Allen-Bradley PHD RLS1 25 X 135 -AB-M Pneumatic Rotary Actuator

Description:

The PHD RLS1 25 x 135 -AB-M Pneumatic Rotary Actuator is used in industrial automation systems to convert compressed air into controlled rotary motion for positioning, indexing, and part handling operations. It is commonly installed in packaging machines, assembly systems, conveyors, and automated production equipment where precise 135-degree rotational movement is required for repetitive mechanical positioning. Maintenance technicians and OEM machine builders use this actuator for motion control replacement, pneumatic system repair, and restoration of rotary positioning functions in automated machinery.

Applications:

The PHD RLS1 25 x 135 -AB-M Pneumatic Rotary Actuator is commonly used in PHD industrial automation systems, including PHD rotary indexing units, PHD material handling equipment, and PHD machine automation assemblies. It is also used in packaging machinery, assembly lines, conveyor positioning systems, and robotic fixtures where controlled 135-degree rotation is required for clamping, indexing, or part transfer operations.
