Siemens A6X30139936 — 3SU1 Series Illuminated E-Stop Actuator
Overview
The A6X30139936 is a Siemens 3SU1 series front-mounted emergency stop pushbutton actuator in an illuminated, 40mm round mushroom configuration. It ships as a configurable switch body that requires separate contact blocks and an illumination source to become operational. The part carries ROHS3 Compliant status and is active in the Siemens catalog.
3SU1 Series Design Integration
Actuator and Illumination Specifications
The actuator type is classified as E-Stop, Round with integrated illumination. The part requires a contact block assembly and an illumination source (lamp or LED) to complete the switching function. The 22.3mm round panel cutout is standard across the 3SU1 platform, supporting retrofit into existing 22mm cutout enclosures without modifications.
Panel and Mechanical Context
The encapsulation style is listed as Box, with a panel cutout dimension of 22.3mm (Round). The part is packaged individually and is compatible with the broader Siemens 22mm operator component ecosystem (3SU1 series). No hold-in/latching mechanism is specified in the catalog data; for applications requiring maintained contact after actuation, the datasheet or Siemens configurator tools should be consulted.
Similar Catalog Parts
The following parts share the 3SU1 series platform, same illumination type, and identical panel cutout dimensions. All require contact blocks and an illumination source. Selection should be based on actuator function:
| Spec | A6X30139936 | A6X30139906 | A6X30139946 | A6X30139927 |
|---|---|---|---|---|
| Actuator Type | E-Stop, Round | Pushbutton, Mushroom | E-Stop, Round | Pushbutton, Mushroom |
| Illumination | Illuminated | Illuminated | Illuminated | Illuminated |
| Panel Cutout | 22.3mm (Round) | 22.3mm (Round) | 22.3mm (Round) | 22.3mm (Round) |
| Series | 3SU1 | 3SU1 | 3SU1 | 3SU1 |
| Similarity | — | 0.96 | 0.96 | 0.96 |
Why these are similar: All four parts share the Siemens 3SU1 series, identical illumination configuration, compatible series designation, and the same 22.3mm round panel cutout. The primary distinction between A6X30139936 and A6X30139906 lies in actuator function (E-Stop vs. standard mushroom pushbutton), while A6X30139927 differs by actuator type despite the same mushroom-family designation. A6X30139946 mirrors the E-Stop classification of the seed but lacks the "40mm" size qualifier in its title.
