bold types = preferential sizes, available from stock Subject to modification without prior notice o M is the admissible load 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, NO (normally open); 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. SITEMA GmbH & Co. KG . G.-Braun-StraUe 13 . D-76187 Karlsruhe . The proximity switches are not included in the standard scope of delivery but are available as accessories. KRP 40, KRP 56 and KRP 100: The holders for proximity switches are arranged in reverse (H1 > H2). 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 is primed black, the front sides are treated with corrosion protection wax.
