sockets

   

Sockets are supplied with mounting flanges as standard. Unflanged versions with standard or with contacts suitable for direct soldering to a pcb are also available.

The range of Electron Tubes sockets with general dimensions is shown on the pages accessed from the table below; engineering drawings of each socket type can be supplied on request.

options

  • no mounting flange
  • contacts for mounting directly to a pcb
  • non-tarnishing gold plated contacts

precautions

Sockets and caps must not come in contact with any of the following:

  • acetone
  • cyanoacrylate adhesives
  • chloroform
  • dichloromethane

Only alcohol is recommended for cleaning.

Adhesives suitable for sockets and caps are epoxy resins, polyurethanes and silicones.

When inserting or removing a photomultiplier from a socket, maintain the tube axis at right angles to the
plane of the socket as shown in the diagram below:

You must not, under any circumstances, solder directly to the pins of a hardpin photomultiplier. Flying leads may be soldered directly to a printed circuit board provided adequate heat sinking is used to protect the photomultiplier .

Soldering temperatures must not exceed 270 °C.

Electrical connections must not be made to socket contacts marked ic in the photomultiplier pin connection diagrams.
