Siemens A6X30138656 Mushroom Pushbutton Body
Panel Compatibility and Mounting
The A6X30138656 is a 22.3mm round panel-cutout body designed for the Siemens SIRIUS 3SU1 modular series. It accepts contact blocks on the rear mount — illumination is not supported on this non-illuminated variant. A separate contact block (Siemens 3SU1 2-pin or 4-pin style) must be ordered to complete the switching function. Panel thickness and bezel compatibility follow the 3SU1 series envelope.
Engineering Verification Checklist
- Confirm contact block series compatibility (3SU1)
- Verify panel cutout is 22.3mm round — not 30mm
- Check that mushroom actuator travel clears adjacent devices at rated extension
- Confirm rohs_val: ROHS3 Compliant meets procurement specification
- Verify product_status: Active for lifecycle planning
- Confirm illumination requirement — this body is non-illuminated only
- Test that actuator retention clip seats fully before panel installation
- Validate that enclosure depth behind panel accommodates contact block stack
