bold types = preferential sizes, available from stock Subject to modification without prior notice O M is the admissible force the mass to be secured exerts on the Safety Catcher. The holding (braking) force for dry or hydraulic-oil wetted rods is not less than 2 x M but will not exceed 3.5 x M. 0 The necessary pressure to keep the clamping released is 40 bar. In case a spring base is installed, the required pressure for releasing without lifting is 60 bar, see “Technical Data Sheet TI-A20”. The admissible operating pressure is 250 bar. 0 As supplied, pressure port LL is plugged by a plug screw. It may be used alternatively to pressure port L and is useful for filling / airbleeding. We recommend to install an auto-bleeder at port LL (or L) as described in “Technical Information TI-Z10”. O Hydraulic operating volume 0 Proximity switch holders are provided for standard inductive proximity switches (M12 x 1, nominal switching distance 2 mm, flush mountable, NOC; except KR 25 and KR 28: M8 x 1 with a nominal switching distance of 1.5 mm). The dimension T3 indicates how deep the proximity switch immerses in the Safety Catcher measured from the holder's top. For easier service, the proximity switch holders have a depth stop and are pre-adjusted when delivered from the factory. The switches only need to be inserted to the stop and then clamped. The proximity switches are not included in the standard scope of delivery but are available as accessories. o Internal volume changes during switching are compensated at port T. It is plugged with an air filter which, in a dry and clean factory environment, offers sufficient protection against dust etc. If, however, moisture or aggressive media are present, a pressureless hose instead of the filter must be installed to connect the Safety Catcher KR with clean atmosphere (e.g. a clean pressureless container).
