Mitsubishi Electric MR-D05UDL3M-B is a 3 m Safe Torque Off (STO) connection cable for the CN8 safety interface. Mitsubishi Electric lists the exact model as a dedicated option and identifies material number 227986 in its current regional product catalog.
- Manufacturer: Mitsubishi Electric
- Exact model: MR-D05UDL3M-B
- Material number: 227986
- Product type: Safe Torque Off (STO) cable
- Cable length: 3 m
The cable carries two STO input channels and the associated monitor/output conductors documented for the CN8 interface: STO1, STO2, STOCOM/24G, TOF1, TOF2 and TOFCOM/24V. These names describe the official connection diagram; they are not independent cable ratings. The B-suffix configuration is documented for safety controllers other than MR-J3-D05. Keep MR-D05UDL3M-B distinct from MR-D05UDL3M and from the 0.3 m and 1 m variants; a similar model number is not evidence of the same controller-side termination or approved use. Before installation, verify the exact cable label, the host drive and safety-controller manuals, connector set, pin assignment, routing and STO validation procedure. Country of origin, HS code and unqualified shipment weight are not published here because exact official evidence was not found.
Important Notice: Verify the complete cable label, host drive, safety controller and CN8 pinout. Do not merge the B-suffix cable with related MR-D05UDL variants.
Apter Power MR-D05UDL3M-B Manuals and Guides
Both documents are model-specific and compiled only from the cited Mitsubishi Electric official sources. Confirm the physical label and current host-system manuals before installation.
STO safety-controller connectionConnects a supported Mitsubishi Electric drive CN8 interface to an approved safety controller other than MR-J3-D05.
Machine safety retrofitSupports evidence-led replacement of an existing 3 m B-suffix STO cable after exact host and pinout verification.
Commissioning and validationProvides the documented STO1/STO2 and TOF monitoring conductors used during an engineered safety validation.
Maintenance spares planningSeparates material number 227986 from shorter or differently terminated MR-D05UDL cable variants.
Follow the exact Mitsubishi Electric drive and safety-controller instructions. Treat this cable as part of a validated safety function, not as a generic interconnect.
1Verify the complete MR-D05UDL3M-B label and material number 227986 before installation.
2Confirm that the safety controller is not MR-J3-D05; Mitsubishi Electric assigns a different 3 m cable for that controller context.
3Do not substitute MR-D05UDL3M, MR-D05UDL03M, MR-D05UDL1M or an EG open-end variant without an exact approved wiring review.
4De-energize the drive and follow the machine's approved lockout, discharge and functional-safety procedures.
5Use the host drive and safety-controller manuals to verify CN8 pin numbering, connector orientation and conductor destinations.
6Do not treat signal names as independent voltage, current or safety-integrity ratings for the cable.
7Route and secure the 3 m cable according to the equipment and machine-builder requirements; inspect for damage, strain and connector contamination.
8After installation, perform the complete STO proof test and verify both STO channels and TOF monitoring behavior before operation.
9If STO is not used, follow the applicable Mitsubishi Electric instruction for the supplied CN8 short-circuit connector; never improvise a bypass.
10Origin, HS code and shipment weight remain unpublished until exact Mitsubishi Electric evidence or the physical package label is available.
