3.3 EC type examination
The AIRSKIN® Safetyflange has undergone an EC type examination in accordance with the Machinery Directive
2006/42/EG with the number MG17-00411; this was carried out by TÜV AUSTRIA.
3.4 Connection to the safety controller
Just like any AIRSKIN® Pad, the AIRSKIN® Safetyflange functions autonomously and automatically makes de-
cisions about the current state (“actuated”, “not actuated”, “defective”). The AIRSKIN® Safetyflange can be con-
nected on its own or in series with other additional AIRSKIN® Pads. Besides the robot itself, it is also possible to
encase the gripper with AIRSKIN® Pads. As soon as the Safetyflange or any sort of Pad detects an actuation or
fault, it opens the safety lines and duly signals this to the controller. In addition to the two safety channels, every
AIRSKIN® Pad is supplied with
24 V
direct current (SELV, PELV).
Not potential-free!
The semiconductor switches that are incorporated in AIRSKIN® are not potential-free. One
must therefore ensure potential equalization between the AIRSKIN® Connection Box and
the robot controller.
3.5 Components
The AIRSKIN® Safetyflange consists of the flange (mechanical component) with a bias spring and plain bearing,
together with an AIRSKIN® Pad (sensor). The AIRSKIN® Safetyflange is pre-assembled and must not be modified
or disassembled by the user, except for exchanging the optional bias spring.
3.5.1 Dimensions of the AIRSKIN® Safetyflange
shows the basic dimensions of the AIRSKIN® Safetyflange. The AIRSKIN® Pad manifests a manufac-
turing tolerance of up to
1 mm
.
3.5.2 Flange adapter
The AIRSKIN® Safetyflange can be configured for various types of robot. In order to achieve this, there are different
robot flange adapters that will enable the AIRSKIN® Safetyflange to be attached to the robot. The robot gripper
can be attached to the AIRSKIN® Safetyflange by using the corresponding tool flange adapter.
Any type of robot that matches the assembly patterns listed below is supported:
• ISO 9409-1-50-4-M6,
• ISO 9409-1-40-4-M6 or
• ISO 9409-1-31.5-7-M5 and/or ISO 9409-1-31.5-4-M5
