Advanced Photonix NSL-32SR2 Optocoupler, Photocell/LDR Output, Axial 4-Pin, 25m

The Advanced Photonix NSL-32SR2 is a resistive output optocoupler designed to provide reliable electrical isolation and signal transmission. It consists of an input LED that is optically coupled to a light-dependent resistor (LDR) or photocell. When the LED current is OFF, the photocell exhibits a high resistance, and when the LED current is ON, the resistance drops to a low value. This passive, resistance-based output makes it a versatile component for various control and interface applications.

This device is housed in a compact, axial-lead package that is moisture-resistant, ensuring stable performance in diverse environmental conditions. It features the lowest ON resistance in its class, enabling efficient signal transfer. A key advantage is its very low LED current requirement, which helps to minimise power consumption in your circuit design.

The NSL-32SR2 produces a low-distortion output, making it suitable for applications where signal integrity is paramount. Its robust 2kV isolation voltage provides a high degree of safety and protection against voltage spikes, separating input and output circuits effectively. With its axial lead format, it is easy to mount on printed circuit boards (PCBs) for through-hole assembly.
