Manufacturer notice
Original manufacturer quality.
We are the original manufacturer of the KTR IR industrial controller series and supplied it to our long-standing distribution partner KTR. KTR has discontinued the distribution of this product line through its own channels. We have been manufacturing these products in unchanged form for several decades. The only difference to the version previously distributed by KTR: the product now bears our own company logo and manufacturer’s nameplate. Design and technical specifications are completely identical.
