Lapp Connecto Oy – Subcontracting and System Integration
Lapp Connecto’s roots trace back to 1988, when Suomen Johdinvalmiste Oy was established in Hyvinkää. From the start, we were a determined company set on bringing a fresh approach to the cable and harness markets. Over these decades, we have grown to become part of the international LAPP Group, but we haven’t forgotten our roots or our original passion: delivering solutions that support our clients’ growth and sustainability. Every step we take has been fueled by innovation and continuous improvement, making us a reliable partner across industries – and that’s how we intend to remain.
