Siemens A6X30143997 — Configurable Switch Lens

Overview

The A6X30143997 is a Siemens operator interface front element from the 3SU1 series, specifically a red, raised round lens designed to serve as the visible actuator cap on a modular 22mm industrial pushbutton station. The part is classified under "Configurable Switch Components" and carries an Active product status with ROHS3 Compliant marking. The data source did not provide front-element dimensions, mounting method, cap material, compatible contact-block model numbers, or applicable safety standards (such as IEC 60947-1 or UL 508) — all of which must be confirmed from the Siemens 3SU1 datasheet before commit to a bill of materials.

Key Parameters

Not provided (critical — verify against datasheet):

• Front-element outer diameter or height (raised profile dimensions)
• Cap material (polycarbonate, ABS, etc.) and surface finish
• Lens attachment method (snap-on, screw, bayonet) and required body mating depth
• Panel-cutout requirement (the alternates reference 22.3mm round cutouts for complete pushbutton bodies — the lens alone may have different integration requirements)
• Maximum actuating force or torque on lens surface
• IP rating of assembled unit (lens plus body plus contact block)
• Compatible contact block series and quantity (some 3SU1 bodies list "Requires Contact Block(s)")
• Operating temperature range

Integration / Installation Notes

The 3SU1 series follows Siemens' modular 22mm operator interface architecture, where front elements (lenses, raised caps, illuminated modules) are ordered separately from the switching body and contact blocks. A complete functional pushbutton requires at minimum: a lens/cap, a body (A6X30143907, A6X30143908, etc.), and one or more contact blocks (not listed in supplied fields). The alternates listed under "Configurable Switch Bodies" share the same series and round panel cutout of approximately 22.3mm, suggesting the lens is designed to seat into those bodies. The user should cross-reference the 3SU1 system diagram to confirm which body variants accept the raised round cap and what lens-retaining hardware (if any) is required. Panel builders should also confirm that the red color code corresponds to the intended function (typically STOP/emergency in IEC 60204-1 practice) and that any machine-risk assessment does not impose a specific material or actuation-force limit not captured in this catalog entry.

Selection / Substitution Guidance

Substitution of A6X30143997 with a different color or shape from the same 3SU1 series (e.g., green raised cap from the same family) is possible provided the target color and shape match the machine's operator-interface specification. The following alternates share the same series but differ in color or component type:

Why they appear similar

The three alternates share the same brand (Siemens), series (3SU1), and packaging encapsulation, which drives their similarity scores. A6X30143907 is the red variant of a complete pushbutton body (not just a lens) and shares the red color; however, it is a body assembly with integrated actuator, not a standalone lens. A6X30143908 is a green extended-stroke pushbutton body, sharing the series and form factor but differing in color and type. A6X30143984 is an LED illumination module — same series, different function. None of these are direct drop-in replacements for the raised round red lens; they are either different colors, different component types (body vs. lens vs. illumination), or both. The only valid substitution for the lens itself would be another Siemens 3SU1 raised round red lens, and the catalog does not list one. Verify via the Siemens 3SU1 ordering catalog.

FAQ

Q: Does the A6X30143997 include a contact block or switching body? A: No. This entry describes a lens only (Configurable Switch Lens). A complete pushbutton requires a separate body and at least one contact block; the compatible body cutout is approximately 22.3mm round based on alternate entries in the same series.

Q: What panel cutout is required for the assembled pushbutton? A: The catalog fields do not specify the cutout for the lens alone. Based on the 22.3mm round cutout stated for the alternate body entries (A6X30143907, A6X30143908, etc.), the full assembled unit (lens + body + contact block) uses a 22.3mm round aperture. Verify with the Siemens 3SU1 system datasheet.

Q: Is the red color code (STOP/Emergency) verified for safety-function use? A: The catalog does not provide functional assignment or safety rating (SIL/PL) for this lens. Color-to-function mapping in Siemens 3SU1 follows IEC 60204-1 conventions (e.g., red = STOP), but the specific machine-risk assessment and safety standards applicable to the end installation must be reviewed separately.
