Model Number Structure - Omron G9SX Series Manual

Compact Non-Contact Door Switch/Flexible Safety Unit
D40A/G9SX-NS
Electronic Detection Mechanism for Better
Stability in Non-contact Door Switch
Operation
• Stable operation reduces Controller errors caused by unstable
doors.
• Connect up to 30 Non-contact Door Switches with LED
indicators to one Controller.
• Reversible switch provides flexibility in installation.
• Two-color LED indicator enables easier maintenance by
identification of door status and cable disconnections.
• Safety category 3 (EN 954-1).
• Both Non-contact Door Switches and conventional Key-type
Safety-door Switches can be input to one Controller, saving
space.
• OFF-delay output provided for stop category 1.
• Easily construct partial stop and complete stop systems with the
logical AND connection function, using G9SX as the Controller.
