Note 2: When using shock absorber type, refer to K in the stopper dimensions table on page 726. Note 3: Refer to stopper dimensions on page 726 for port positions. Note 4: When no stopper, port position of standard type are as following Fig. and. Note 5: The stopper for adjustable stroke and shock absorber stopper combination is available as a custom order. Note 6: Selectable only when using a stopper. Note 7: Refer to the selection table on Page 70 for combinations of options. Note 8: For 6 to 8 cylinders with 0mm stroke or 2 to 25 cylinders with 20mm stroke or less, custom order is applied because A**, A2**, A5** and A6** can not be adjusted by a standard stopper. Note : For 6 to 8 and 30mm stroke or less cylinder with S*** or A*** switch, when two switches will be installed, select F*H type switch. <Example of model number> LCG-2-40-F2H-R-ADT Model: Linear slide cylinder double acting single rod type LCG A Bore size : 2 B Stroke length : 40 mm C Switch model no. : Proximity, 2-wire Axial lead wire D Switch quantity : One on rod end E Other options : Shock absorber type Stopper position Side surface and bottom side ports presence Material and alloy steel (nitriding) 708 S5 LCG 2 40 F2H* R ADT D Switch quantity C Switch model no.
