Description
With 0.4 J energy absorption per stroke and 4500 J per hour, the DYSS in size 3 catches moving masses at the end of stroke. No adjustment is needed on the DYSS in size 3 because the cushioning adapts itself to the load.
Benefits
- Energy absorption up to 0.4 J per stroke and 4500 J per hour
- Impact speed up to 1 m/s, mass range up to 1 kg
- Stop force up to 80 N, residual energy max. 0.004 J
- Return time 0.2 s, return force 0.4 N
- Suitable for battery production with reduced Cu/Zn/Ni content (F1a), CRC 2
Applications
The absorber sits at end stops of linear and swivel motions and protects both the mechanism and the workpiece. The DYSS-G8-3-4-Y1F-F1A-G2 is rated for -10 to 80 °C ambient temperature, any mounting position.
