Hi, I've purchased an SR9B-DB9 and it is not compatible with the LPS-830-FC, which uses a Pin code "C". Would it be ok to rewire the DB9 connector for the C code type? Thank you.

jpolaris (posted 2024-02-22 04:31:24.0)

Thank you for contacting Thorlabs. Since SR9B-DB9 and SR9C-DB9 use the same voltage protection elements, it might be possible to rewire the DB9 connector to the correct PD polarity, but there is a high risk of damaging the cable and doing so would void any warranty. The protection electronics are not designed to be easily modified. I have reached out to you directly to discuss possible alternative solutions.

Hello, we have just ordered the cable selected above (SR9A-DB9). Could you send us a matching CAD model of the side with the strain relief? When assembled is perfectly fine, it's all about the outer dimensions. That would be great! Thank you very much and best regards, Patrick Kühl

Thanks for reaching out to Thorlabs. You can view the CAD file for the SR9A-DB9 by clicking on the red document icon next to the item above. Please let us know if there are any dimensions not listed which impact your application, and we can investigate further.

Hi, Can I have a circuit diagram of SR9F? I am considering using SR9F to mount a photo diode instead of LD. The reverse bias to PD may interfere with the Schottky diode. Please provide me an advice. Thanks

asundararaj (posted 2020-01-22 10:20:49.0)

Thank you for contacting Thorlabs. The SR9F or other strain relief cables can be used to mount photodiodes, you would have to connect the Anode and Cathode of the photodiode on to the PDA and PDK on the Strain relief cable. The Schottky diode is across the LDA and LDK pins only and should have no effect.

Warren Massey (posted 2019-10-31 09:28:54.99)

For the 3.3 V Zener diode and the Schottky diode used on the SR9F board, can you tell me what their part numbers are? Or if that is not allowed will you at least tell me what each of their respective datasheets list as their maximum-allowed operating and storage temperatures.

asundararaj (posted 2019-11-01 11:13:35.0)

Thank you for contacting Thorlabs. The storage and operating temperature range of the component Zener diode is -65 to +150 °C and that for the component Schottky diode is -55 to +150 °C. Please note that this is not the storage and operating temperature of the strain relief cables.

Hello, I seem to have broken my laser diode cable. I ordered a new one but the the ETA is July 23rd. :-( Is it possible to get the circuit diagram for the SR9HA-DB9 so I can troubleshoot and maybe repair it myself? BR Marcelo

YLohia (posted 2019-07-12 09:54:20.0)

Hello Marcelo, thank you for contacting Thorlabs. I have reached out to you directly to discuss the possibility of obtaining this.

It seems like there is an error in the documentation (the engineering drawings/schematics) for a substantial number of the -DB9 variants of these cables. The pin-out table in the top left lists the wrong colour wires for the laser anode and laser cathode. On the SR9HB-DB9 it reads "White - Photodiode Cathode (PDK) Laser Diode Anode (LDA" and "Green - Laser Diode Cathode (LDK)". These should be the other way around, when compared to the diode pins and physically following the connections through on the circuit board.

nbayconich (posted 2017-11-20 09:42:10.0)

Thank you for you feedback. We are currently correcting the pin-outs in our strain relief cable schematics. Thank you for bringing this to our attention.

whath90 (posted 2016-11-15 14:16:05.94)

Could you let me know the maximum allowable current of SR9B-DB9 series or what the AWG number of wire is?

tfrisch (posted 2016-11-28 02:50:56.0)

Hello, thank you for contacting Thorlabs. The current will most often be limited by the diode rather than mount. The socket and AWG of the wires in the mount would be able to handle at least 1A, but since there is no temperature control for the diode in these mounts, the thermal load of a diode with such high drive current would prohibit it from being used with these cables for its own stability and temperature requirements. I have contacted you directly with more information.

Can you customize the series for PL450B?

besembeson (posted 2016-02-04 10:40:24.0)

Response from Bweh at Thorlabs USA: We have the SR9HF or the SR9HF-DB9 with 7.5V forward voltage that should be suitable for the PL450B.

Our lab already ordered MMF coupler FCMH2-FCL. and I'm thinkging of buying LP520-MF100 to connect to this coupler use LP520-MF100 as a laser source. To use this LP520-MF100 can I use (1)SR9HF-DB9 and (2) PTLB1 ?

besembeson (posted 2015-09-24 06:35:51.0)

Response from Bweh at Thorlabs USA: Yes that combination should work, if the laser diode will not be run continuously for long hours, in which case a temperature controlled mount such as the LDM9LP will be recommended. You will also need a laser current controller such as the LDC205C.

In response to my own inquiry, this can help other customers: I have just found out that the external thread on the SR9x series of cable fits the following adapter: S05LEDM and S1LEDM. Thorlabs, could you then offer the S05LEDM and S1LEDM without the LED mounting accessories (for a cheaper price), as part of your standard line of adapters?

ludoangot (posted 2015-06-03 15:07:05.723)

Could you offer an adapter to mount the SR9 cable to SM1 tubes (internal = thread of the SR9 and external SM1 threads)? This would allow a great flexibility in building custom optical designs integrating the advantages of that cable (ESD protection, strain relief).

jlow (posted 2015-08-25 11:49:23.0)

Response from Jeremy at Thorlabs: We offer this adapter at http://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=366. For Ø9mm LD, the part number is S1PLDM9. For Ø5.6mm LD, the part number is S1PLM56.

Liebes Thorlabs Team, für Beleuchtungszwecke verwenden wir eine LED mit der Halterung SM05 LED Mount for TO-18, 46... Um Lötarbeit zu sparen würden wir diese gerne mit dem SR9A Kabel kombinieren. Damit man das Kabel aber sicher auf dem SM05 LED-Mount aufschauben kann, müßte diese einige mm länger sein. Gibt es ein entsprechendes Bauteil, bzw. Adapter? Oder ein Adapter um ein simples T 1-3/4 Package bzw. TO-46 Package in einer LT110P-B Collimation Tube zu verwenden? Vielen Dank, mit freundlichen Grüßen Lin Robert Borowski

Response from Jeremy at Thorlabs: Thank you for contacting Thorlabs. We will contact you directly on putting together the SR9A cable with the S05LEDM for your application.
