Vs = 2.0 V dc RL = 2.2K Ω signal to noise ratio (S/N) 57 dBA f = 1KHz, 1Pa A-weighted operating temperature -20 ~ +70° C storage temperature -20 ~ +70° C dimensions ø6.0 x 2.7 mm weight 0.22 g max. material Al terminal wire type (hand soldering only) RoHS yes dustproof and waterproof level IP57 note: We use the “Pascal (Pa)” indication of sensitivity as per the recomendation of I.E.C. (International Electrotechnical Commission). The sensitivity of “Pa” will increase 20dB compared to the “ubar” indication. Example: -60dB (0dB = 1V/ubar) = -40dB (1V/Pa) APPEARANCE DRAWING UL1571, 30AWG 0.2 6.0 2.7 0.2 Terminal 2 BLACK Terminal 1 RED 2.0 0.5 (2 PLCS) 25.0 3.0 (2 PLCS) MAX 4.1 tolerances not shown: ±0.3mm |
