We were incorporated in April 1989, specialising in industrial and commercial Optocouplers and isolators, optoswitches and sensors, and discrete infrared Optoelectronic components.

Compared to some names in the industry, our name is not a household name, but we are emerging as one of the industry's more familiar names, synonymous with reliability, on-time delivery, and customer service.

Dedication, solely to the support of our worldwide customer base, as only a specialised supplier can be, we have generated customer confidence that their Opto requirements will be supported both in the short and long term. This is especially important as many of the major names have or are retreating from commodity product lines in favour of more high tech endeavours.


Product Offering:

The Product Line includes all of the major commercial Opto-Couplers/Isolators with the highest priority being the pursuit of excellent product quality and reliability plus the maintenance of approvals to all safety standards as defined by UL, CSA, BSI, VDE, Nemko, EN60950, and CEC (as the criteria is determined).

A major strength is our ability and willingness to perform special parametric selections to meet specific application requirements without imposing quantity restrictions. In addition, our ability to furnish standard and custom Optosensors/switches, incorporating special packaging and custom assemblies, including cables, connectors, and other components, provide a true plug-in module solution.

Although the data on our website provides a comprehensive look at our product line, if your product of choice is not listed, please contact our Customer Service department; in most cases, we have the capability to supply you with the exact device needed for your application.
