More Information

Overview Manuals Cylinder-Switch Fit Mounting Steps Acceptance Check Product Applications

Features:

  • Direct-mount role: Position a compatible SMC auto switch on the supported cylinder mounting feature.
  • Table-controlled fit: Select from the cylinder and switch combination rather than bracket appearance.
  • Service inspection: Judge mounting integrity and sensing stability separately from normal finish variation.
BMG2-012 is a model-specific mounting bracket whose fit depends on the cylinder and auto-switch combination.

Correct installation keeps the switch stable at the intended detection point without forcing the bracket or fastener.

Acceptance should confirm model marking, mechanical fit and repeatable sensing before the cylinder returns to automatic operation.

For BMG2-012 sourcing, Apter Power can help confirm the SMC cylinder series, bore size and auto-switch model before quotation.

  • Combination decision: Confirm the cylinder series, bore and switch model together; matching only one element does not establish bracket fit.
  • Switch change: Recheck the official table whenever the switch family changes, because the existing bracket may no longer position or retain it correctly.
  • Geometry stop: Do not bend or machine a bracket that does not sit in the mounting feature; the mismatch indicates an incorrect combination.
  • Model control: Keep the complete bracket code on the maintenance record so a similar shape is not treated as interchangeable.
  • Initial fit: Seat the bracket in the intended cylinder feature before tightening so the fastener does not pull a misaligned part into place.
  • Switch position: Set the sensing point through the documented adjustment method and then secure it, preserving repeatable detection.
  • Tool control: Use the specified small tool and tightening method; excessive force can damage the screw or shift the switch.
  • Rework decision: Loosen and reposition the assembly instead of forcing it when the detection point is wrong.
  • Functional proof: Cycle the cylinder and confirm repeatable switch operation before returning the machine to automatic service.
  • Movement check: Reinspect bracket and screw seating if the detection point drifts, because movement can create intermittent machine-state feedback.
  • Finish judgment: Do not reject the bracket solely for lot-related chromate color or gloss variation when model and mechanical condition are correct.
  • Damage stop: Replace a bent, cracked or non-retaining bracket rather than relying on adjustment to recover stable sensing.
  • Cylinder position sensing: Hold a compatible switch at the required detection point on a supported SMC cylinder with verified bracket fit.
  • Machine sequencing: Provide stable switch positioning so repeatable end-position feedback can support the intended automatic sequence.
  • Maintenance replacement: Restore an identified bracket-and-switch arrangement after damage or loss of retention has been confirmed.
  • Spare control: Separate visually similar brackets by their approved cylinder and switch combination before stocking or installation.
Description
BMG2-012 is an SMC direct-mount bracket used to position a compatible auto switch on a supported cylinder. The official selection tables make the cylinder series, bore and switch family part of the bracket decision.

BMG2-012 should be accepted by model and mounting fit rather than finish appearance alone. SMC notes that chromate color or gloss can vary by production lot without reducing the stated corrosion resistance.
Alternative Names
BMG2012
Technical notes
BMG2-012 is the mounting component selected by cylinder series, bore and auto-switch model. An incorrect combination can prevent stable switch positioning, while excessive force on the small switch screw can damage the mounting arrangement. Follow the SMC mounting sequence and specified tightening method, and stop when cylinder or switch identity is unresolved.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
When a technician changes the auto-switch model on a cylinder, can BMG2-012 remain installed without review?
Recheck the official cylinder-and-switch table before retaining the bracket. A different switch family can require another mounting arrangement, and a loose or mispositioned sensor may produce unreliable machine-state feedback.
If BMG2-012 does not sit naturally in the cylinder mounting feature, should it be bent to fit?
Stop the installation and verify the cylinder series, bore and bracket code. Altering the bracket would hide a selection mismatch and can prevent the switch from holding a stable detection point.
When the sensed position drifts after several cycles, how should BMG2-012 be inspected?
Hold automatic operation and check bracket seating, switch position and fastener retention before readjusting the sensor. Continued movement can create intermittent feedback and unexpected sequence stops.
If a new BMG2-012 has a different chromate shade, does that justify rejecting it?
Accept or reject it from model identity, damage and mounting fit rather than color alone. SMC states that lot-related color or gloss variation does not by itself reduce the stated corrosion resistance.
What proves BMG2-012 is correctly installed before a machine returns to service?
Cycle the cylinder and require repeatable switch operation at the intended point with no bracket movement. A tight screw alone does not prove correct sensor position or stable feedback.
If the small mounting screw will not tighten normally, may extra force be used on BMG2-012?
Stop and inspect the screw, bracket alignment and switch seating instead of increasing force. Over-tightening can damage the mounting parts and still leave the sensor unable to hold its position.
