Filed:

Dec 28, 2001

Appl. No.:

10/033413

Inventors:

William Eaton - Brooklyn Park MN
Roger J. Saba - Champlin MN

Assignee:

Turck Inc. - Plymouth MN

International Classification:

H05K 506

US Classification:

174 523, 73493, 7351416

Abstract:

A housing for protectively shielding control sensors detectors, or similar devices from harsh work environments. The housing comprises an enclosure having a sensing area transparent to electromagnetic waves. The sensing area is protected by a material that is arranged in an overlaying relation thereto, and which is of sufficient thickness to effectively protect the sensing area of the housing from harsh work environments while allowing the control sensor to operate therethrough in a normal fashion. The protective material may take the form of a laminate applied to a cap covering the sensing area, or the cap itself and/or housing may be made from the protective material. Preferably, the protective material includes material having a low coefficient of friction such as molybdenum disulfide, graphite, or polytetrafluoroethylene.

Appl. No.:

11/686613

Inventors:

William Eaton - Brooklyn Park MN, US

International Classification:

B23K 9/32

US Classification:

3406866, 3406935

Abstract:

A protective cover for a sensing surface of a control sensor/proximity detector. The protective cover comprises a material having a preferred shore-A durometer hardness in the range of 60-90, a preferred tensile strength of 1320 psi (92.82 kilogram-force per square centimeter (kgf/cm2)) or greater, a preferred dielectric strength of around 300 volts/mil, and a preferred thermal conductivity of 0.3 to 0.5×10cal/sec, and a temperature stability of about −55 to +200 degrees Celsius. The protective cover may be adhesively secured to the proximity detector so that the sensing surface is effectively covered. The protective cover may be in the form of a sheet or may be in the form of a cap. Preferably, the protective cover comprises silicone material.

Abstract:

An angular displacement sensor for determining the location of a rotating element such as a power clamp, fixedly attached to the power clamp adjacent the clamp arm. Specifically, the angular displacement sensor includes a rotating portion within a stationary housing, the rotating portion being directly connected to the axle that attaches the clamp arm to the connecting rods driven by the piston. By sensing the position of the rotating portion of the angular displacement sensor, which is directly connected to the axle and thereby rotates in direct proportion to the movement of the clamp arm, the sensor may easily determine the position of the clamp arm.
