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 “Technical Data Sheet TI-A21”. 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/T 25: M8 x 1 with a nominal switching distance of 1.5 mm). The dimension T1 indicates how deep the proximity switch immerses in the Safety Catcher KRP/T measured from the holder's top. For easier service, the proximity switch holders have a depth stop. If you order a suitable SITEMA flange to the Safety Catcher, the proximity switch holders will be mounted and pre-adjusted to the right depth. The switches only need to be inserted to the stop and then clamped. If the Safety Catcher is delivered without flange, the holders will not be mounted and pre-adjusted because the flange needs to be mounted beforehand. After mounting the flange, the holders have to be mounted and readjusted to the right depth. 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 KRP/T with clean atmosphere (e.g. a clean pressureless container). o The surface of the housing parts consists of stainless steel (for KRP/T 25, KRP/T 80) or of aluminum, anodized (for KRP/T 40, KRP/ T 56).
