Overview
The NSL-32SR2 is a special purpose optocoupler manufactured by Advanced Photonix. It consists of an infrared LED input optically coupled to a Cadmium Sulfide (CdS) photocell output. The device provides electrical isolation between the input and output circuits. Key specifications include an operating temperature range of -40°C to +75°C. The component features an OFF-resistance of 1MΩ when the LED current is off, ensuring high isolation in the non-conducting state.
Feature Summary
- Optical coupling between an LED input and a CdS photocell output for signal transmission
- High OFF-resistance characteristic providing effective electrical isolation
- Temperature sensitive operation suitable for specific environmental conditions
Applications
- AC line monitoring systems
- Power supply control circuits
- Special purpose isolator applications requiring resistive output
Procurement Notes
Verify the manufacturer designation as Advanced Photonix or its successor entity Luna Optoelectronics. Confirm the package type matches the required footprint. Ensure the operating temperature range of -40°C to +75°C aligns with the system environment. Check for any specific handling requirements due to the CdS material composition.
Selection Notes
Select this component when a resistive output interface is required rather than a transistor or diode output. Consider the temperature sensitivity of the CdS photocell for the intended application environment. Verify that the 1MΩ OFF-resistance meets the isolation requirements of the circuit design.
Part Context
The NSL-32SR2 belongs to the NSL-32 series of optocouplers from Advanced Photonix. This series includes variants such as the NSL-32 and NSL-32SR3. These devices are categorized under special purpose isolators and utilize photoresistive technology for signal coupling.
