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 4 bar. In case a spring base is installed, the required pressure for releasing without lifting is 6 bar, see “TechnicalData Sheet TI-A20”. The admissible operating pressure is 10 bar. © Pneumatic operating volume Q Proximity switch holders are provided for standard inductive proximity switches (M12 x 1, nominal switching distance 2 mm, flush mountable, NOC; except KRP 25 and KRP 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. KRP 25 to KRP 80: 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. 0 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 with clean atmosphere (e.g. a clean pressureless container). 0 The surface of the housing parts consists of stainless steel (for KRP 25, KRP 80) or of aluminum, anodized (for KRP 40, KRP 56).
