Continuous 24/7 monitoring of electrical panels to detect abnormalities at any time.
Early detection of sparks through ultraviolet (UV) reflection sensing, allowing preventive action before fire outbreaks.
Specialized design for electrical cabinets and control cabinets, enabling quick identification of high-risk conditions and reducing asset damage.

✔ Easy Installation
Can be directly mounted on DIN rails, which are widely used in power distribution and control panels.
✔ Compact & Lightweight
Small body with dimensions W35mm × H90mm × D58mm, integrating high performance.
*Lightweight at only 80g.
✔ Relay Output with C Contact
Equipped with convenient relay contact output.
Can be directly connected to equipment or I/O ports of PLCs for automation control.
✔ Wide Power Supply Range
Supports DC 12V–30V.
When used with the SKH089PW sensor output mixer with power supply, it can operate within AC 100V–220V.
✔ Detection Timer Function
Adjustable detection timer to match the operating environment.
Selectable range: 0.5s, 1s to 31s (adjustable in 1-second increments).
DIP switch on the back allows easy timer configuration changes.
※ After changing the setting, the power must be restarted for the new settings to take effect.
