The safety contact is co-extruded as an integral part of the profile, eliminating the need to 'fish' the safety contact into the profile, significantly reduced assembly time.

The G9SX-GS monitors the machine or robot and operator to make certain they don't enter the co-ordinated area at the same time.
Guarding applications with more than four guard doors can be achieved by combining two or more control units in series.
Each actuator has a uniquely coded element that cannot be reprogrammed, making the actuators secure against manipulation.
The EC Series control unit provides EDM (external device monitoring, also called MPCE monitoring) and may be operated in manual or automatic start mode, which allows the control unit to function as a safety monitoring relay.
Each switch is available in cable lengths up to 25m or with an integral connector to accommodate a variety of application requirements.
Additionally, misalignment tolerance of approximately a 0.5in allows application on machine doors with a high level of vibration or alignment issues, and the control unit's 6A/24V DC switching capability of the control unit allows connection directly to power contactors.
The system works by passing an electromagnetic field from the switch to the actuator, which processes the signal and sends it back to the switch.
It is then read by the control unit, which determines if it matches preprogrammed codes.
"Teach-in" operation teaches the control unit the actuators' codes.
No additional equipment is required to perform the teach-in operation, and there is no limit to the number of teach-in operations that may be performed.
