This non‑pyrotechnic delay ignition igniter adopts electronic chips to replace traditional chemical pyrotechnic tips. Paired with matching electronic delay chips, it supports up to 500 units in parallel networking and delivers a maximum delay time of 16000 ms, realizing stable delayed ignition without pyrotechnic composition.

◆ Fabricated from high‑temperature alloy, its ignition chip prevents spontaneous combustion even under 300 °C storage for 3 minutes. It delivers a wide operating temperature range from ‑60 °C to 300 °C and meets IP67 waterproof rating.

◆ It provides superior immunity to static interference, stray current, RF interference and heavy vibration for reliable field operation.

Core Advantages

This mining‑grade electronic igniter integrates robust electronic delay control and strong field‑adaptability. It addresses common‑site pain points such as cable damage, long‑distance wiring and large‑quantity detonation demands for both underground and open‑pit mining blasting. Below are its core technical advantages:

1. Independent Delay Module: Built‑in electronic delay module. Even if the circuit wire gets broken during blasting operation, the unit will still execute firing according to the pre‑programmed sequence.
2. Long‑Range Extension Cable: Supports extension cable up to 1000 meters, adapting to long‑distance blasting layout in open‑pit and underground mining sites.
3. High‑Capacity Parallel Connection: Supports parallel connection of up to 500 igniters, enabling large‑scale simultaneous blasting for mining projects.
4. Adjustable Delay for Multi‑Unit Blasting: Provides adjustable delay time up to 12 seconds for 1‑500 igniters, flexible for diversified blasting‑hole layout requirements.
5. Resonance‑Avoidance Blasting Performance: Customizable delay times can be set according to different rock strata and rock hardness, effectively avoiding blasting‑induced resonance.

Core Advantages

1. 360‑Degree Full‑Coverage Ignition: 360‑degree blind‑spot‑free ignition design delivers enhanced ignition success rate.
2. Laser‑Welded Bridge‑wire Structure: Adopts laser welding process to achieve uniform resistance and consistent ignition performance across units.
3. Fully‑Automatic Crimping Process: Fully‑automatic crimping production ensures outstanding product‑to‑product consistency.
