OMTECs patented PUGs are designed for an easy solution to almost any ESD application. These simple yet effective units are placed in work surfaces that were not originally designed for ESD applications. The bottom if the unit has a threaded stud so it can be grounded. The top of the unit has a spring loaded brass pin that stays in contact with your product grounding it at all times even when the unit is retracted. When the units raised the brass pin retracts under little pressure but still remains in contact always grounding your ESD product. Virtually any air control device may operate Omtec PUG . In the majority of applications simple non electric foot and hand valves may be used. Sensing device operated electric solenoids valves may also be used. Omtec PUGs like virtually all pneumatically operated components, require Filtered, Regulated and Lubricated compressed air to operate. Omtec has FRL kits, Non-detent foot valve kits and detent toggle hand valve kits available. Other controls supplied on request. The regulator should be set at 50 PSI (3.447 bar). Omtec PUGs use very low air volume, it is usually not a consideration. Each up and down cycle of one ball uses .00038 cubic feet (.0000108 cubic meter). Carbide bits for boring and recessing holes in plastic wood composite surfaces. Omtec has available correct size carbide tipped bits to easily bore holes for Pop-Up Ball Transfers. 1/2 inch (13mm) hand drill required. If recessed flanges are desired, Omtec also has available the correct size carbide tipped rabbeting bits. 1/4 inch (6.35mm) trim routers. Minimum metal surface thickness: Steel 0.092 inches (2.34mm), Aluminum 0.125 inches (3.18mm). Depending on individual applications, ribbed reinforcement of all surfaces is an important consideration. Omtec PUGs? are designed to use in combination with all of the other Omtec Ergonomic Tranfers. They are ideal with Omtec: PPD Positioner Pads, FBT Ball Transfers, Insert Wheels, Insert Rollers and the PBTs Pop-Up Balls
