Pilz (company)
Pilz GmbH & Co. KG is a German automation technology company headquartered in Ostfildern, Germany, with 42 subsidiaries and branches on all continents. The company was founded as a glass-blowing business by Hermann Pilz in Esslingen in 1948. Initial products included glass apparatus for medical technology and mercury relays for industrial applications. In the 1960s control passed to Pilz' son Peter, who developed the company into a supplier of electronic control and monitoring devices and programmable logic controllers. In 1987 he launched safety relay PNOZ, an emergency stop A kill switch, also known more formally as an emergency brake, emergency stop (E-stop), emergency off (EMO), or emergency power off (EPO), is a safety mechanism used to shut off machinery in an emergency, when it cannot be shut down in the usu ... system. PSS control systems were developed in the 1990s. Other products and services include sensor technology, bus and industrial wireless systems, risk a ...

Ostfildern
Ostfildern (; Swabian German, Swabian: ''Oschtfilder'') is a town in the Esslingen (district), district of Esslingen in Baden-Württemberg in southern Germany. It is located approximately 8 km southeast of Stuttgart. It was formed in 1975 out of a fusion of the previously separate boroughs of Nellingen (including Parksiedlung), Ruit, Kemnat and Scharnhausen and currently has approximately 37,000 inhabitants. Geography Ostfildern is situated in the east of the Filder area, a fertile plateau south of Stuttgart. It is bordered to the south by the Körsch river, which flows into the Neckar. History The town of Ostfildern was formed on 1 January 1975 from the fusion of the formerly independent boroughs of Nellingen, Ruit, Kemnat and Scharnhausen. From 1945 to 1992 the United States Army, U.S. Army operated Nellingen Kaserne as a barracks and airfield. The site has since been redeveloped as Scharnhauser Park. A well-known inhabitant of Ostfildern is Abdul Ahad Momand, who was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germany
Germany, officially the Federal Republic of Germany, is a country in Central Europe. It lies between the Baltic Sea and the North Sea to the north and the Alps to the south. Its sixteen States of Germany, constituent states have a total population of over 84 million in an area of , making it the most populous member state of the European Union. It borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The Capital of Germany, nation's capital and List of cities in Germany by population, most populous city is Berlin and its main financial centre is Frankfurt; the largest urban area is the Ruhr. Settlement in the territory of modern Germany began in the Lower Paleolithic, with various tribes inhabiting it from the Neolithic onward, chiefly the Celts. Various Germanic peoples, Germanic tribes have inhabited the northern parts of modern Germany since classical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercury Relay
A mercury relay (mercury displacement relay, mercury contactor) is a relay that uses mercury as the switching element. They are used as high-current switches or contactors, where contact erosion from constant cycling would be a problem for conventional relay contacts. Owing to environmental considerations about the toxicity of mercury, mercury relays are mostly obsolete, though modern encapsulated units still have applications. They are generally being replaced by solid state relays. Operation Mercury relays consist of a vertical (usually glass) tube containing liquid mercury. They have isolated contacts at the bottom of the tube and partway up, usually in a side arm of the glass. The relay works by displacement. A pool of mercury fills the lower portion of the tube, but is insufficient to bridge the contacts. A magnetic slug of iron or steel is placed in the tube, where it sinks by gravity so as to displace the mercury. The displaced mercury rises in the tube, sufficiently ...

Safety Relay
Safety relays are devices that generally implement safety functions. History Relays and contactors were used to control plant and machinery in the early days of control technology. In the event of a hazardous situation, the actuator was simply isolated from the energy supply. This type of protection system could be manipulated in the event of a malfunction, disabling the protective function. Special relay circuits, such as the three-contactor combination, were the first designs to come out of deliberations into how this could be avoided. These device combinations led to the development of the first safety relay from the German automation manufacturer Pilz, the PNOZ. Description In the event of a hazard, the task of safety functions (e.g. E-STOP, safety gate or standstill monitoring) is to use appropriate measures to reduce the existing risk to an acceptable level. These many safety functions include: * Emergency stop pushbuttons * Safety gates * Light beam devices * Pres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Stop
A kill switch, also known more formally as an emergency brake, emergency stop (E-stop), emergency off (EMO), or emergency power off (EPO), is a safety mechanism used to shut off machinery in an emergency, when it cannot be shut down in the usual manner. Unlike a normal shut-down switch or shut-down procedure, which shuts down all systems in order and turns off the machine without damage, a kill switch is designed and configured to abort the operation as quickly as possible (even if it damages the equipment) and to be operated simply and quickly (so that even a panicked operator with impaired executive functions or a bystander can activate it). Kill switches are usually designed to be noticeable, even to an untrained operator or a bystander. Some kill switches feature a removable, protective barrier against accidental activation (e.g. a plastic cover that must be lifted or glass that must be broken), known as a mollyguard. Kill switches are features of mechanisms whose normal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electronics Companies Of Germany
Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other electrically charged particles. It is a subfield of physics and electrical engineering which uses active devices such as transistors, diodes, and integrated circuits to control and amplify the flow of electric current and to convert it from one form to another, such as from alternating current (AC) to direct current (DC) or from analog signals to digital signals. Electronic devices have significantly influenced the development of many aspects of modern society, such as telecommunications, entertainment, education, health care, industry, and security. The main driving force behind the advancement of electronics is the semiconductor industry, which continually produces ever-more sophisticated electronic devices and circuits in response to global demand. The semiconductor industry is one of the global e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
