Star Micronics introduces the NFT-03A, a surface mount audio alert. The NFT-03A delivers high SPL so it can be heard in noisy environments. The NFT-03A's 80 dB average SPL delivers a warning type tone that is attained, in part, due to an internal cavity structure, that eliminates the need for an externally designed cavity. The NFT-03A contains no lead materials (Pb free) nor does it have any adhesives available. The NFT-03A has a rated voltage of 3 V and an operating voltage range of 4.0 V (maximum). Reference frequency is 4000 Hz and coil DC resistance is 17 +3 Ω.
