- Quick and easy mounting

Fibre optic systems are used where mounting space for photoelectric standard sensors is restricted. The evaluation unit and the fibre optics are mounted separately.
These systems can therefore be installed in places where access is difficult.

Fibre optic systems are designed as through-beam or diffuse reflection sensors.

Acrylic fibre optic sensors are suited for standard applications if no particular demands such as heat or chemical resistance are made. They can be cut to length and are less expensive than glass fibre optic sensors.

Fibre optics made of silicate glass are more resistant to heat, ageing and chemicals than acrylic fibre optics. They do not change their optical response when they are bent. Glass fibre optic sensors cannot be cut to length by the user.

High-flex fibre optics allow extremely small bending radii.

Electronic fuses permanently monitor the 24 V secondary circuit and reliably switch it off in the event of a failure. These electronic circuit breakers will also switch off circuits in cases where mechanical circuit breakers often do not trigger, e.g. in case of overload of a circuit with long cables.
The system has a modular structure and consists of a feed module and side-by-side mountable fuse modules. These modules can be mounted next to the head module via a simple clip mechanism, completely without any bridges or jumpers. Easy mounting and minimised wiring complexity save cost and time. With the standard version the user can connect up to 10 and with the IO-Link version up to 8 safety modules to the feed module.
The fuse modules feature an LED for signalling if the module has triggered, if it is active and in how far it is utilised. Each module is equipped with two channels. By means of a pushbutton, each channel of a fuse module can be activated, deactivated or reset individually. The IO-Link version allows remote configuration and operation of the modules.

Proximity switches
- Dual inductive sensor for pneumatic actuators and valves
- Designed for simple fit to common actuators based on VDI / VDE 3845
- Quick and easy installation of the AS-i dual sensor
- Position feedback for rising stem valves with up to 80 mm stroke
- Reliable permanent valve monitoring

Valve sensors
In industrial processes where liquids, air or gases are used, valves are needed for dosing and control. Pneumatic valve actuators are normally used for mechanical positioning. The valve position must be monitored electronically.

Dual sensor for valve actuators
A round target, also called a 'puck', with two metal screws offset by 90° is mounted on the actuator shaft. The screws are located at a different height. A compact dual inductive sensor (type IND) with two integral sensors detects the upper or lower metal screw depending on the valve position and thus the two switch positions. This system operates reliably with no wear at all. It is virtually resistant to external influence and insensitive to mechanical stress such as vibration and shock.

Sensor for rising stem valves
For position feedback on rising stem valves efector valvis is used. Two or three switch points can be set via pushbuttons over a stroke of 80 mm. In addition to the "open" and "closed" positions of the valve, a third position is used for "seat lift" monitoring (active during the cleaning process). Thanks to a resolution of 0.2 mm the sensor detects even very small changes in the position of the valve. The inductive measuring principle guarantees wear-free non-contact operation. Different adapters allow for easy installation of the same sensor on valves of various manufacturers and sizes.

Inductive sensors
- Wide operating temperature range
- High protection rating for the requirements of harsh industrial environments
- Reliable detection due to low sensor tolerances
- Reduced storage due to wide range of applications

Inductive sensors are nowadays indispensable for industrial applications. As compared to mechanical switches they offer almost ideal conditions: non-contact operation free from any wear and tear, high switching frequencies and accuracy. In addition, they are insensitive to vibration, dust and moisture. Inductive sensors detect all metals without contact.

Position sensors are nowadays indispensable in industrial applications to reliably detect positions on machines. Compared to mechanical switches, inductive, capacitive and magnetic sensors offer ideal characteristics: non-contact operation free from any wear and tear, high switching frequencies and accuracy. In addition, they are insensitive to vibration, dust and moisture.
Cylinder sensors are used for position detection of pistons in pneumatic cylinders.
In industrial processes where liquids, air or gases are used, valves are needed for dosing and control. Valve sensors reliably signal the positions of valve actuators, valves, slides and flaps.
Photoelectric sensors as "artificial eyes" are fundamental to automation technology. They are used where reliable and non-contact detection of the exact position of objects is required. The material of the object to be detected is of no importance. Compared to inductive, capacitive and magnetic sensors, photoelectric sensors have a much larger sensing zone.
Laser sensors are used for the detection of very small objects. In combination with time-of-flight measurement, even long distances can be measured reliably.

Laser sensors
- Reliable detection of tiny objects
- Simple alignment due to visible red light
- Simple switch point setting via pushbutton
- Sensors for special applications
- Accurate fine adjustment by means of system components

Laser sensors are used where small objects or precise positions are to be detected. They are designed as through-beam sensors, retro-reflective sensors or diffuse reflection sensors.

Laser light consists of light waves of the same wave length with a fixed phase ratio (coherence). This results in an important feature of laser sensors, that is the almost parallel light beam.
The result: Long ranges can be achieved thanks to the small angle of divergence. The laser spot which is clearly visible even in daylight makes the alignment of the system easier.

- Extensive range of system components for easy and secure mounting

Automation technology can no longer be imagined without photoelectric sensors as "artificial eyes". They are used where a reliable and non-contact detection of the exact position of objects is required. The material of the object to be detected is of no importance. Compared to inductive sensors, photoelectric sensors have a much greater sensing zone.

Through-beam sensors are distinguished by a long range. The system consists of two separate components: a transmitter and a receiver. The light only covers one way (from the transmitter to the receiver). Adverse effects in the applications, such as dust in the air, dirt on the lenses, steam or mist do not immediately interfere with the system.

For retro-reflective sensors the transmitter and receiver are incorporated into one housing. By means of a reflector the transmitted light is returned to the receiver. Retro-reflective sensors without polarisation filter operate with infrared light, systems with polarisation filter with visible red light.

Diffuse reflection sensors are used for the direct detection of objects. The transmitter and receiver are integrated into one housing. The transmitter emits light which is reflected by the object to be detected and seen by the receiver. The light reflection from an object is evaluated. Therefore additional functional components (such as reflectors for retro-reflective sensors) are not needed for the operation of a diffuse reflection sensor.

In highly automated industrial processes the colour is often a selection criterion for detecting, sorting or inspecting various products and goods. Both the colour of a product itself and the packaging, labels or imprints can be precisely detected using electronic colour sensors.

With contrast sensors, print marks and very flat objects can be detected easily and reliably.

Sensors for the detection of transparent objects consist of a retro-reflective sensor with polarisation filter and a very fine prismatic reflector. They safely detect glass, film, PET bottles or transparent packaging and can be used for counting bottles or glasses or monitoring film for tear.

Photoelectric level sensors detect levels of bulk materials and non-transparent liquids without contact.
