Buzzer mag 6v

ELECTRO MAGNETIC TRANSDUCER; PCB MOUNT 3-7V @ 30mA HOUSED; SELF-DRIVEN; D=16MM; PANEL HOLE-14MM

LilyPad Buzzer Wearable This is a small buzzer for the LilyPad system. Use pins on the LilyPad 2 I/O main board and create different noises based on the different frequency of I/O toggling. Loud enough to hear inside a pocket but not obtrusively loud. This is an inductive buzzer meaning that is will act as a short to ground if you are not actively driving it. We recommend you put both I/O pins to low (0V) when the buzzer is not used. Also, it's come to our attention that washing these buzzers will damage them. Until we've figured out a solution to this, avoid washing any portion of your project that contains one of these buzzers. Rated Voltage: 3.6V Operating Voltage: 2.5~4.5V Mean Current: Max 110mA Sound Output: Min 85dBA (90 Typ.) Distance at 10cm Rated Frequency: 2730Hz Operating Temperature: -30~±70°C Size: 20mm x 0.8MM PCB This item is available in stock and is not drop shipped. This avoids delays, customs charges and extra VAT.

Feature: Supply voltage: 3-5V Dimensions: 66 x 61MM Maximum detection range: 5CM (Best detection range: 1 CM - 2 CM) Principle explanation:   Q1, L1, L2, C2, C3, R1, W composed of high-frequency oscillation circuit, adjustment potentiometer W, you can change the oscillation stage gain, the oscillator oscillating in a critical state, that is just the oscillator start-up. Q2, Q3 when the composition of the detection circuit, the circuit normally oscillate voltage AC voltage exceeds 0.6V, Q2 will be in the negative half cycle of conducting the C4 discharge short circuit, resulting in Q3 ends; when it detects metal objects near the coil L1, will be metal conductor eddy current is generated, the oscillation circuit of the energy loss increases, positive feedback weakened in the critical state of the oscillator weakened, if not impossible to maintain the minimum required energy oscillations and to stop, so Q2 is turned off, R2 to C4 charge, Q3 is turned on, pushing the buzzer sounds. According to whether the sound, you can determine whether the detection coil underneath the metal object. Note: If you need longer detection range and higher sensitivity, please create their own search coil, search coil diameter of the larger suppliers will be farther away from the probe. Package included: 5 x DIY Metal Detector Kit
