The
new G10 family of AS-Interface modules from Pepperl+Fuchs uses Connect & Done technology to eliminate
mounting in many applications. At just 40 x 27 x 22mm with IP68/69K protection,
the G10 fits easily into cable ducts and enables quick, convenient sensor
connections using integrated M12 pigtails.
"A lot of AS-Interface connections
are done in cable trays. Now you can take the module, clip it into the cable
and place it in the cable tray," says Helge Hornis, Manager Intelligent Systems
for Pepperl+Fuchs. "There is no need to mount a module anymore which is a significant
simplification in applications where it fits."

"It became obvious that this housing concept is nice, so we discussed the advantages of using this same concept for an actual module with electronics in it," says Hornis. "By altering the mechanical system using the flip mechanism and slightly increasing the size of the housing in one direction, the housing is tiny but big enough for the power electronics. That is, in a nutshell, what the G10 module line is all about."
A typical AS-Interface module has four inputs, or four inputs and four outputs. The G10 has two inputs, or two inputs and one output. As a result, targeted applications have low I/O density needs and where the devices are highly distributed.
In conveyor applications, for example, manufacturers commonly set-up sections that may be 10' long, and each section has a motor. Often, there is a sensor at both the exit of one section and the entry into the next section. Between the two conveyor sections, there are two sensors and the need to control the motor which is exactly what the G10 is designed to do.
"We can turn on/off a motor and sense both when an object goes past the end of one section and enters the next section," says Hornis. "Previously, a user would mount a four input module and run sensor cables or cord sets over various distances. With this design, there is a one meter M12 pigtail on the module, the module is placed close to one of the sensors and you're done."
The G10 is a full-featured AS-Interface module, so it has all of the normal features in terms of diagnostic LEDs, input/output indicators and IP-68/69k protection. The key benefit is that there is no additional M12 connection or cord set required.

At just 40 x 27 x 22mm with IP68/69K protection, ultra-compact G10 AS-Interface modules fit easily into cable ducts and enable quick, convenient sensor connections. Click here to watch video. |
"With a four input module, it is wasteful if you only utilize two sensor inputs," says Hornis. "For applications where the G10 fits, especially low I/O count and distributed operation, this is a solution to a previously difficult to solve problem. In the right circumstances, it will make the engineer's job easier."
The G10 also includes many of the features found in the G11 family introduced in 2010. The design uses the same concentric seal contours around the gold-plated piercing contacts, along with the rugged housing material (PBT) and center stainless steel mounting screw.
IP68/69K rated modules are advantageous in many applications because they provide mounting flexibility. When the housing material exhibits a high degree of chemical resistance and is mechanically well-designed, dripping water, frequent washdowns and cleaning with harsh chemicals are of less concern.
