At BERNSTEIN, you can choose from a wide range of position switches with different designs and actuator variants. However, with such a large selection, it is sometimes not so easy to find the right product for your requirements.
That's why we've put together a general overview of our position switches with plastic and metal enclosures. Typical areas of application and the different designs form the basis here.
Position switches with plastic enclosure
All BERNSTEIN position switches with plastic enclosures fulfil protection class 2.
| Design | Miniature | Compact | Flat | General purpose | Bistable | Heavy duty | ||
| Typical Applications | Confined space | Multiple applications | Monitoring of covers, position detection of moving machine parts, monitoring of sliding doors | Serial wiring | Thanks to their modular design, they can be used for all applications in mechanical and plant engineeringRough environment, Monitoring of doors, flaps, Protective guards and position detection of moving machine parts | Rough environment, Monitoring of doors, flaps, Protective guards and position detection of moving machine parts | ||
| Series | → C2 | → Ti2 | → I49 | → Bi2 | → IN62 | → IN65 | → I81 | → IN73 |
Position switches with metal enclosure
Position switches with a metal enclosure can withstand high mechanical stresses. They are also suitable for applications in which hot chips and sparks are produced, for example.
| Design | Flat | Heavy duty | |||
| Typical Applications | Installation in machines and plant components that require a flat design and high degree of protection, for monitoring covers and inspection flaps, also outdoors | Rough environment, also outdoors | Safety applications and position monitoring | Serial wiring | Very rough environment |
| Series | → M49 | → MN78 | → GC | → SN2 | → D |

Safety switches and safety sensors monitor the movable guards of a machine or system. They ensure that users cannot open them as long as a dangerous situation exists. This is because there may still be a risk even if the machine has already been stopped.
A classic example of this is overrunning saw blades. It is imperative that the operator is denied access until the dangerous movement has come to a complete stop.
Inductive sensors
An inductive position sensor detects metallic objects. It consists of 4 functional groups:
- Coil
- Oscillator
- Threshold switch
- Switching output stage
Capacitive sensors
A capacitive position sensor detects materials in a solid or liquid state. It consists of the following 4 functional groups:
- Sensor electrode
- Oscillator
- Threshold switch
- Switching output stage
Magnetic sensors
BERNSTEIN offers the following variants of magnetic position sensors:
- Electromechanical magnetic switches with reed contact
- Electronic magnetic sensors based on the Hall and magnetoresistive principle
