We are based in Scotland and specialise in the design, development and manufacture of ATEX/IECEx Opto Couplers/Opto Isolators and High Voltage Couplers. BOT are the UK’s only manufacturer of ATEX/IECEx certified Opto Couplers and as such we supply worldwide.

The difficult economic times we are experiencing have resulted in some major changes to our standard product range. Whilst we retain the necessary skills to design & develop the full spectrum of visible and Infra Red products and assemblies, reducing volumes no longer justify our continuing to offer the full range and many products have been removed from our site.

All customers affected by these changes have been contacted and offered all time buys. Many custom specials will continue to be manufactured. If you have a problem please contact us as soon as possible.
