GTIN Standard 4052568000745

Technical Overview

The Festo AR-01 is a precision-engineered roller lever designed as a mechanical actuating component for valve assemblies. Part of the VAOM series, this actuator attachment features a robust galvanised steel mounting adaptor and is designed for reliable mechanical operation with a defined actuating force of 10 N. It meets the VDMA24364-B1/B2-L standard for LABS (PWIS) conformity, ensuring it is safe for use in applications sensitive to paint-wetting impairment substances.

Industrial Applications

1. Automotive Paint Shop Conveyor Skid Detection

Implementation of the AR-01 roller lever as a mechanical limit switch attachment for pneumatic valves within a vehicle body painting line. The roller lever physically contacts the passing skid or carriage to trigger the next stage of the spray process without using electrical sensors.

Problem Solved

Standard electrical sensors pose explosion risks in solvent-heavy spray booths and often contain silicone or contaminants that cause paint defects (cratering). The AR-01 provides a purely pneumatic, spark-free sensing solution that is certified free of paint-wetting impairment substances.

2. Woodworking Machine Pneumatic Clamp Sequencing

Integration of the AR-01 attachment onto a stem-actuated valve in a dusty furniture assembly rig. As the primary clamp cylinder extends, a cam strikes the AR-01 roller lever, mechanically opening the valve to pilot the secondary drill feed cylinder.

Problem Solved

Fine wood dust creates an insulating layer that frequently blinds optical sensors or jams electromechanical microswitches. The AR-01's robust mechanical roller action and 10 N actuating force cut through dust buildup, ensuring reliable sequencing where electronic alternatives fail.

3. Volatile Chemical Filling Lance Safety Interlock

Deployment of the AR-01 on a pneumatic interlock valve for a drum filling station handling flammable solvents. The roller lever detects when the filling lance is fully lowered and seated, permitting the main flow valve to open only when physical contact is maintained.

Problem Solved

Eliminates the need for expensive ATEX-rated explosion-proof electronics in a Zone 1 hazardous area. The steel galvanised construction ensures durability against rough handling of the lance, while the mechanical actuation removes any ignition source.
