Rotary encoders with functional safety are becoming more important in factory automation applications. Certified safety rotary encoders from Pepperl+Fuchs enable simple integration in applications with high safety categories up to SIL3 (in accordance with IEC 61508).
In this example, a safety relevant application is shown. The certified, functionally safe rotary encoder detects the rotational motion of a pipe-cutting saw. The rotary encoder provides safe operation of the machine, as required in accordance with the standards listed in the machinery directive 98/37EG and also in accordance with the new directive 2006/42/EG and IEC 61800-5-2.

Pepperl+Fuchs Rotary Encoders with Functional Safety
Pepperl+Fuchs Retro-Reflective Area Sensor
The new RLG28 retro-reflective area sensor from Pepperl+Fuchs has a 60 mm constant detection field and a resolution of 12 mm over a range of 0...4 m. RLG28 allows the consistent detection of small objects within the entire detection area.
The sensor is an ideal replacement for current standard products that do not fully satisfy requirements. Installed in a standard 28 series photoelectric sensor housing, users can replace their existing 1-beam solution 1:1 with a 100 % problem solver without modifying the control concept.
Areas of application include the material handling, packaging and automotive industries.
The RLG28 specializes in the reliable detection of object front edges such as different types of pallets, sacks, packaged or reflecting goods. The sensor is also suitable as an ejection control for falling objects, an overhang control, e.g. by way of deformed blocks, and can also be used as a muting sensor.
Pepperl+Fuchs AS-I G11 Modules with Innovative Clean Housing Design
The AS-Interface field modules offer an innovative clean housing concept in a robust, compact, round design, and are particularly suitable for assembly machinery and process automation applications.
Cleaning processes involving steam cleaners, pressure washdowns, and high mechanical stresses do not affect the performance of G11 modules. You can connect sensors and actuators to an AS-Interface quickly and easily, even under these harsh ambient conditions.
Advantages of the AS-Interface G11 modules:
- No more troubleshooting, because overload conditions are indicated directly at the affected M12 port.
- Secure mounting and robust materials for extra durability
- Device fits into every corner due to compact, round design
- Steam cleaning or pressure washdowns never pose a problem due to radial O-ring seals with IP68/IP69k protection
- Connected to AS-Interface directly on the module or via AS-Interface passive splitter and M12 connection

Phoenix Contact CLIPLINE THERMOMARK X1.2 Thermal Transfer Printer

- The new material holder allows for center alignment as the material feeds through the print head. That means you no longer have to adjust the optic eye for every change in material.
- A firmware upgrade allows for less waste when aligning the material.
- The newly designed cutter (purchased separately) has the ability to perforate as well as fully cut endless shrink sleeves.
- Like all Phoenix Contact printers, it runs on CLIP PROJECT marking software.
Phoenix Contact QUINT SFB 48VDC/10A Power Supply

- Worldwide input voltage range - 85-264 V AC and 90-350 V DC
- Adjustable output voltage of 30-56 V DC - Wide range of applications
- Power Boost - 13 A Power Boost provides ample current for starting additional loads
- Extended diagnostics - Indication of both DC OK and Power Boost Modes

Phoenix Contact M12 Connector for Fiber Optics
The de-facto standard in signal transmission can now be used for quick data transmission with fiber optics as well. The new M12 fiber optics connectors from Phoenix Contact now offer especially small connection solutions that can be used for the connection of POF, PCF and GOF fibers.
The IP65 and IP67 degrees of protection make the connectors ideal for use in the industrial environment. The design of the connectors protects the sensitive ferrules and fiber end surfaces during contacting and assembly.
Alternatively, pre-assembled lines are also available. Panel feed-throughs with an integrated transceiver or couplings can be used for the integration of the M12 fiber optics connection into electronic or control cabinet housings. The transceiver integrated in the panel feed-through allows direct opto-electrical conversion.
