Access Gate

By publishing the EN 17352, it has been defined standards for requirements and test methods for power-operated access control devices for the very first time. This includes i.e. turnstiles, swing lanes and retractable lanes. Thus, manufacturers of such products are obliged to take into account further safety requirements when designing new solutions. Dunkermotoren can contribute to these requirements with different approaches:

Low-energy mode compatible

Dunkermotoren's product portfolio is based on a proven modular concept. This enables the configuration of a drive whose low inertia can help to ensure the cirital kinetic energy not to exceed, which relieves the overall system. Dunkermotoren can assist in the calculation of the kinetic energy. Safely switched torque-off if critical speed is exceeded.

Fire alarm

When using appropriate control electronics from Dunkermotoren, the drive can be set torque-free via appropriate functional safety. Break-out function: Reversible gearboxes allow manual opening for escape and rescue routes.

Limitation of forces

In addition to gearbox and motor solutions, Dunkermotoren also offers integrated or external control electronics certified in according to EN ISO 13849-1 for Performance Level d (PL d) / Category 3. The control electronics are able to safely switch off torque.
» Force limitation compatible, full hit-detection coming soon
» Hit-detection, shutdown when impact detected
» Safe torque shutdown certified according to EN13849-1
