Mitsubishi RJ001A connector board, assembly number BN634B559G51, is a compact PCB with two parallel black multipin connector housings. REACO CNC supplies this board for maintenance and replacement enquiries, with identification assistance, a testing video before shipment and worldwide express delivery.

The solder side is marked RJ001A and BN634B559G51. The connector side carries the Mitsubishi logo, RJ001 and Made in Japan markings. These details help compare the replacement with the original assembly.

Connector Layout and Product Scope

The photos show both connector housings, the exposed contact arrangement and the reverse solder side. Compare the connector orientation, populated contact positions, housing ends and PCB outline with your original board. Confirm any required mating boards, cables or additional fittings separately when ordering.

RJ001A and BN634B559G51 Identification

Use RJ001A / BN634B559G51 as the primary replacement reference. Keep BN634B559H01, JCI-01SA and JCI-01SB as additional identification details. These markings should be checked together rather than treated as interchangeable assembly numbers.

Fitment Confirmation

Send clear photos of both sides of the original board, its installation position and the host equipment nameplate. Match the assembly number, revision labels, connector keying and contact arrangement before selecting a replacement. Similar connector housings alone do not establish compatibility.

Testing and Order Support

Contact REACO CNC with the required quantity, preferred condition and delivery country. We will confirm the actual board, included parts, testing scope and dispatch estimate. A testing video is provided before shipment.
