Gun talk - Sega Type-II IR Gun setup

Any chance there is some type of identifier or part number on those IR sensors at the tip?

Also, has anyone taken apart the Time Crisis 4 gun for PS3 that uses the IR LEDs attached to the TV?  Any similarities?

I looked when I had it apart, there are none visible. The only place where one would fit would be the back side but you'd have to de-solder it from the PCB to check and I'm not willing to disassemble a working sensor that far.

Hello, sorry this is an old thread but it's the only place on the internet where i can find something related to my problem.

I have a Sega Golden Gun and the light sensor broke in half, i've attached a picture of it.
The code is GZH200HF, i was wondering if GZH200D is compatible with my game. Would appreciate some feedback.

It looks like the part might still be good.   

 If you detach the small board, lay the board flat,  place the detached optical section back in place, and heat in a toaster oven.. you could get the soldier to re-flow,  and probably get the part to attach just fine.

 Do some research into reflow, and temperature and duration...  as too little = no reflow... and too much.. can melt plastics and or kill components.

 I do not think the optical sensor that fell off is broke in half.  I believe its actually two individual sensor chips,  based on the 4 solder ball points
on each chip.

 New non-lead based solder has a lot of problems with good smooth flow... and as such,  there is probably a 50% failure rate on all modern electronic circuit boards,  as a result.   These failures can happen immediately,  a few months,  or even years down the road.  Temperature changes,  vibrations,  can cause the already weak connections to break free.  Also, there tends to be small micro-spikes in the process... and these spikes can break off, and cause electronic shorts.

 Also, you may first want to clean the parts with rubbing alcohol, then apply some decent quality flux.  The flux greatly aids in flow and bonding.

Thanks for the info, will try reflowing, there are some computer services around and will ask around for a profesional opinion.
Meanwhile i ordered a new part from sega.
