Three sensor principles in one series: O500 offers a wide range of photoelectric sensors
The new O500 series from Baumer is starting off with three optical sensor principles at SPS/IPC/Drives. So Baumer now offers a wide range of photoelectric sensors for numerous applications.

Miniature Safety Edges

Mayser Miniature Safety Edges were specially developed for areas where only extremely short overtravel distances and minimum installation heights are possible. One classic example of their use is as Anti Pinch Sensors on pinching and shearing edges of automatically closing vehicle doors and windows. However, Mayser Miniature Safety Edges are also used as collision and Anti Pinch Sensors on electrically operated lounge furniture and modern medical treatment equipment.

Control Units

Mayser Control Units analyse the output signals of our Safety Mats, Safety Edges and Safety Bumpers and immediately trigger the necessary safety measures. The functional monitoring of Mayser evaluation units is carried out according to different principles.

In the case of 2-wire technology, a constant closed-circuit current is measured by means of a monitoring resistor integrated in the sensor. If the sensor is activated, the voltage drops. The safety contacts of the Control Unit are opened and ensure safe shut-off of the drive.

Safety Edges SL/NC according to the normally closed principle

The principle of the Mayser normally closed Safety Edges SL/NC is based on a chain made up of normally closed contact links integrated in a rubber profile. When the normally closed Safety Edge is activated, an existing contact is interrupted. The principle contrasts with the normally open Safety Edge, where a contact is closed, thus triggering a signal.

Safety Mats (contact mats)

Mayser Safety Mats are tactile sensors which offer maximum protection when safeguarding flat operating areas. Safety or Contact Mats detect persons and objects in dangerous areas of movement. For example on machines, robots and transfer routes or on automatically closing doors in buses and trains.

Mayser Safety Mats comply with the requirements of the EN 1760-1 and EN 13849 standards. They are designed for large mechanical loads and can be used for millions of switching operations.

Safety Edges SL/NO according to the normally open principle

When Mayser normally open Safety Edges SL/NO are activated, a contact is closed, thus causing a short-circuit. In order to protect people and objects, a signal to the evaluation unit interrupts automatically controlled movement immediately. Mayser Safety Edges are mounted as Anti Pinch Sensors direct to dangerous pinching and shearing edges. For example, on machines, stages or gates. Depending on the run of the closing edge, bend radii are possible.

Stationary Gas Warning System

The Dräger VarioGard 3x00 Transmitter is a VarioGard gas warning system component. A VarioGard system comprises a central unit and various components connected and supplied by a digital VarioGard bus.

High Reliability: Field-proven DrägerSensors in the Dräger VarioGard 3x00 Transmitter measure the concentration of noxious gases in the ambient air. The measured values are digitally transmitted to the central unit for visualisation. If the value exceeds predefined limits an alarm will be triggered. moreMar. 10, 2011

Gas detectors for the monitoring of flammable gases and vapors in the ambient air

The Dräger Polytron SE Ex ... DD sensing heads are gas detectors for the continuous monitoring of flammable gases and vapors in the ambient air. The measurement is based on the heat of reaction principle, where a chemical reaction takes place in a catalytic bead (so-called pellistor) inside the sensor.

By this, concentrations of flammable gases can be detected long before they tend to be ignitable, in other words: before they reach the lower explosive limit (LEL). more
