LUX-No.1 Electronic Detonator(fire cracker) is a high security, high-precision, wide delay range, and programmable electronic detonator, which has independent intellectual property rights in China. It has a two-line system with two-way non-electrode net group communications and hole-line programming capability. It can achieve wide range of small interval delay data hole set. And it has good accurate initiation. Detonators state can be tested online; delay time can also be calibrated online, and it has initiation network with high reliability. Product serial number and initiation password are set in detonators, which are embedded anti-jamming isolation circuit. It is a safety-use, easy network design and convenient operation product. 1. Programmable delay time range: 0 15.000ms. 2. The smallest time interval of the delay program: 1ms 3. Delay time precision: 0.1% 4. Production enterprise code, product serial number and initiation password are all set in detonators. 5. Two-line system of two-way non-electrode net group communications. 6. On-line detection for detonators, and realizing reliable trouble-free initiation. 7. Embedded anti-jamming isolation circuit, and 15KV antistatic. 8. Anti-AC220V/50Hz, DC50V AC/DC initiation. 9. Waterproof, temperature, anti-vibration. 10. Temperature: -20 +70 11. Structure size (tube): Φ7.3*73mm
