About Mayser

Safety edges are sensors that protect shearing and crushing edges against pinching hazards. If the safety edge encounters an obstacle, for example if a hand gets caught in a closing door, the automatic movement is stopped immediately.

We offer Safety Edges as normally open contacts or normally closed chains, depending on the switching principle.

With the safety edge self-assembly, we give you the opportunity to manufacture your safety edges quickly and inexpensively yourself.  

We specially developed our miniature safety edges (EKS) for applications where short response times are required and only low installation heights are possible.

A classic example is their use as anti-pinch sensors on shearing and pinching edges of automatic vehicle doors and windows. However, our miniature safety edges are also ideal as anti-pinch sensors in machine construction, on electrically adjustable furniture, and on modern medical devices.

The miniature safety edges easily fit to various bending radii and angles. You can cut your anti-pinch sensor to size yourself for use in interiors.

Tactile surface sensors provide optimal area protection. 

The purpose of surface sensors is to protect people from dangerously moving units in automatic manufacturing processes. They detect people and objects in the corresponding areas of movement. When somebody steps onto a pressure-sensitive mat, the machine or plant slows down or switches off into a safe state.

Our surface sensors are available in various heights and with different material properties such as non-slip quality or resistance to various chemicals. In our "SM" customised programme, we offer you safety mats in any surface shape to match your requirements.

Safety bumpers are active collision cushions made of soft polyurethane foam with a special skin and integrated safety switch-off function. They work according to the normally closed and normally open principle.

The soft foam body protects people from injury and prevents damage to objects for short and long stopping distances. That makes our safety bumpers an ideal addition to our range of collision protection systems.

Typical applications are ensuring the safety of pinching and shearing edges in mechanical engineering, stage technology, medical technology and on large, heavy gates. Safety bumpers also provide collision protection for driverless transport systems (DTS).
Safety bumpers are available in lengths of up to 4 m and in standard or custom versions.

The capacitive system, also called non-touch detection system, acts as a predictive impact protection in public transport. It is a convenience function integrated directly on the main closing edge of Mayser finger protection profiles. 

The non-touch detection system only reacts to movements in the immediate critical area of the sensor, along the main closing edge. This distinguishes it from light curtains or scanners whose detection fields cover complete entrance areas. Another advantage is that the system is not susceptible to water. Unwanted detection is therefore not caused by rain or snowfall, nor by extraneous light or dust.

Our control units evaluate the output signals of our safety mats, safety edges and safety bumpers, then they immediately trigger the necessary safety measure.

Functional monitoring by our control units applies various principles.

A monitoring resistor integrated in the sensor measures a constant closed-circuit current in safe condition. When the sensor is actuated, the voltage drops. The control unit's safety contacts open and ensure the drive is safely switched off for 1k2, 8k2 or 22k1 final resistances.
In the case of the four-wire solution, functional monitoring takes place by feeding the signals back to the control unit.

Whichever principle is applied, the control unit stops the drive on actuation or cable interruption.
