Contactless Safety Technology
The use of contact-free locking facilities, in particular for monitoring movable safety guards, offers the following advantages: * Simple adjustment, * No broken actuator, *High degree of tolerance to vibrations, moved doors and hoods, * No wear Exceptionally easy cleaning.

Capacitive Sensors
Capacitive proximity switches detect conductive and non-conductive materials that can be in a solid or liquid state. They serve the purpose of monitoring product levels in containers, checking contents in filling and packaging systems as well as detecting, positioning, monitoring and counting objects, e.g. in sequence control systems, conveyor belts.

Inductive Sensors
In general, inductive proximity switches consist of four basic elements: a coil, an oscillator, a threshold switch and an output stage with short-circuit protection.The oscillator generates a high frequency, electromagnetic alternating field which is emitted from the active face of the coil.Eddy currents are induced in a metal object that enters this field. These eddy currents draw energy from both the electromagnetic field and from the oscillator which is consequently attenuated.The more energy taken the closer the metal object moves towards the active face. The threshold switch switches on the output stage at a defined attenuation value.In proximity switches with a DC voltage supply, this switch is designed as an NPN transistor which switches the connected load to the negative pole or as a PNP transistor which switches the load to the positive pole. The output stage is a thyristor or a triac in AC voltage switches.

Magnetic Switches / Magnetic Sensors
BERNSTEIN offers electromechanical reed contact magnetic switches and electronic versions which operate according to the Hall and magnetoresistive principle.The electronic versions are characterised by their enhanced mechanical properties (extremely high resistance to vibration, shock or impact) and are not prone to wear in operation. Thanks to the use of only one single “active” component (reed contact), “traditional” electromechanical magnetic switches are extremely reliable in operation. The universal current capability and low procurement costs allow these switches to be used in a wide range of applications.
