For encoder attachments requiring functional safety (PL e)
Suitable for foot mountings and attachments with greater offset
Play-free, torsion resistant and failsafe
Extended lifetime of encoders
Options: isolated version, Ex-proof version
Description
The corrosion-resistant HKDS metal multiple disc couplings compensate for a parallel misalignment of up to 0.5° and an axial misalignment of up to ±1.5 mm, thus extending the service life of encoders. They are safety components according to DIN EN ISO 13849-2 (PL e) with CE declaration of conformity and designed with high safety factors for fatigue resistance and fault exclusion.
In addition, HKDS safety double joint couplings can be used to implement fail-safe encoder attachments in hazardous areas. This makes them ideal for extreme operating conditions.
The double-jointed couplings are available with different hub lengths and bore diameters as well as insulated couplings for attachments with shaft current hazard.
