The total clamping force and the force distribution along the guide is an important consideration when selecting the proper guide. Figure 1. shows the clamping force (perpendicular to guides long axis) upon first actuation. All guides were torqued to the recommended value of 115 in-oz unless otherwise indicated. Values are for a single guide. All surfaces were cleaned with alcohol and no lubricants were used. Five-piece wedge-loks provide more force more evenly than three-piece wedge-loks. The performance of screw actuated guides will degrade with subsequent actuations due to normal thread wear. Lever actuated guides are sensitive to board thickness and/or slot width variation (see Figure. 3) whereas screw actuated guides provide a constant force over a wider operating range. Products & Services
Light guides conduct the flow of light from a light source to a point of use in areas that are too small or too hazardous to permit the installation of a light bulb. There are two basic types of light guides: liquid and fiber optic.
Industrial knobs are small, usually round, devices that are designed for use on industrial machinery, electronic components, and metal cabinetry. They are usually made out of metal, plastic, or rubber and are available in a variety of sizes, colors, and finishes.
Guide and drill bushings are used to guide drills, punches, pillars or other tools.
Mechanical clutches are assemblies consisting of elements for the connection and disconnection of shafts (clutch) in equipment drives.
Card guides are attached to backplane motherboards to allow the insertion or mounting of computer cards.
