Characteristics contained in this data sheet refer to divider A
unless stated otherwise.

The 9306KB meets the specification given in this data sheet.
You may order variants by adding a suffix to the type number.
You may also order options by adding a suffix to the typenumber. You may order product with specification options
by discussing your requirements with us. If your selection
option is for one-off order, then the product will be referred toas 9306KA. For a repeat order, ET Enterprises will give theproduct a two digit suffix after the letter B, for example B21.
This identifies your specific requirement.
