RELIABLE ANALOG LIGHT SENSING LDRS

LASER COMPONENTS offers reliable analog light sensing LDRs for high stability and precision sensing.

All alternatives

Power
Maximum Operating Voltage	Up to 250 V DC (varies by model)
Power Dissipation	Typically 100 mW continuous (depending on ambient temperature and packaging)
Environment and package
Temperature Range	-25 °C to +75 °C for plastic versions; wider for TO-can types
Other
Dark Resistance	Typically 0.5 MΩ to >10 MΩ (measured after 10–15 s in darkness)
Light Resistance	Ranges from ~300 Ω to 20 kΩ at 10 lux, depending on model
NSL photoresistors are available in two configurations	a hermetically sealed TO-can package for high-reliability environments and a two-pin plastic-coated ceramic header for cost-sensitive or compact applications. Both versions provide excellent durability, moisture resistance, and stable electrical characteristics over time.
Packaging Options	TO-5/TO-8 hermetically sealed metal can or two-pin plastic-coated ceramic header
Response Time	Rise and fall times between 30 ms and 100 ms (approximate)
Spectral Response	400 nm to 700 nm (peak at ~550 nm)
