1. 1. [] Made of brass and ceramic, temperature, more stable and long service life. 2. 2. [Size] Piezo pickup plate with thickness in 0.4mm, small, thin and lightweight. 3. 3. [High performance] Resonant frequency 4.6 +/- 0.5 kHz, resonance impedance 300 ohms max, low power consumption and high sensitivity. 4. 4. [Easy to use] These piezo pickups before wiring are easy to install and use in cigar box guitars, foot stoppers and other homemade instruments for detecting sound and vibration. 5. 5. [Wide use] For beginners, it can be made as touch sensors, electronic drum triggers, buzzers, own microphones, which are also used for watches, cameras, phones, electronic toys, computers, etc. (Optional) Material: brass. Thickness: 0.4 mm thick. Resonance frequency: 4.6 ± 0.5 kHz. Resonance impedance: 300 ω max. Package weight: 50g/70g/70g Package size: 15 x 10 x 5 cm.

• Premium durability: These piezo pickups combine brass coating with ceramic discs designed for temperature (-20°C to + 70°C) and 5000+ impact cycles. Ideal for high vibration instruments such as stomp boxes and drum kits.
• Ultra-thin design: The 0.4 mm thickness (equivalent to 3 stacked credit cards) allows seamless mounting on curved surfaces without the acoustic resonance. Each 35mm disc weighs under 2g for a minimum load.
• Precision performance: With 4.6 ± 0.5 kHz resonant frequency and ≤ 300 Ω impedance, these pre-wired sensors detect subtle vibrations from guitar bridges to mechanical wear monitoring in electronics.
• Plug and play installation: 10 inch (25 cm) prepared cables allow direct connection to 1/4 sockets or breadboards.
• Versatile with multiple applications: Use as: ① DIY drum trigger ② Guitar pickups from cigar box ③ Vibration alarms for doors/windows ④ Feedback sensors in robotics ⑤ MICS for unconventional sound design.
