ESD Protection and Strain Relief Cables
Pin Codes: B and H
Pin Codes: A and E
SR9 Cables are
These strain relief and ESD protection products offer a convenient means of connecting a Ø5.6 mm or Ø9 mm laser diode to many of Thorlabs' laser diode controllers. Each model comes with a laser socket mounted to a small printed circuit board (PCB). The PCB contains a Schottky diode to clamp any reverse voltages that might appear across the laser diode, as well as a Zener diode to shunt any excessive voltages or ESD away from the diode.
Each model corresponds to one or more of the standard Pin Styles for laser diodes (see the diagram below) and is compatible with our Laser Diode Collimation and Focusing Tubes, Ø1/2" Post Mounts, and Cage Plate Mounts. SR9 models are designed for laser diodes with forward voltages up to 3.3 V, while SR9H models are designed for laser diodes with forward voltages up to 7.5 V. Each strain relief is available with or without a DB9 connector. Models with item #'s that end in -DB9 are pin compatible with many of our Laser Diode Controllers (see the strain relief cable and controller pin diagrams to determine compatibility), as well as with the MLDEVAL Evaluation Board for our OEM laser diode controllers. To connect fiber-pigtailed TO can laser diodes to a breadboard or Ø1/2" post, see our L-bracket Passive Fiber-Pigtailed Laser Diode Mount.
Note: These cables are not designed to provide any temperature regulation. More information on temperature regulating a laser diode is provided in the Laser Diode Tutorial.
