Overview
The NSL-32SR3 is a photocell output optocoupler manufactured by Advanced Photonix. It features an LED input optically coupled to a photocell output, providing electrical isolation with a rated insulation voltage of 2000 VRMS. The device operates within a temperature range of -40°C to +75°C and supports a maximum forward current of 20 mA. Key timing parameters include a rise time of 5 ms and a fall time of 10 ms. The component has a power dissipation rating of 50 mW and utilizes axial leaded packaging.
Feature Summary
- Optical coupling between an infrared LED input and a cadmium sulfide photocell output for galvanic isolation
- High insulation voltage capability of 2000 VRMS ensuring safe signal transmission across isolated circuits
- Axial leaded package design suitable for through-hole mounting applications
Applications
- Zero-crossing detection circuits
- Light sensing interfaces requiring analog-like response
- Isolated control systems for lighting or motor drives
Procurement Notes
Verify the specific suffix 'R3' against the manufacturer's latest datasheet to confirm packaging and tape-and-reel specifications. Ensure compatibility with the required operating temperature range of -40°C to +75°C for your application environment. Confirm that the 2000 VRMS isolation rating meets safety standards for your system design.
Selection Notes
Select this component when a resistive output characteristic is preferred over transistor or photodiode outputs. The slow switching speed makes it unsuitable for high-frequency digital communication but ideal for AC line sensing. Verify that the 50 mW power dissipation limit is sufficient for the intended drive conditions.
Part Context
This part belongs to the Special Purpose isolators category from Advanced Photonix. It is distinct from standard logic-output optocouplers due to its continuous resistance-based output rather than discrete switching states. The product line focuses on specialized isolation needs where light-dependent resistance behavior is advantageous.
Replacement Considerations
Direct substitutes must match the photocell output type and axial leaded form factor. Verify equivalent insulation voltage and operating temperature ranges. Cross-reference with other Advanced Photonix photocell optocouplers if pinout compatibility is critical.
