ROBA-stop-S Electromagnetic Safety Brake

•Protection IP 67

•Fully corrosion protected

•Highest permissible friction work

•Tacho attachment possible

ROBA-stop®-S Brakes have two functions. During standard operation they work as holding brakes. When the drives have been switched off the brakes hold the equipment safely in position. During critical operational situations, e.g. with emergency-off or power failure, ROBA-stop®-S Brakes are designed to absorb peak loads with high friction work. These brakes are designed for vertical and horizontal operations.

Dust and waterproof

Completely enclosed design of the brake corresponds to IP 67 protection.

Permanent protection against corrosion

IP 67 protection, a high-quality primary coat of the brake body, chrome or nickel coated interior parts or a rustproof steel manufacturing assure sustainable protection against corrosion.

Easy handling

Compact construction and small outer diameters provide an easy handling of the brakes.

Inspection without standstill of equipment

One hole allows fast inspection of the air gap without dismantling the brake or stoppage of the equipment.

Minimum maintenance expenditure

In case the friction linings are worn only the air gap must be reset or the rotor with the friction linings must be exchanged respectively.

Minimum operating expenses

High working reliability and less maintenance expenditure reduce the operating expenses of the brake to a minimum.

Rectifier

A rectifier integrated in the terminal box allows a brake connection to AC-supply. The magnetic coil is designed as DC-coil.

Wear control

An additional micro switch can be installed into the ROBA-stop®-S Brake which monitors the wear of the friction linings.

Brake housing and integral terminal box

The one-piece cast iron housing with integrated terminal box is extremely robust and, therefore, protected against mechanical damages.

Anti-condensation heating

The heater avoids condensation water inside the brake. This usage is especially recommended with temperatures under zero degree Celsius or in case of high air humidity.

Braking torque

By changing the number of springs the brake torque can be adapted to customer's requirements.

Optimum protection for electrical equipment

The electrical supply and the micro switch of the inspection and monitor functions are completely protected inside of the cast terminal box.

Release monitoring

The ROBA-stop®-S Brake is fitted with a micro switch for release monitoring. The micro switch supplies a signal if the brake is opened.

Tacho attachment

The brake body has a possibility for a tacho attachment. If no tacho is used, the coil carrier is closed by a cover.

Emergency hand release

The ROBA-stop®-S Brake is fitted with an emergency hand release. The brake can be released mechanically via two screws. (Lever type hand release on request)

Condensation water inspection

A regular inspection is possible via a drain plug.

Motors with self-ventilation

In order to assemble the ROBA-stop®-S Brake onto motors with through-going shafts at the Bbearing side, the closed standard cover at the brake back side is exchanged against the open cover with integrated radial shaft seal ring.
