Omron D40A-G9SX-NS BROCHURE
D40A/G9SX-NS
Safety controllers
Compact non-contact door switch/
flexible safety unit
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).
