Allen-Bradley 800MR-PT16CK Push To Test Pilot Light

Allen-Bradley 800MR-PT16CK Push-To-Test Pilot Light is a 22.5 mm round indicator for 800MR control-station assemblies, offering a clear lens (CK variant) for easy visibility in panel enclosures. It houses an incandescent lamp and is specified for 110–120 V AC operation with a Transformer Type PTT arrangement, enabling a dedicated push-to-test action to verify illumination without energizing the control circuit. The unit features large-screw terminations and ships without a contact cartridge, aligning with the 800MR family’s mounting and wiring conventions for field-installable pilot-light modules. In typical panel applications, this pilot light serves as a status indicator for machines or control circuits, delivering a compact form factor that fits standard 22.5 mm round openings. The 800MR series integrates with Allen-Bradley’s legacy control-station hardware, providing a consistent indication option alongside other pushbutton and indicator assemblies used in industrial automation. This CK variant complements other 22.5 mm 800MR components by delivering reliable, simple-status signaling in environments where visibility and quick testing are essential.
