FANUC A05B-2301-C301 Material Handling Teach Pendant for R-J3

FANUC A05B-2301-C301 Material Handling Teach Pendant for R-J3

A05B-2301-C301 is the FANUC Material Handling Teach Pendant — the complete handheld operator unit for R-J3 / RJ-series robot controllers, with a monochrome LCD, a full keypad and the emergency stop and enabling device built in. This is a complete teach pendant, not a CPU card, a keypad membrane or a housing cover. The full ordering number is written as A05B-2301-C301#MHE1, and MHE1 is printed on the keypad panel in the product photo; the suffix fixes the keypad version. The MHE1 keysheet membrane is also a separate service part, so replacing a worn membrane is a different order from replacing the whole pendant. Other A05B-2301-C3xx numbers in this family belong to different pendant versions or to repair parts such as touch panels, housings and deadman switches. Send us the full number from the pendant back label, the controller nameplate and a photo of the keypad and connector, and we confirm the version before you order.

Specifications

Three things decide the match here: the full number on the pendant back label, the keypad version printed on the panel, and the controller generation. A keysheet membrane, a touch panel or a housing cover is a repair part rather than the complete pendant, and a C311 or C312 pendant is a different order. Send us the full number from the pendant back label, the controller nameplate and a photo of the keypad and connector, and we confirm the version before we quote.

Industrial Applications

• Replacing a complete failed teach pendant on a FANUC R-J3 / RJ-series robot controller.
• Restoring operator control after a damaged LCD, worn keypad, cracked housing or a failed emergency stop or enabling device.
• Keeping a serviceable spare pendant for material handling, palletising, welding and machine-tending cells.
• Rebuilding a used controller or relocating a cell where the original pendant is missing.
• Correcting a spares list that records this number as a CPU card when the fitted item is the complete teach pendant.

Design Purpose

• A complete handheld operator unit that combines the display, keypad and safety controls in one enclosure, so the operator can jog, program and monitor the robot from the cell.
• A monochrome LCD and a fixed function-key layout for the R-J3 generation, so menus and status readouts follow the controller's original interface.
• A defined keypad version marked on the panel, so the pendant is matched to the controller build and the application.
• Built-in emergency stop and three-position enabling device, so the pendant is part of the cell safety chain.
• A circular metal connector at the bottom of the enclosure, so the pendant is exchanged by unplugging its cable rather than by field wiring.

Common Failure Modes

• After the pendant is exchanged, isolate and lock out the controller, connect the pendant cable with the power off and check that the connector is fully seated, then power up and verify the display, the function and numeric keys, the jog keys, the emergency stop, the three-position enabling device and communication with the controller. Retest the emergency stop and enabling circuits at every planned safety inspection.
• No display or an unreadable screen — with the power off, check the pendant cable and connector, then send us a photo of the pendant back label and keypad so we confirm the version.
• Keys do not respond or the wrong characters appear — a worn keysheet membrane is a separate service part. Send us a photo of the keypad panel and we tell you whether you need the membrane or the complete pendant.
• Emergency stop or enabling device does not stop the robot — take the cell out of service and check the pendant and its cable before any further operation. Our FANUC teach pendant range covers related units and parts.
• A C311 or C312 pendant is ordered in place of the C301 — those are other pendant numbers in the same family. Check the number on the fitted pendant back label.
• A repair part (touch panel, housing cover, keysheet membrane or deadman switch) is ordered instead of the complete pendant — send us a photo of the failed item and we identify which one you need.
• The part is ordered from a generic "CPU card" listing — this is a complete teach pendant, not a controller board. Send us a photo of the fitted unit and we confirm it.
