Allen-Bradley 800T-H4A C01 Servo Drive

The Allen-Bradley 800T-H4A is a 30 mm diameter selector switch in the 800T family, engineered for durable panel mounting in industrial control applications. It functions as a handheld operator input to select between control paths or operating modes within a machine, typically wired into the control circuit to influence sequencing or mode selection. As a member of the 800T lineup, the H4A variant shares mounting and actuation interfaces with other 800T devices, enabling straightforward panel integration with compatible 30 mm pushbutton devices and operator assemblies. This model is commonly used in Allen-Bradley control panels and automation installations where a reliable, field-replaceable selector input is required.
