Sigma series Modular Mounter, Rotary head design for a “1-head solution” with both high speed and versatility

The Σ-G5S II retains all the features of its predecessor, including the high-speed high-accuracy rotary direct-drive head, the overdrive motion for highly efficient production by picking up components from either the front or rear feeder on the machine, and the Super Loading (SL) feeder that facilitates splicing-less*1 component supply. It also gains new head designs, an improved PCB feeding sequence, an enlarged internal buffer size for feeding larger PCBs and more to improve productivity. Additionally, its mounting speed of 90,000 CPH*2 (under optimum conditions)*3 represents an improvement of approximately 20% compared to the Σ-G5S.

Techical info

The Σ-G5S II premium modular mounter is based on the Σ-G5S, which has been highly regarded for its “1-head solution” using a rotary head that achieves both high speed and versatility without the need for head replacement to cater to a wide variety of components. The Σ-G5S II adopts new head designs and other features to further improve productivity and supports super-small 0201 (0.25 × 0.125 mm) size components.


Quality has also been improved by extending the detection range of components held by the mounter to immediately before placement. In addition, reliability has been further enhanced due to better balance for the beam motors to bolster stability, lower internal temperature by improving cooling performance, extending the service life of important components like the high-speed multi-purpose head and more
