Product Description: Brass plate is a widely used leaded brass with good mechanical properties and excellent machinability. It can withstand both cold and hot pressure processing, making it suitable for various structural parts in machining and stamping, such as gaskets and bushings. Tin brass plate offers high corrosion resistance and good mechanical properties, with excellent pressure processability in both cold and hot states. It is used for corrosion-resistant parts on ships and components and conduits in contact with media like steam and oil.CharacteristicsBrass is an alloy of copper and zinc. Simple brass is a binary alloy of copper and zinc, known as simple brass or common brass. Varying the zinc content in brass alters its mechanical properties. Higher zinc content in brass increases its strength but slightly reduces plasticity. Industrially used brass contains no more than 45% zinc, as higher zinc content leads to brittleness and deteriorates alloy performance. To enhance specific properties, other alloying elements are added to binary brass, resulting in special brass. Common alloying elements include silicon, aluminum, tin, lead, manganese, iron, and nickel. Adding aluminum to brass improves yield strength and corrosion resistance while slightly reducing plasticity. Brass with less than 4% aluminum exhibits good comprehensive properties in processing and casting. Adding 1% tin to brass significantly enhances its resistance to seawater and marine atmospheric corrosion, hence the term "naval brass." Tin also improves the machinability of brass. The primary purpose of adding lead to brass is to enhance machinability and wear resistance, with little effect on strength. Manganese brass offers good mechanical properties, thermal stability, and corrosion resistance. Adding aluminum to manganese brass further improves its properties, resulting in castings with a smooth surface. Brass can be categorized into cast and pressure-processed products.H62 brass plate is primarily an alloy of copper and zinc with a wide range of applications. Its properties depend on the ratio of copper to zinc. H62 brass plate with over 63% copper can be cold-worked, annealed, and is ductile. Alloys with less copper and more zinc require hot working and exhibit higher strength. more>

Product Description: Feature Overview V25-B_FS, V25-B+C/FS, V20-C/FS Usage AdvantagesFloating Conversion Contact Transfer Contact PointAllows arbitrary selection of monitoring device signalsModular Structure (Only One Switch)Optional Normally Open or Normally Closed Connection ContactsSeparation Between Fs Module and Surge Arrester ModuleNo additional wiring required, saves timeAvoids mutual interferenceFunction and Application AreasThe Fs Remote Signaling Alarm Device is primarily used for centralized monitoring of surge protection devices installed in unattended or hard-to-inspect locations. Through the OBO Fs Remote Signaling Alarm Device, even from the control center, it is easy to understand the working status of the surge arrester.Each surge protection device with Fs functionality is equipped with a monitoring module that continuously checks the working status of all connected surge protection modules. If a surge protection module fails, the mechanical device sends a command to the micro-switch inside the Fs monitoring module. Then, the normally open and normally closed contacts inside the monitoring module switch to normally closed and normally open, respectively, and send the fault information to a remote display or sound device.The OBO Surge Protector V 25-B+C not only withstands high lightning current capacity but also features low protection voltage, making it suitable for use as a combined B+C protector.InstallationThe Fs device and surge protector are combined. During installation, simply fix them together onto any standard 35mm rail. The use of screwless crimp terminals makes wiring particularly convenient during engineering.Technical ParametersOBO V25-B+C/FS or V20-C/FS Remote Signaling Alarm DeviceMaximum Switching Voltage U～maxMaximum Switching Current I～maxConnection Wire Cross-Section250V6A0.14-2.5mm2Connection Cable Strip LengthSignal Contact No (Normally Open)Nc (Normally Closed)Installation6-7mm1-21-3Installed on 35mm standard rail, compliant with DIN EN 50022 more>
