Siemens Illuminated pushbutton, plastic, green, 1NO+1NC, 22mm Part number 3SU1102-0AB40-1FA0

Product Overview

The 3SU1102-0AB40-1FA0 is an illuminated, flush-mount pushbutton from the SIRIUS ACT 3SU1 series. It features a round, 22 mm panel-mount button with green actuator and integrated LED, offering a single command point — ideal for control panels and operator interfaces where clear visual signalling and reliable switch operation are required. The button is rated for industrial use with high protection against dust, water, and wash-down, making it suitable for harsh environments.

Key Features

• Illuminated pushbutton (complete unit), SIRIUS ACT 3SU1 series
• Round actuator, 22 mm panel cut-out
• Green flat pushbutton — easy to recognise for “start”, “enable”, or status-on functions
• Momentary (push-to-make) contact operation
• 1 command point with 1 NO + 1 NC contact module (i.e. SPDT contact configuration)
• Integrated LED module (24 V AC/DC) for illumination — with LED status indication
• Screw-terminal connection — secure and robust wiring
• High protection class: IP66 / IP67 / IP69K when mounted correctly — dust-tight, water-/jet-wash resistant
• Insulation rating up to 320 V, suitable for typical low-voltage control circuits
• Rugged mechanical design: shock and vibration resistant — industrial-grade reliability

Applications

The 3SU1102-0AB40-1FA0 is ideal for control-panel applications requiring illuminated push-button control: start/reset buttons, control signalling, status indication, operator interfaces or panel controls. Particularly useful in industrial automation, machinery controls, food & beverage, water treatment, packaging, or any environment where robust, water- and dust-resistant user inputs are needed. Also suitable for wash-down or outdoor-exposed panels due to high ingress protection ratings.
