Patent number: 9455560Abstract: Disclosed is a wall mount enclosure and sealing assembly for electrical devices, the enclosure comprises a housing defining an interior that is accessible from an opening in a front side and configured to support electronic equipment therein. A closure door is operatively mounted to the enclosure in a closed position to prevent outside access through the opening in the front side, the closure door including an inwardly facing portion generally facing towards the front side around all or at least a portion of a periphery of the door, the inwardly facing portion extending laterally outward of the periphery of the opening. A gasket engages at least part of the inwardly facing portion of the closure door with a seal portion or first portion pressed by the inwardly facing portion of the closure door when the closure door is in the closed position to form a seal between the front side and the inwardly facing portion of the closure door to seal the interior of the enclosure.Type: GrantFiled: April 8, 2014Date of Patent: September 27, 2016Assignee: PEPPERL+FUCHS, INC.Inventors: Steve Jopek, Matthew W.

Patent number: 8839567Abstract: Disclosed is a wall mount enclosure for mounting in a wall, including a housing with a front side, a back side and at least one side wall defining an interior accessible from an opening in the front side, where the front side has an outer perimeter extending outwardly beyond the side wall to interface with a front surface of the wall when a plurality of clamping mechanisms are engaged to mount the enclosure to the wall. The clamping mechanisms comprise a threaded fastener having a head accessible through the interior, and an at least partially threaded elongated member. A clamp body is provided and is pivotal about an axis by pivoting the threaded fastener in a first direction away from the interior of the enclosure and linearly translatable when in a second pivotal position to engage a back portion of the wall and mount the housing.Type: GrantFiled: April 29, 2014Date of Patent: September 23, 2014Assignee: Pepperl+Fuchs, Inc.Inventors: Gary M.

Patent number: 7663377Abstract: Systems and methods are provided for sensing or measuring capacitive or inductive reactance or changes in reactance in which the sensed reactance is coupled with a known resistance in a sensor circuit and a start signal is provided to the sensor circuit, and a programmable delay line is used to generate a programmable delay signal.

Patent number: 5233231Abstract: A palm-button control system provides for machinery control with minimized operator hand pressure by use of capacitive switches and reduced susceptibility to radio frequency interference. The system employs first and second capacitive palm-button switches, both of which must be contacted before machinery is activated. Each capacitive palm-button includes a radio frequency sensor which functions to disable machine activation in the presence of a sufficiently strong radio signal. Circuitry for periodically testing the radio frequency sensors provides periodic visual operator feedback indicative of operability of the system. All controls are synchronized or enabled in accordance with a series of digital pulses.Type: GrantFiled: November 29, 1991Date of Patent: August 3, 1993Assignee: Pepperl + Fuchs, Inc.Inventors: Hermann Wieth, Hans-Jurgen Schiefer

Patent number: 5144517Abstract: An protection barrier provides voltage and current necessarily conveyed to hazardous, such as explosive, areas. The system includes a current sensing circuit which triggers a silicon control rectifier based crowbar circuit in the event over current is detected. This triggering, in turn, trips a relay severing the current path entirely. A reverse polarity circuit provides for immediate clamping of improperly bias connections in a similar crowbar arrangement, and also provides for tripping of the circuit breaker. Thermistors are also provided in current series in the event the circuit breaker fails to trip, or is forcibly bypassed. The circuit breaker additional provides a visual indicator when it is in the tripped position. The intrinsic barrier system is suitable to serving as a first stage protection to zener barrier modules as utilized in the prior art.Type: GrantFiled: August 12, 1991Date of Patent: September 1, 1992Assignee: Pepperl + Fuchs, Inc.Inventor: Hermann Wieth
