ABB 3HAC046686-001 SMB Replacement Set for IRB 4600

Product Condition	New original or used original. Please confirm the condition with us before ordering.
Shipping	Ships from Shanghai, China. This unit contains a lithium battery (UN3091), so dangerous-goods transport restrictions apply — please contact our Shanghai office to arrange shipping and confirm the lead time.
Buyer Benefits	Genuine ABB 3HAC046686-001 — ABB product name: SMB Replacement Set. Replacement set covering the serial measurement (SMB) function — the position-feedback hardware that lets the controller keep the axis-position reference across power cycles. Supplied as a set rather than a loose board, so the parts that belong together arrive together. Replacement goes with a battery check and the revolution-counter procedure — we flag this before you order, so the planned stop covers the commissioning step. Each unit is inspected before shipment, with electrostatic-safe packaging and full order tracking.
Item Location	Shanghai, China
Payment	We accept PayPal, T/T (bank transfer), and Alibaba Trade Assurance.

Description

SMB Replacement Set for ABB IRB 4600 Robots

Specifications

Part Number	3HAC046686-001
ABB Product Name	SMB Replacement Set
Brand	ABB
Category	Serial measurement (SMB) replacement set — robot position-feedback hardware
Definition	ABB 3HAC046686-001 is the SMB replacement set — the replacement package for the serial measurement hardware that holds the manipulator axis-position reference.
Robot Reference	IRB 4600, per distributor documentation of the ABB article record. Confirm your robot model and serial number against the ABB parts list before ordering.
Function	Restores the serial measurement path: with the set fitted, the controller can again read and retain the manipulator axis-position reference across power cycles.
Set Contents	Not publicly documented. ABB does not publish a component list for this set; ask us for what is included for your robot before ordering.
Installation	Robot base / manipulator SMB compartment
Battery	The set includes battery-backed position retention. It contains a lithium battery — see the dangerous-goods line below.
Dangerous Goods Status	Classified as dangerous goods — UN3091, Class 9 (contains a lithium battery). Air-freight options are very limited, the unit will most likely ship separately from other items on the same order, and it is not handled by the regional distribution centre in Shanghai. Contact our Shanghai office to arrange shipping and confirm the lead time.
Commissioning	After replacement the revolution counters must be verified or updated before the robot returns to production.
Selection Rule	Order by complete article number and robot serial number. This is a set for a defined robot reference, not a universal SMB kit — do not substitute by appearance or by robot family alone.
Net Weight	0.377 kg
Gross Weight	0.377 kg
Dimensions	Not confirmed (not published)
Customs Tariff Number	Not confirmed (published sources are in conflict; classify for your destination)
Country of Origin	Not confirmed (single-source listing; no independent corroboration)
Condition	New original or used original. Please confirm the condition with us before ordering.

Industrial Applications

IRB 4600 cells where the serial measurement hardware has failed and the axis-position reference has to be restored.
Planned renewal of the SMB assembly and its battery before the cell reaches end of battery life, so a scheduled stop does not become an unscheduled one.
Recovery after position data has been lost — revolution-counter update and recalibration with the replacement set in place.
Welding, machine tending and material-handling stations where repeat positioning accuracy matters and losing the axis reference means recalibrating the robot.
Robot refurbishment and relocation work where the measurement hardware is renewed together with the manipulator.

Design Purpose

The serial measurement board is where the robot keeps its sense of position. Axis feedback is collected at the manipulator and the position reference is held there through power-down, backed by battery, so the controller does not have to be re-taught where the axes are every time it starts. When that hardware fails or the battery behind it is spent, the robot loses its position reference, and production stops until the revolution counters are re-established.

ABB supplies the fix for this as a set rather than as individual pieces. That is deliberate: the board, the battery and the mounting parts are matched to a specific robot reference, and mixing a new board with an old cell or the wrong bracket simply recreates the same failure later. 3HAC046686-001 is therefore ordered against a robot model and serial number. It also carries a consequence that has to be planned around — the set contains a lithium battery, so it ships as dangerous goods (UN3091) with limited air-freight options and its own routing, which is why the transport arrangement is confirmed with you rather than assumed.

Before you order and before you install

Plan the shipping first: this set contains a lithium battery and ships as dangerous goods (UN3091). Air-freight options are limited and it travels separately from other items — contact our Shanghai office to arrange the route before you commit to a shutdown date.
Confirm the robot reference: ordered against the IRB 4600 record, but matched by robot model and serial number against the ABB parts list. A set for a different reference is not a substitute.
Expect the position data to be at risk: once the battery path is interrupted the axis-position data can be lost. Budget the stop for the revolution-counter update, not just the physical swap.
Record before removal: note the current revolution-counter values and photograph the connector, battery contact and mounting orientation.
Energy isolation and ESD: de-energize and lock out the robot before opening the SMB compartment, and handle the assembly with electrostatic discharge protection.
Battery handling: do not open, crush or incinerate the battery, and follow the applicable rules for the used unit.
Acceptance: after fitting, verify or update the revolution counters and check positioning before returning the robot to production. Work must follow the applicable ABB robot product manual and be done by qualified personnel.

Common Failure Modes

Battery depleted, so the axis-position data is lost and the robot requires a revolution-counter update and recalibration.
Serial measurement communication not established — the controller cannot read the manipulator position.
Measurement faults that appear intermittently with manipulator movement, pointing at the connector or cabling rather than the board.
Corrosion or moisture at the connector or battery contact in the SMB compartment.
Replacement completed without the revolution-counter update, leaving the robot unable to run its programs correctly.
Wrong set fitted — matched by appearance or robot family instead of by article number and serial number.

Specific alarm codes are not officially documented for this model. Please contact us with the fault code displayed on your controller for accurate diagnosis.

Why Choose Us

Specialized in industrial robot spare parts for ABB, FANUC, KUKA and YASKAWA.
We confirm the set against your robot model and serial number before quotation, so you receive the package for your machine rather than a similar-looking one.
Dangerous-goods handling is arranged up front: we tell you the set ships under UN3091 and work the routing with our Shanghai office instead of leaving it to be discovered at dispatch.
We flag the commissioning step — battery check and revolution-counter update — so a planned stop does not turn into a second outage.
Quote-based service — send your inquiry with the robot model, serial number and the marking on your existing unit for a matched offer.
