Overview
The NSL-32 is a photocell output optocoupler manufactured by Advanced Photonix. It features an LED input optically coupled to a cadmium sulfide (CdS) photocell, providing passive resistance output. The device offers 2000 Vrms isolation voltage and operates within a temperature range of -40°C to +75°C. Key electrical parameters include a maximum forward current of 20 mA, forward voltage of 2.5 V, reverse voltage of 4 V, and power dissipation of 50 mW. Rise time is specified at 5 ms and fall time at 10 ms. The component is available in bulk packaging.
Feature Summary
- Photocell output optocoupler with passive resistance output
- High isolation voltage of 2000 Vrms
- Compact and moisture resistant package design
Applications
- AC line monitoring
- Light sensing applications
- Isolated control circuits requiring analog-like response
Procurement Notes
Verify RoHS compliance status as the specific NSL-32SR3 variant listed in distributor data indicates non-compliance. Confirm lead times and availability through authorized distributors such as Mouser or DigiKey. Ensure the correct suffix (e.g., SR3) matches the required packaging and specification requirements for your application.
Selection Notes
Select this component when high isolation voltage and passive resistance output are required. Consider the slow rise and fall times compared to transistor outputs. Verify that the forward current limits and power dissipation ratings suit the driving circuit constraints. Check temperature range compatibility for harsh environments.
Part Context
The NSL-32 belongs to the NSL series of special purpose isolators from Advanced Photonix. It is functionally similar to the NSL-32SR2 and NSL-33-007 but differs in specific electrical characteristics and packaging options. This series provides isolated optical coupling using photocell technology rather than standard phototransistor outputs.
Replacement Considerations
Public confirmed substitute part numbers are not explicitly provided in the source material. The NSL-32SR2 is listed as a related product but may have different specifications. Cross-reference with HCPL-4200 or HCPL-2602 only if functional equivalence is verified against datasheet parameters.
