SUMMARY

The discussion centers on the challenge of finding smaller SHV connectors for Hamamatsu R6233HA photomultiplier tubes (PMTs). The user, Herbert Graaves, has encountered difficulties sourcing connectors with a .110 inch diameter, as most available options are larger, around 0.56 inches. Despite searching through suppliers like Newark and Digi-Key, no suitable connectors have been identified. The Hamamatsu website also lacks relevant information regarding compatible SHV connectors.

PREREQUISITES
  • Understanding of photomultiplier tube (PMT) specifications
  • Familiarity with SHV connector types and sizes
  • Knowledge of high voltage wiring standards
  • Experience with electronic component sourcing
NEXT STEPS
  • Research alternative suppliers for SHV connectors, focusing on specialized electronic component retailers
  • Investigate custom connector manufacturing options for specific diameter requirements
  • Explore forums or communities dedicated to photonics for shared experiences and solutions
  • Contact Hamamatsu directly for recommendations on compatible connectors
USEFUL FOR

Engineers, technicians, and hobbyists working with photomultiplier tubes, particularly those seeking specific high voltage connectors for Hamamatsu models.

I am currently working on a project in which photomultipliers are used. Specifically, they are Hamamatsu R6233HA models. In order to test these tubes, I have to connect the wires to a high voltage source. The problem is the wires are .110 inch in diameter and are not connected at the ends, so I an trying to locate an SHV connector for the high voltage wire. However, all I can seem to find is larger SHV connectors such as those 0.56 in in diameter. I have searched Newark, Digi-Key, and other websites for smaller SHV connectors, but to no avail. Furthermore, the Hamamatsu website does not provide any helpful information in terms of what SHV connectors to use, and where to find them.

Has anyone had a similar problem before, especially if you have used the Hamamatsu PMTs in the past, and if so, where I could find smaller SHV connectors? I do not want to resort to using other high voltage connectors (i.e. Limo)if I can help it.

Thanks,

Herbert Graaves
