Siemens A6X30137652 — 22mm Round Pushbutton Actuator Body (Non-Illuminated)
Overview
The datasheet must confirm several critical fields before selection can proceed: contact block electrical ratings, IP/environmental protection class, and mechanical endurance cycles are not present in the supplied catalog data. This article addresses the seed part and its catalog-level neighbors in the Siemens 3SU1 22mm switch range.
The A6X30137652 is a Siemens 3SU1 modular pushbutton actuator body, shipped in a box, intended for round panel cutout mounting in a 22mm form factor. It is non-illuminated and requires one or more contact blocks (ordered separately) to form a functional switching element.

Verification required: The supplied fields do not include voltage/current ratings of the contact blocks, IP protection rating, mechanical/electrical life cycles, actuator material, operating temperature range, or torque specifications. Selection must not proceed on electrical ratings until these are confirmed against the official Siemens 3SU1 datasheet.
Ordering-Code / Family Context (verify on datasheet)
Siemens industrial pushbutton components follow a structured ordering-code scheme where the prefix (A6X...) denotes a specific color and operator type within the 3SU1 series. The suffix encodes the button color (37652 = blue). The 3SU1 family covers pushbuttons, selectors, indicators, and mushroom-head operators sharing the same 22mm panel platform and contact block interface. Catalog navigation uses the "Configurable Switch Bodies" path; the actual mechanical coupling to contact blocks is defined in the Siemens 3SU1 device manual.
Integration / Installation Notes
- Contact blocks not included: The actuator body alone does not provide switching contacts. A compatible Siemens 3SU1 contact block (e.g., 3SU1..-..) must be ordered separately and assembled onto the actuator.
- Panel cutout: 22.3mm round hole required; verify that the enclosure boss or housing provides adequate clearance for the actuator collar and any rear-mounted contact blocks.
- Driver / latching behavior: The catalog data does not specify momentary vs. maintained action. This distinction is defined by the contact block or a separate latching module; confirm before ordering.
- Mounting: The 3SU1 system uses a snap-fit or bayonet coupling between actuator and contact block; no screws are specified in the supplied fields.
- Environmental rating: IP code (e.g., IP66 front-face) is not listed; the Siemens 3SU1 family offers variants with silicone boot or sealed collar for harsh environments—select accordingly and verify against the specific actuator SKU.
Selection / Substitution Notes
Substitution of A6X30137652 with any alternate in this catalog row requires confirmation of:
- Identical actuator type and geometry (Pushbutton, Round).
- Identical panel cutout (22.3mm).
- Identical series (3SU1) to ensure contact block mechanical and thermal compatibility.
- Identical illumination (Non-Illuminated) if the application relies on absence of a lamp.
Color substitution (blue vs. red, gray, or clear) is mechanically equivalent but may affect operator intent and standardization in a given machine UI design.
Similar Catalog Parts
| MPN | Title | Shared Spec Keys | Similarity |
|---|---|---|---|
| A6X30137653 | PUSHBUTTON. BLUE | actuator type, illumination, series, requires, panel cutout, encapsulation, compatible series | 1.0 |
| A6X30137651 | PUSHBUTTON. BLUE | actuator type, illumination, series, requires, panel cutout, encapsulation, compatible series | 1.0 |

Why A6X30137653 is similar: Same Siemens 3SU1 series, identical actuator geometry (Pushbutton, Round), identical 22.3mm panel cutout, same non-illuminated construction, and the same requirement for separate contact blocks. The MPN differs only in the color suffix; mechanical and electrical interface are identical.
Why A6X30137672 is similar: Shares the same 3SU1 actuator body platform and panel cutout dimensions; differs only in operator color (red). Red may be reserved for emergency-stop or alarm functions—verify that the application intent aligns with the color change.
Why A6X30137688 is similar: Same 3SU1 series, identical panel cutout, same contact block requirement and non-illuminated style, but the actuator type is Selector (two-position, O-I) rather than Pushbutton—mechanically and functionally distinct for operator interface design.
FAQ
Does A6X30137652 include a contact block? No. The catalog explicitly lists "Requires: Contact Block(s)". A compatible Siemens 3SU1 contact block must be ordered separately to complete the switching function.
What panel cutout is required for A6X30137652? The catalog specifies 22.3mm round. Confirm with the datasheet that the actuator collar and any rear-mounted contact block do not require additional clearance beyond the round hole.
Is this part ROHS3 compliant? Yes. ROHS3 Compliant is listed under rohs_val.
