altPHD (Fort Wayne, IN) has introduced the Series PLM pin locating clamp, a pneumatically powered actuator to locate, clamp, and support parts in welding applications. To protect against slag and other contaminants, the clamp is fully enclosed. A built-in locking mechanism fixes the pin in any position to secure parts if air pressure is removed. A manual part release is standard. Part support height adjusts with NAAMS™ shims. Position sensing provides open or closed sensing with industry standard AC or DC weld field immune switches mounted in a protected housing for consistent position sensing. Pin sizes are available in 13, 16, 20, and 25 mm.
