SKH086M -Heavy Machinery Flame Sensor

  • Designed to detect fires early in harsh environments with dust, high temperatures, and heavy machinery or waste materials, helping prevent accidents before they occur.
  • Preventing Engine Fires Caused by Dust
    Detects ultraviolet (UV) rays emitted by flames inside the engine room of heavy
    machinery. Alerts the operator with an alarm to take immediate action.

✔ Proprietary UV Separation Technology
Uses a unique technology to separate ultraviolet (UV) rays from sunlight and flames, allowing outdoor use without false alarms caused by sunlight.

✔ High-Sensitivity & Fast Flame Detection Using UV Technology
Detects a small flame (about 2 cm high, like a lighter flame) from 5 m away.
Detects a 1 m-high flame from up to 50 m away.
Fastest detection time: 0.5 seconds.

✔ Suitable for Harsh Environments
Equipped with vibration resistance, heat resistance, dustproof, and fully waterproof capabilities, making it suitable for various extreme conditions.

✔ Built-in Reverse Polarity Protection Circuit
Ensures the sensor operates correctly even if the power polarity is reversed.

✔ Simple Wiring & Signal Output
Operates by simply connecting two power wires.
Supports both wired (open-collector) and wireless output.
To use wireless output, a wireless display unit (SKH086RDM) is required.
※ SKH086M and SKH086RDM are pre-paired before shipment.
