ravel, aggregate of more or less rounded rock fragments coarser than sand (i.e., more than 2 mm [0.08 inch] in diameter). Gravel beds in some places contain accumulations of heavy metallic ore minerals, such as cassiterite (a major source of tin), or native metals, such as gold, in nuggets or flakes. Gravels are widely used building materials. Fragments in gravel range in size from pebbles (4–64 mm [0.16–2.52 inches] in diameter), through cobbles (64–256 mm [2.52–10.08 inches]), to boulders (larger than 256 mm). The rounding of gravel results from abrasion in the course of transport by streams or from milling by the sea. Gravel deposits accumulate in parts of stream channels or on beaches where the water moves too rapidly to permit sand to remain. Because of changing conditions, gravel formations generally are more limited and more variable in coarseness, thickness, and configuration than sand or clay deposits. Persistent accumulation of gravel or pebble beds may take place along an inner zone of breaking waves, on a beach that is otherwise sandy. Cobble and pebble beaches (shingle beaches) often originate from the points of rocky cliffs. In many regions marine gravels similar to those of the seashore exist tens or hundreds of metres above tide level; such gravel terraces (or raised beaches) may extend great distances and indicate that the sea at one time stood relatively higher. River gravels occur mostly in the middle and upper parts of streams where the currents are swiftest. Ancient gravel terraces found at levels much above those of the present rivers mark former streams or are evidence of uplift of the land or lowering of the sea.

Our Activated carbon is used to an increasing extent in the treatment of water, including drinking water, ground-water, service water and waste water. Its primary role in this context is to adsorb dissolved organic impurities and to eliminate substances affecting odor, taste and color in halogenized hydrocarbons and other organic pollutants. Yet another broad field of application for activated carbon is the treatment, purification and decolourisation of liquids, which is of particular importance in the pharmaceuticals, food, beverage and other allied industries.

This Harmony XB5N/XB7N, modular red push button operates with a spring return / impulse mechanism and uses screw clamp terminals. This push button provides a simple and robust control to machines and processes. It is easily installed into standard 22mm diameter cut-outs and connected with simple screw-clamp connections. Its schematic is clearly distinguishable visually at a distance thanks to clear colors and markings, minimizing errors during initial wiring and later maintenance operations. It is impact resistant, dust resistant, water resistant and vibration resistant, making it ideal for operation in harsh environments. Its plastic bezel makes it ideal for applications requiring good resistance to chemical agents and/or double electrical insulation.   Main Range of product Harmony XB5N/XB7N Product or component type Push-button Device short name XB5N Product compatibility ZB5...N Bezel material Dark grey plastic Head type Standard Fixing collar material Plastic Mounting diameter 22.5 mm Sale per indivisible quantity 20 Shape of signaling unit head Round Type of operator spring return Operator profile Red flush, unmarked Contacts type and composition 1 NO Contact operation Slow-break Connections - terminals Screw clamp terminals, <= 2 x 1.5 mm² with cable end conforming to IEC 60947-1Screw clamp terminals, >= 1 x 0.22 mm² without cable end conforming to IEC 60947-1 [Us] rated supply voltage 24 V AC/DC at 50/60 Hz Complementary Height 42 mm Width 30 mm Depth 52 mm Terminals description ISO n°1 (13-14)NO Net weight 0.037 kg Device mounting Fixing hole - diameter: 22.5 mm 22.3 +0.4/0 conforming to IEC 60957-5-1 Fixing mode Fixing nut recommended torque: 2.2 N.m (+/- 0.2 N.m) Contacts usage Standard contacts Positive opening Without Operating travel 1.5 mm (NC changing electrical state)2.6 mm (NO changing electrical state)4.3 mm (total travel) Operating force 3.5 N NC changing electrical state3.8 N NO changing electrical state Mechanical durability 5000000 cycles Tightening torque 0.8…1.2 N.m conforming to IEC 60947-1 Shape of screw head Cross compatible with Philips no 1 screwdriverCross compatible with pozidriv No 1 screwdriverSlotted compatible with flat Ø 4 mm screwdriverSlotted compatible with flat Ø 5.5 mm screwdriver Contacts material Silver alloy (Ag/Ni) Short-circuit protection 10 A cartridge fuse type gG conforming to IEC 60947-5-1 [Ith] conventional free air thermal current 10 A conforming to IEC 60947-5-1 [Ui] rated insulation voltage 600 V (pollution degree 3) conforming to IEC 60947-1 [Uimp] rated impulse withstand voltage 6 kV conforming to IEC 60947-1 [Ie] rated operational current 3 A at 240 V, AC-15, A600 conforming to IEC 60947-5-10.55 A at 125 V, DC-13, Q600 conforming to IEC 60947-5-10.1 A at 600 V, DC-13, Q600 conforming to IEC 60947-5-10.27 A at 250 V, DC-13, Q600 conforming to IEC 60947-5-11.2 A at 600 V, AC-15, A600 conforming to IEC 60947-5-16 A at 120 V, AC-15, A600 conforming to IEC 60947-5-1 Electrical durability 1000000 cycles AC-15, 2 A at 230 V, operating rate <3600 cyc/h, load factor: 0.5 conforming to IEC 60947-5-1: appendix C1000000 cycles AC-15, 3 A at 120 V, operating rate <3600 cyc/h, load factor: 0.5 conforming to IEC 60947-5-1: appendix C1000000 cycles AC-15, 4 A at 24 V, operating rate <3600 cyc/h, load factor: 0.5 conforming to IEC 60947-5-1: appendix C1000000 cycles DC-13, 0.2 A at 110 V, operating rate <3600 cyc/h, load factor: 0.5 conforming to IEC 60947-5-1: appendix C1000000 cycles AC-13, 0.5 A at 24 V, operating rate <3600 cyc/h, load factor: 0.5 conforming to IEC 60947-5-1: appendix C Electrical reliability Λ < 10exp(-6) at 5 V and 1 mA in clean environment conforming to IEC 60947-5-4Λ < 10exp(-8) at 17 V and 5 mA in clean environment conforming to IEC 60947-5-4 Device presentation Complete product Customizable No Customizable 0 Compatibility code XB5 Environment Protective treatment TH Ambient air temperature for storage -40…70 °C Ambient air temperature for operation -25…70 °C Overvoltage category Class II conforming to IEC 60536 Standards IEC 60947-5-4IEC 60947-1IEC 60947-5-1IS 13947-5-1 Product certifications CE Vibration resistance 5 gn (f= 2…500 Hz) conforming to IEC 60068-2-6 Shock resistance 30 gn (duration = 18 ms) for half sine wave acceleration conforming to IEC 60068-2-2750 gn (duration = 11 ms) for half sine wave acceleration conforming to IEC 60068-2-27 Electromagnetic emission Class B conforming to IEC 55011 IP degree of protection IP65 IK degree of protection IK03 Packing Units Unit Type of Package 1 PCE Number of Units in Package 1 1 Package 1 Height 3.5 cm Package 1 Width 5.5 cm Package 1 Length 8.5 cm Package 1 Weight 28 g Unit Type of Package 2 BB1 Number of Units in Package 2 20 Package 2 Height 9 cm Package 2 Width 14 cm Package 2 Length 19 cm Package 2 Weight 644 g Unit Type of Package 3 S03 Number of Units in Package 3 240 Package 3 Height 30 cm Package 3 Width 30 cm Package 3 Length 40 cm Package 3 Weight 8423 g
