic. This configuration provides a durable, field-serviceable solution within standard industrial control cabinets, helping engineers meet safety and control requirements without compromising accessibility or reliability.
