Description
With 40 mm piston diameter and 30 mm stroke, the DFSP stops workpiece carriers at defined positions, the extended piston rod withstands impact forces up to 5540 N. Single-acting, pulling: compressed air at 1.2 to 10 bar retracts the piston rod and releases the workpiece carrier, the spring handles the return.
Benefits
- Impact force on the extended piston rod up to 5540 N, lateral force during switching up to 1108 N
- Cycle frequency up to 5 Hz, operating pressure 1.2 to 10 bar
- Piston rod in high-alloy stainless steel, CRC 2
- Position sensing via proximity switches, air connection G1/8
Applications
Typical locations are assembly lines, transfer systems and test stations where workpiece carriers are stopped reliably with a 40 mm piston. The DFSP-40-30-PS-PA can be installed in any position and operates at -10 to 80 °C.
