Passive Connector Kit for Legacy FANUC CNC Wiring
The FANUC A02B-0120-K303 is a connector assembly with a 15-pin female connector and cover, intended for wiring in legacy FANUC CNC systems. As a passive component, it carries no supply voltage rating of its own and draws no independent power; all electrical characteristics follow the host CNC. The official FANUC identity per B-64303EN/01 lists a recommended cable connector (Hirose, 20-pin), while the hardware kit is described as Hirose FI40B-2015S plus FI-20-CV, soldering type, for JA3 on an operators panel with 80 mm minimum depth. Because the cross-generation manual is not confirmed for this specific order code, verify the exact pin count and mating configuration with AutoDCSTech before purchase.
How Does the A02B-0120-K303 Differ from Other Connector Options?
Buyers comparing legacy CNC connectors should note that this order code is a spare-part kit rather than a generic field connector. The table below contrasts This unit with common alternatives using only verified data.
- unit: 15-pin female connector with cover; Hirose FI40B-2015S and FI-20-CV soldering kit; for JA3 operators panel, 80 mm minimum depth.
- Official manual reference: B-64303EN/01 identifies a Hirose 20-pin cable connector; this is a family-level reference, not confirmed for this order code.
- Generic passive connectors: No FANUC-specific mating guarantee; pin count and case style vary by supplier.
- Active interface modules: Include communication ports and independent power consumption; This unit has neither.
Consequently, This unit suits replacement and maintenance of existing Series 16/18 wiring where the original connector style is known. It is not a universal adapter.
Key Specifications and Environmental Limits
The following parameters are extracted from the available documentation. Values marked not applicable reflect the passive nature of the component.
- Brand: FANUC
- Model: unit
- Series: FANUC CNC accessory
- Connector kit: Hirose FI40B-2015S (connector) + FI-20-CV (case), soldering type
- Application: JA3 on operators panel, 80 mm minimum depth
- Supply voltage: Not applicable (passive component; powered by host system)
- Power consumption: Not applicable (passive component; no independent power consumption)
- Operating temperature: Not applicable (rating follows host CNC)
- Storage temperature: Not applicable (rating follows host CNC)
- Relative humidity: 75%RH or less normal; up to 95%RH for short periods (≤1 month), no condensation
Because the connector is passive, its current-carrying capacity and isolation performance are determined by the host CNC and the installed cable. No separate voltage or current rating is published for this kit.
Installation and Maintenance Guidance
Installation requires soldering the Hirose FI40B-2015S connector to the cable and fitting the FI-20-CV case. Confirm that the operators panel provides at least 80 mm depth for JA3 mounting. During routine maintenance, inspect for loose pins, solder cracks, and case damage. Keep the connector dry; humidity should remain at or below 75%RH under normal conditions, with short excursions to 95%RH acceptable for no more than one month and without condensation. Since This unit is a legacy spare part, verify current lifecycle status and availability with AutoDCSTech before ordering.
Integration and Support
This unit contains no communication ports or active electronics. It therefore integrates only as a passive wiring interface within the host CNC cabinet. For engineering-grade precision in matching this connector to your existing Series 16/18 wiring, contact AutoDCSTech with your exact requirements for precise matching.
