Antec SKH047MF Flame Detection Sensor

Manufacturer: Antec Co. Ltd.
Model: SKH047MF

Features

FM certification ensures product safety and performance, awarded to products meeting specific standards. The “FM Approved” mark signifies high reliability.
We are the first to receive FM certification for a non-explosion-proof ultraviolet flame sensor (as of October 2024), confirming superior quality and safety.
Ultraviolet Ray Separation: Minimizes false alarms by separating sunlight and flame rays.
Fast Flame Detection: Detects a 50m flame in 4 seconds.
Smallest UV Sensor: The world’s smallest ultraviolet flame sensor.
Power Lamp: Blue LED for power; turns red when flame is detected.
Voltage Output: Indicates flame detection and sensor status.
Detection Timer: Adjustable from 0.5 to 31 seconds to prevent false alarms. (FM Certification applies only to the 4-second setting)
