^1 Mixed expansion at a 20 mm or 40 mm pitch is possible. The number of units that can be connected in a mixed expansion is 8 units or less. ^2 When the PJ-F41 / F42 has been added to the PJ-F20 / F21, the optical axis pitch of added unit is 40 mm, and 20 mm when the PJ-F21 / F22 has been added to the PJ-F40 / F41. ^3 When performing mixed expansion at a 20 mm or 40 mm pitch, there is no limit on the number of axes if the number of connected units is 8 or less. ^4 With mixed expansion, this becomes 140 mm [when the PJ-F20 is used] or 120 mm [when the PJ-F40 is used] +20 mm x (the number of 20 mm pitch extension optical axes) +40 mm x (the number of 40 mm pitch extension optical axes).
