  • Piezo Buzzer - PAC-PT-2309-P
    PAC-PT-2309-P : Piezo Buzzer
    Features:
    The standard series are based on the highest piezo technology and are considered as most robust series for industrial applications. The standard buzzers use a special shaped membrane (curved edge), which is fixed and glued into the housing. They are shock proof, as well as dust. The different standard models cover a wide range of applications, offering functions such as continuous, intermittent, sweep and warbler, with a sound output more than 100 dB.

    All standard buzzers are available with various mounting methods, such as PCB or panel mounting and therefore are equipped with either pins or fast-on terminals. The standard series include military models, extra loud types, as well as models operating at very low voltage consumption (SC0715BL at 0.7V) and very low current (SP27 = 4,8 mA at 9V).

  • Piezo Transducer - PAC-PT-2707-P
    PAC-PT-2707-P : Piezo Transducer
    Features:
    The at accumulates in certain solid materials (such as crystals, certain ceramics, and biological matter such as bone, DNA and various proteins) in response to applied mechanical stress. The word piezoelectricity means electricity resulting from pressure. It is derived from the Greek piezo or piezein (πιζειν), which means to squeeze or press, and electric or electron (λεκτρον), which means amber, an ancient source of electric charge. Piezoelectricity was discovered in 1880 by French physicists Jacques and Pierre Curie.
    The piezoelectric effect is understood as the linear electromechanical interaction between the mechanical and the electrical state in crystalline materials with no inversion symmetry. The piezoelectric effect is a reversible process in that materials exhibiting the direct piezoelectric effect (the internal generation of electrical charge resulting from an applied mechanical force) also exhibit the reverse piezoelectric effect (the internal generation of a mechanical strain resulting from an applied electrical field). For example, lead zirconate titanate crystals will generate measurable piezoelectricity when their static structure is deformed by about 0.1% of the original dimension. Conversely, those same crystals will change about 0.1% of their static dimension when an external electric field is applied to the material. The inverse piezoelectric effect is used in production of ultrasonic sound waves.
    Piezoelectricity is found in useful applications such as the production and detection of sound, generation of high voltages, electronic frequency generation, microbalances, to drive an ultrasonic nozzle, and ultrafine focusing of optical assemblies. It is also the basis of a number of scientific instrumental techniques with atomic resolution, the scanning probe microscopies such as STM, AFM, MTA, SNOM, etc., and everyday uses such as acting as the ignition source for cigarette lighters and push-start propane barbecues.

  • Signal Receiver - PAC-RC-1206
    PAC-RC-1206 : Signal Receiver
    Features:
    Connecting a speaker to a receiver or amp is simple because there are only two wires, positive and negative, or plus and minus. Still, there is a 50% chance of getting it wrong, which can seriously affect system performance, so it pays to make sure the connections are correct. All receivers and speakers have a positive (+) and a negative (-) terminal (or connector) on the back for connecting wires.
    The positive terminal is usually red and the negative is typically black. (Note: speakers that are bi-wire capable will have four connectors, two red and two black). Speaker wires and connectors are usually marked with a + or – and some are color coded for easy identification. If not, identify the + and – on the wires with a piece of tape or a permanent marker.

  • Video Signal Receiver - PAC-RC-1506
    PAC-RC-1506 : Video Signal Receiver
    Features:
    In radio communications, a radio receiver is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna intercepts radio waves (electromagnetic waves) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information. The receiver uses electronic filters to separate the desired radio frequency signal from all the other signals picked up by the antenna, an electronic amplifier to increase the power of the signal for further processing, and finally recovers the desired information through demodulation.
    The information produced by the receiver may be in the form of sound (an audio signal), images (a video signal) or data (a digital signal). A radio receiver may be a separate piece of electronic equipment, or an electronic circuit within another device. Devices that contain radio receivers include television sets, radar equipment, two-way radios, cell phones, wireless computer networks, GPS navigation devices, satellite dishes, radio telescopes, bluetooth enabled devices, garage door openers, and baby monitors.
    In consumer electronics, the terms radio and radio receiver are often used specifically for receivers designed to reproduce the audio (sound) signals transmitted by radio broadcasting stations – historically the first mass-market commercial radio application.

  • Piezoelectric Transducers - PAC-ST-0503-P
    PAC-ST-0503-P : Piezoelectric Transducers
    Features:
    Today AV receivers are a common component in a high-fidelity or home-theatre system. The receiver is generally the nerve centre of a sophisticated home-theatre system providing selectable inputs for a number of different audio components like record players, compact-disc players and CD-RW recorders, and tape decks (like video cassette recorders (VCR) and video components (DVD players and DVD recorders, video game consoles, and television sets).
    With the decline of gramophone record vinyl discs, modern receivers tend to omit inputs for phonograph turntables, which have separate requirements of their own. All other common audio/visual components can use any of the identical line-level inputs on the receiver for playback, regardless of how they are marked (the "name" on each input is mostly for the convenience of the user). For instance, a second CD player can be plugged into an "Aux" input, and will work the same as it will in the "CD" input jacks.
    Some receivers can also provide digital signal processors (DSP) to give a more realistic auditory illusion of listening in a concert hall. Digital audio S/PDIF and USB connections are also common today. The home theater receiver, in the vocabulary of consumer electronics, comprises both the 'radio receiver' and other functions, such as control, sound processing, and power amplification. The standalone radio receiver is usually known in consumer electronics as a tuner.
    Some modern integrated receivers can send audio out to seven loudspeakers and an additional channel for a subwoofer and often include connections for headphones. Receivers vary greatly in price, and support stereophonic or surround sound. A high-quality receiver for dedicated audio-only listening (two channel stereo) can be relatively inexpensive; excellent ones can be purchased for $300 United States or less. Because modern receivers are purely electronic devices with no moving parts unlike electromechanical devices like turntables and cassette decks, they tend to offer many years of trouble-free service. In recent years, the home theater in a box has become common, which often integrates a surround-capable receiver with a DVD player. The user simply connects it to a television, perhaps other components, and a set of loudspeakers.
