Cell phone jammer also blocks invisible earphones

Conductive silicone rubber is mixed in copper, silver, silver-plated copper, silver and silver-plated aluminum glass powders and so on. One glass silver series of recommended levels in commercial and general military use; copper, silver series of electromagnetic shielding performance, and can be resistant to electromagnetic pulse impact, it is recommended to use high-end military; aluminum silver series of electromagnetic shielding performance, and electrochemical properties of aluminum compatible and can be resistant to electromagnetic pulse impact, the project recommended in the military material used on the aluminum chassis; Besides cell phones, LRZT-9.1HH cell phone jammer also blocks invisible earphones.Silver Series mold, can be used in the microbial growth conditions; Tanhei series applies to electrostatic discharge and corona discharge of the occasion; graphite silver series of lower prices, but also compatible with the electrochemical properties of aluminum, with the military in general. Conductive rubber surface is relatively soft, can not pierce the surface of the metal oxide layer, so that the shielding effectiveness is very low. The overall hard conductive rubber, with worse performance than the metal. Conductive adhesive and elastic rubber seal can be flexible. Conductive rubber gasket cross-section 393) conductive fabric gaskets:Besides cell phones, LRZT-9.1HH cell phone jammer also blocks invisible bone conduction earphones. Conductive fabric made of copper, copper nickel, copper and black resin made of a conductive woven fiber, conductive non-woven fibers and several types of conductive wire mesh, with soft , air permeability, compressibility, elasticity and light transmission characteristics. Conductive fabric wrapped foam rubber conductive cloth pad (see Figure), with a flexible, compression and other features. For there is a big gap tolerances of general-purpose electromagnetic shielding facilities. Flexibility and adaptability of the bubble, making it the required low pressure sealing and low compression ideal. In 2 0 MHz ~ 10GHz frequency range up to more than 100dB of shielding effect. Corrosion of the nickel coating with excellent electrochemical compatibility. Pressure-sensitive adhesive and rigid fixtures to ensure close contact between the contact surfaces. Besides cell phones, LRZT-9.1HH cell phone jammer also blocks rubbers.Common conductive cloth pad shape 404) finger guard: a durable metal bar. Because of excellent flexibility, can be closed in the low pressure equipment to provide high performance (either high or low frequency). Often used in electromagnetic interference, electromagnetic or electrostatic discharge protection device requirements. In particular, the contact surface for sliding contact applications. The material is beryllium copper, not burn, but also from the impact of UV rays and stable performance, can choose a variety of coatings to ensure that the contact surfaces with the electrochemical performance of other compatible, they are able to adapt to the needs of a variety of work environments . Refers to the shape deformation of large reed; low and high frequency shielding performance is also better. CD prices high. Figure finger is common reed outline. Common reed finger Outline 41 Ⅵ. Electromagnetic gasket installation here cite two relatively more use of metal mesh liner and finger reed installation cases. ⑴ used to install wire mesh wire mesh liner liner sections are often rectangular or circular. Besides cell phones, LRZT-9.1HH cell phone jammer also blocks rulers.Figure A is a rectangular pad in one of the installation method, it is placed between the metal plate XX and YY, through which the formation of a low impedance path. A better method of installation shown in Figure b, liner compression of the XX and YY return to their mechanical contact. Therefore, XX and YY are close together, so that the gap is unlikely to produce leakage, gasket at the seams and PETE good electrical contact.
