Description
Heavy duty tunnel access, push-pull linear motion feedthroughs allow linear displacement of heavy samples and components. The push-pull shaft is hollow providing tunnel access for instrumentation leads such as those used for thermocouple temperature measurements and other low voltage electrical applications. The vacuum nose piece is shipped with a blank 1-1/3" Del-Sealº CF mini flange which can be removed or modified to accept electrical feedthroughs as required. These devices do not provide position indication. Sample or component position must be verified visually through a viewport. Sample linear position can be fixed with an integral position lock knob mounted on the actuator housing. Unlike conventional motion feedthroughs, heavy duty models employ reentrant welded bellows construction allowing the use of sturdier and larger diameter shafts. Models with two-, four- and six-inch maximum travel are offered on 2-3/4" Conflat® compatible Del-Sealº CF metal seal flanges.
