Page 4: Important Information
Symbols used Warning Note 2. General description All models in the PClamp, PClamp N, ISO and E series are round-rod clamping and braking elements. All PClamp products open pneumatically and generate their clamping force via a spring accumulator. The retaining force is exerted by the friction applied by the clamping sleeve, which is pressed vertically against the contact surfaces on a round rod.
Page 5: Model Variants
A1 =0 3. Model variants The PClamp N, ISO, E components are available in different sizes. The sizes are derived from the sizes of standard ISO/VDMA cylinders. Cylinders and the PClamp N, ISO components possess identical footprints. The model variants differ in the following aspects: number of clamping modules;...
Page 6: Use
The switching times for all the controls and the response times by the PClamp N, ISO, E components must be observed, the braking distances must be calculated and checked during commissioning.
Page 7: Improper Use/Warnings
PClamp N, ISO, E cannot be used as guides or as bearings for moving machine elements. Shearing forces may result in reduced braking/retaining forces and torques, limit-switch malfunctions and/or defects.
Page 8: Warranty
Removing, dismantling or machining the PClamp by the customer without prior consent issued in writing by HEMA reduces the operating safety and renders the warranty void. The clamping sleeve's interior size has been produced to an exact value at the factory. The largest possible retention force results from the smallest radial clearance between the clamping sleeve and round piston rod.
Page 9: Transport/Storage/Intermediate Storage
The engraving can be found on the intermediate panel under the air and sensor connections on the PClamp N and ISO type clamps; the engraving can be found on the front next to the air connection on E type clamps.
Page 10: Installed State (Example)
Important! Connections with high flow resistances (long, thin, tight radii, bends) may affect response times. High speed or fast ventilation valves can considerably reduce the response times of the PClamp! Never fit two or more PClamps above each other; HEMA supplies special solutions for such requirements. 12. Installed state (sample)

Operating instructions 13. Installing the PClampp Carry out installation in the following steps: Open the PClamp with compressed air Position Venting and alignment Screw tight Optional, fitting and adjusting inductive limit switches. The individual steps in detail: Screw in an appropriate pneumatic connection: Size 63 Size 80 G1/8...
Page 12 PClamp is closed and thus centred Do not exceed the recommended tightening torque (see Page 10), use bolt adhesive. Check the screw connections in regard to the occurring loads. HEMA assumes no warranty for this. Apply nominal pressure to the PClamp and check for ease of movement. If necessary,...
Page 13 Operating instructions Finally, install and set the limit switches for condition monitoring. To this end, change the control to the different respective switching statuses and choose the screw-in depth such that the one monitoring diode lights up in sequence with the other. The switch close to the air connection must be activated in the clamped condition, the switch furthest away from the air connection must activated when open.
Page 14 16. CE marking In the delivered state, the PClamp N, ISO, E clamping elements fulfil the requirements under the Machinery Directive 2006/42/EC and are marked with the CE symbol.
