Customer part number marked on request. Unless specified otherwise, all tolerances are ± .015 ( 0,38) 240 hours (MIL-STD-202 Method 103, Test Condition A) Shaft and Panel Seal All switches are provided with a shaft and panel seal. OPTIONS Adjustable Stop Switches The switch may have continuous rotation, or be adjusted to limit the rotation. The panel seal ring can be removed to expose the stop pin holes on the front of the switch. Two stop pins and panel seal o-ring are supplied with the switch. One or both may be used to limit the rotation as desired. Custom encoders with options such as custom code output, 1/4” shaft diameter, factory set stops and longer shaft terminal lengths are available by contacting the Grayhill sales office at 708.482.2123.
