The LUX420 illuminance probes (lux meter lux) can aid in the control and savings in lighting installations both indoors and outdoors.

LUX420S1/S2

The LUX420S1/S2 analog sensor (lux meter lux) measures the illuminance of ambient light and converts it into a current loop signal. The 4-20 mA output signal is provided by the same power supply cable, offering easy wiring in installation.

The LUX420 light sensor is based on a Si photo-sensor, which offers sensitivity close to visible light and stable performance.

The LUX420S2 model has a wide measurement range (between 0-1000 lux and 0-100000 lux), adjustable through microswitches.

The LUX420S1 model has a wide measurement range (between 0-100 lux and 0-4000 lux), adjustable through microswitches.

The LUX420S1-20 model is adapted for measuring twilight light (20 lux, transition from night to day) as well as detecting sudden changes in brightness (storms, clouds).

Features LUX420:

• 24 Vdc power supply input provided in a 2-wire current loop
• Non-polarized output and power supply.
• 4-20 mA output that can be transmitted over long distances.
• Light sensor with maximum sensitivity to visible light
• High IP protection grade (IP64) for outdoor use
• Solid construction in stainless steel.
• Selectable measurement range via internal switch (up to 8 ranges per device)

LUX420S1-C-X

The LUX420S1-C analog sensor (lux meter lux) measures the illuminance of ambient light and transmits it via ModBus RTU RS485 bus. It allows direct communication with PLC for lighting control.

The LUX420 light sensor is based on a Si photo-sensor, which offers sensitivity close to visible light and stable performance.

High protection grade for outdoor use (IP64) and solid construction in stainless steel.

The LUX420S1-C-20 model is adapted for measuring twilight light (20 lux, transition from night to day) as well as detecting sudden changes in brightness (storms, clouds).

Features LUX420-C:

• 12 / 24 Vdc power supply input
• ModBus RTU communication with selectable parameters
• Direct reading of illuminance without conversion
• Light sensor with maximum sensitivity to visible light
• High IP protection grade (IP64) for outdoor use
• Solid construction in stainless steel.
• Selectable measurement range via internal switch (up to 8 ranges per device)
