Paramètres du produit

Optocouplers (Photocell (CdS) Output)

The CdS photocell output optocouplers optically couple an LED to a CdS Light Dependent Resistor (LDR). The LDR resistance increases when the LED current is OFF and decreases when LED current is ON. The device showcases a large dynamic range with a response time that efficiently mimics the human eye's sensitivity to light changes. Engineered with High, Medium, and Low dark resistances, the optocouplers are available with diverse resistance values to suit various applications. The photocells are encased in an opticallyisolated structures.

NSL-26 Optocoupleur (Type photorésistance CdS associée à une LED)

Type No.: NSL-26 

This optocoupler consists of an LED input optically coupled to a TO-5 Hermetic photocell. The photocell resistance is high when the LED current is "off" and low resistance when the LED current is "on".

■Typical Applications:

  • Industrial

■Features

  • Compact, moisture resistant package
  • Low LED current
  • Passive resistance output
  • Hermetic Photocell

■General Care and Handling Instructions

Handling and Storage

• Handle Optocouplers and LEDs gently to prevent damage.

• Avoid exposing the devices to temperatures exceeding the storage temperature rating of the device.

• Maintain a non-condensing environment for optimum performance and lifetime.

Cleaning

• For plastic molded devices, cleaning with a 50/50 mixture of Methanol and isopropyl alcohol is recommended. Cleaning in an ultrasonic bath is generally not recommended.

Special Considerations

• Avoid exposing plastic molded devices or epoxy glob topdevices to harsh chemicals like THINNERS, ACETONE, andTRICHLOROETHYLENE.
