Frequently asked
Can these signal lamps be used with 110VAC control panels?
No, the series is engineered specifically for 24VDC operation to match modern PLC standards.
What is the expected service life of the LED elements?
The sealed optical design and efficient thermal management typically deliver over 50,000 hours of continuous use.
Are replacement lenses available for damaged units?
The dome is structurally integrated with the housing, so full unit replacement is recommended for optimal IP65 sealing.
How do I verify NPN versus PNP wiring compatibility?
Check your controller output type; the internal circuitry automatically adapts to both sourcing and sinking configurations.
