Weight (packed state) Calculate using the following expressions:

(2) For F3SJ-A[][][][]20/F3SJ-A[][][][]25/F3SJ-A[][][][]30, weight (g) = (protective
height) x 1.5 + α
(3) For F3SJ-A[][][][]55, weight (g) = (protective height) x 1.4 + α
The values for α are as follows:
Protected height 245 to 596 mm: = 1,100 protected height 1,660 to 2,180 mm: = 2,400
Protected height 600 to 1,130 mm: = 1,500 protected height 2,195 to 2,500 mm: = 2,600

and weigh 120 g. This weight is not included in the above formula.)

Note: 1. Vibration
             When using Curtains with a protective height of 605 mm or more, the vibration performance of the applicable
             sensor is reduced.
             Do not use these Curtains in locations that are subject to vibration.
         2. Operating range
              When using these cases, the operating range of the applicable sensor is reduced.
              Check the specifications prior to use.
         3. Mounting direction
              When using Curtains with a protective height of 605 mm or more, some slackness occurs due to the weight
              of the Curtain.
              For this reason, mount these Curtains only in the vertical direction.
Mounting direction (the cable end and terminating end can be positioned in either direction)
