ESD Protection and Strain Relief
|SR9A||A and E||3.3 V|
|SR9B||B and H|
|SR9C||C and H|
|SR9HA||A and E||7.5 V|
|SR9HB||B and H|
Note: A -DB9 at the end of the part number indicates a DB9 connector. Otherwise, the end of the cable is terminated with bare wires.
The SR9 Series of strain relief and ESD protection products offer a convenient and safe means of connecting your Ø5.6 mm or Ø9 mm laser diode to our line of Laser Diode Controllers. Each model comes with a laser socket mounted to a small Printed Circuit Board. 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 LT Series Collimation Tubes and Laser Diode Cage Plate Mounts. SR9 models are designed for laser diodes with forward voltages of 3.3 V, while SR9H models are designed for laser diodes with a maximum forward voltage of 7.5 V. Each strain relief is available with or without a DB9 connector. All -DB9 models are pin compatible with our Laser Diode Controllers.
