Technology / Type
   Technology       
   Your choices are...         
   Electromagnetic       Electromagnetic transducers generate either a single continuous sound or intermittent tones. They are available with either self-contained or external drive circuitry. 
   Piezoelectric       Piezoelectric ceramic elements are sintered bodies made of many crystals. Crystal distortion occurs when thermal, mechanical, or electrical stress is applied to the ceramic element. These distortions offer many possible uses, including alarm and sensor applications. In audible output applications, a metal plate is attached to the ceramic element because the resonant frequency of the ceramic is too high to produce an audible tone by itself. The metal plate vibrates because of the contraction and expansion of the piezo ceramic, and an audible signal is produced. 
   Other       Other unlisted, specialized, or proprietary technologies. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   RoHS / Lead-Free Compliant       Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl ether. RoHS became effective on July 1, 2006. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

Physical Specifications
   Shape       
   Your choices are...         
   Round       Devices are round and shaped like a small cylinder. 
   Square / Rectangular       Devices are square or rectangular. 
   Other       Other unlisted, specialized, or proprietary shapes. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Terminations       
   Your choices are...         
   None (SMT)       Devices do not include terminations. The element is surface-mounted and connected by wave solder. 
   Leads       Devices have pre-wired leads or pigtails. 
   PC Pins       Multi-pin connectors are used primarily for external interfacing.  Typical applications include measuring equipment, industrial sensors, industrial equipment and machines, computers and peripherals, medical equipment, and audio and video equipment. 
   Quick Connects       Quick connects or convenience connectors are plugs used with sensor probes. 
   Screw Terminals       Devices allow for electrical connections via screw terminals. 
   Solder Tabs       Solder tabs are flat, metal pieces to which wires can be soldered. They are used to attach devices to circuit boards. 
   Other       Other unlisted, specialized, or proprietary terminations. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Mounting       
   Your choices are...         
   Panel Mount       Devices mount on a panel and may be flush or flanged. They have a partially threaded body and a matching nut. 
   Socket Mount       Devices plug into a receptacle, typically an IC-type socket. 
   Surface Mount       Surface mount technology (SMT) adds components to a printed circuit board (PCB) by soldering component leads or terminals to the top surface of the board. SMT components have a flat surface that is soldered to a flat pad on the face of the PCB. Typically, the PCB pad is coated with a paste-like formulation of solder and flux. With careful placement, SMT components on solder paste remain in position until elevated temperatures, usually from an infrared oven, melt the paste and solder the component leads to the PCB pads.   Industry-standard pick-and-place equipment can mount SMT components quickly, accurately, and cost-effectively. SMT is a widely used alternative to mounting processes that insert pins or terminals through holes and solder leads into place on the opposite side of the board. 
   Screw Down       The transducer body has flanges with holes that allow the device to be screwed down. 
   Other       Other unlisted, specialized, or proprietary mountings. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Frame Diameter / Length       If the device is round, this measurement is the diameter. If the device is square or rectangular, this measurement is the largest dimension. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Frame Depth       This is the device's depth or thickness. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Audio Specifications
   Tone:       
   Your choices are...         
   Continuous       The tone of the alarm is continuous. 
   Non-continuous       The tone of the alarm is pulsed or non-continuous. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Frequency       Frequency is the number of events or cycles that occur in a time period, usually one second. Frequency is measured in Hertz (Hz). 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Sound Pressure Level       Sound pressure level (SPL), an expression of loudness or volume, is measured in decibels (dB). A 10-dB increase in SPL represents a doubling in volume. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Features
           
   Your choices are...         
   Volume Control Option       A shutter-like device rotates to allow more or less sound from the transducer. 
   Programmable       Devices are programmable or adjustable and provide for different ranges, materials, levels, outputs, etc. 
   Visual Alarm       Visual alarms warn personnel who work in areas with high noise levels, and who may not be able to hear audible alarms. 
   Externally Driven       External drive circuitry transducers have a single coil and a magnetic circuit composed of a permanent magnet, an iron core, a highly permeable metal disk, and a vibrating diaphragm. The disk and diaphragm are attracted to the core by the magnet's magnetic field. When an oscillating signal moves through the coil, it creates a fluctuating magnetic drive that vibrates the diaphragm at the drives signal's frequency. A sound is produced based on the frequency applied. 
   Internally Driven       Transducers with self-contained drive circuitry have inductively coupled coils. This type of transducer produces an average sound output of 85 dB or 10 cm/min. 
   Other       Other unlisted, specialized, or proprietary features. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
