Nekos SKY 650
After the first decade Nekos also made modifications and developments in their family of linear rack actuators.

Nekos SKY 650 improves its performance, reliability and range of applications:
▪ The push and pull force of 600 N controlled and managed by a microprocessor guarantees long lasting reliability.
▪ Versatile and modulable without expensive parts and accessories, the new electronics and latest-generation mechanical setup contribute to making this actuator even more unique in its kind.

▪ Light domes, skylights, sun blinds or a series of awning windows are the most common applications.
▪ The rack strokes ranging from 180 to 1000 mm allow for a broad range of applications.
▪ The actuator is fastened by means of a clamp system along the entire length of the rod with oscillating support that allows the actuator to follow the opening radius of the window.
