The NSL-32SR2S is a special purpose optocoupler manufactured by Advanced Photonix, featuring a photocell output. It consists of an LED optically coupled to a CdS photocell within a single channel configuration. The device utilizes a free-hanging mounting type and provides passive resistance output characteristics.
Verify the specific suffix 'S' against the manufacturer's current datasheet to confirm pinout and packaging variations. Ensure the application environment remains below +75°C to maintain component reliability and prevent degradation of the CdS photocell properties during operation.
Select this component when low distortion and minimal LED drive current are critical requirements. The passive resistance output makes it suitable for applications requiring high isolation with simple interface circuits. Consider thermal limits carefully as the photocell is temperature sensitive above +75°C.
This part belongs to the NSL-32 series of CdS photocell output optocouplers from Advanced Photonix. These devices are designed for specialized isolation tasks where traditional transistor outputs may introduce unacceptable distortion or complexity in the receiving circuitry.
Direct substitutes include the NSL-32SR2 and NSL-32SR3. Verify that the replacement variant matches the required package style and electrical characteristics for the specific application constraints.
