3SU1136-0AB40-1BA0

1. Overview

The Siemens 3SU1136-0AB40-1BA0 is a complete illuminated pushbutton assembly from the SIRIUS ACT 22mm command and signaling system. It features a plastic body with a metal (matt, sand gray) front ring, a green flat/flush actuator, momentary contact action, 1 NO contact, and an integrated LED module rated for 230V AC. The part is classified under Siemens' "Plastic with metal front ring, matt, 22 mm" product line within the SIRIUS ACT family. Per the Siemens SiePortal and Industry Mall, this product is phased out / discontinued; the successor is referenced as 3SU1106-0AB40-1BA0.

2. User Sentiment

No direct forum or user review data was found in the research findings for this specific part number. The product appears on eBay.de with positive seller feedback and buyer comments noting suitability for "Anlagen- und Fördertechnik" (plant and conveyor technology), suggesting real-world industrial use. Its presence across multiple global distributors (DigiKey, Farnell, RS, Mouser, Kempston Controls, EU Automation, CJS Automation, Radwell) with active pricing indicates it was a widely-adopted industrial pushbutton before discontinuation.

3. Real-World Applications

The 3SU1136-0AB40-1BA0 is used in industrial control panels, conveyor systems, plant machinery, and manufacturing equipment requiring panel-mount illuminated pushbuttons. The 22mm standard mount size, IP66/IP67/IP69K ingress protection, and 230V AC LED rating make it appropriate for harsh factory environments including washdown areas. Its classification as a "pilot device" by Radwell confirms typical use as a machine start/stop or status indicator button.

5. Ordering & Compatibility

DigiKey price was $177.31 per unit (box quantity), with no stock and a 4-week manufacturer lead time (as of data collection). The product was available from DigiKey (PN: 3473-3SU11360AB401BA0-ND), Mouser, Farnell, RS Components, Kempston Controls, CJS Automation, EU Automation, Radwell, and WI Automation worldwide. Chinese market pricing was approximately ¥207.51. Laser-labeled variants with custom text/symbols exist (suffixes -Z Y10 through Y15+). The component actuator (3SU1031-0AB40-0AA0) is separately orderable and compatible with the standard 3SU1 system. Successor 3SU1106-0AB40-1BA0 should be used for new designs.

6. Known Issues

DATA QUALITY FLAG — ACTUATOR STYLE MISMATCH: The catalog entry names this product "SIRIUS ACT Green Illuminated Raised Button" and sets subcategory: extended-illuminated, but ALL official Siemens datasheets, distributor listings, and RS Online consistently describe the actuator as FLAT (Button, flat / Druckknopf flach / Flush). RS Online title explicitly says "Flush." DigiKey/Mouser also say "FLUSH." The catalog's "Raised/Extended" description is incorrect for this part — flat/flush is the correct actuator style. Additionally, one Amazon.de listing title described the product as "White" — this is a mislabeled Amazon entry; green is confirmed by all authoritative sources. An eBay.de listing also uses the same PN for a "rot" (red) unit, which is likely a different color variant listed under the wrong PN.
