Can you help?

[daedal]

I am currently in possession of a 635nm lasever that has got one of the circular connectors. As you can see from the photos, there is a bit of a problem... I would truly appreciate it if you have a similar unit and are willing to help.

Here is the laser head connector:


This is the connector and the corresponding laser PSU:


To get to the wires inside you can loosen the two screws on the connector, and then remove one (either one is fine). Then move them away from the wire as to make sure the wire is free and untangled. The bottom of the connector is the part that releases (be sure to get a grip on the central part of the connector as the outside will freely rotate). Pull the now loosened part back, and the end result is the wires attached to the pins. My problem (as you can see) is that some of these wires are broken... What I need is the color and corresponding pin number (see last picture for number location).

If anyone has any knowledge of where each wire connects, please let me know... See pictures below for more details...

You can fix that shitte man!!! Hurry up and fire that iron up.

The color should not change inside the driver...open it up...not a big deal to pop the head and RE it. I would open it up anyway and install a shunt until the repair was completed.

Thanx!

Well... hopefully Lasever is still around to help me with this...

I might have to open up the PSU to figure out the connections manually!

Hope it doesn't come down to that...

You think they'd be the same colors? I agree that it is good practice, and hope they did invest the time in doing that. Let's hope it's that simple...

Here's the small amount of info I have on these, but none have a green on pin2 as it looks in your pics, so I'm not sure this will be of any use


LSR-532-U-200 female connector
Pin1 = Red = LD +
Pin2 = Black = LD -
Pin3 = Yellow = TEC +
Pin4 = Brown = TEC -
Pin5 = Blue = Thermistor
Pin6 = Green = Thermistor
Pin7 = N/C


LSR-PS-I female connector
Pin1 = Red = LD +
Pin2 = Black = LD –
Pin3 = White = TEC +
Pin4 = Yellow = TEC -
Pin5 = Green = Thermistor
Pin6 = Blue = Thermistor
Pin7 = N/C


LSR-PS-III driver male connector
Pin1 = Green
Pin2 = Red
Pin3 = Yellow
Pin4 = Blue
Pin5 = White
Pin6 = Black
Pin7 = N/C

Thank you for the info... I'll check it out this evening

I got 2 replies from Lasever... First indicated they have NO documentation on what goes where. The other indicates the colors as listed above...

The wire colors might be: red for LD+, black for LD-, yellow for TEC+, brown for TEC-, blue and green for thermistor. But It is not necessary correct. You can use pins to insert into the plug to check out which holes are for LD+, LD-. Then to induct which pins on connector are for LD+ LD-. The knowledge is of electronics and laser basics.

I think I may have to open this up...

Wish me luck, and I'll let everyone know what I find...

Thanx;

Hope all gets figured out

Well... 2 days and I've been creating load simulations to try and figure this out... there is no indication that the colors really mean anything. I also don't want to damage anything...

In either case, I've resorted to an 'internal' investigation... but I'm still slightly confused...

Here's what I've got:

My best guess at this point:
Green + blue = thermistor
Red + brown = laser diode
yellow + white = TEC

You can also see the tip of the purple wire (N/C) in this picture:

After a second look, this would somewhat coincide with the colors P1t8ull posted for his LSR-PS-I

So, here I am again... looking for further input on solving this little puzzle.

Appreciating all your input;
