Yamaha Conveyor Through-beam Fiber Amplifier E3NX-FA51-3 KLW-M654B-430

Part No.:

• E3NX-FA51-3: General-purpose fiber amplifier module under Omron brand, serving as the core for signal processing.
• KLW-M654B-430: Part number of dedicated track sensor assembly for Yamaha, including brackets, fiber cables and connectors.

Item Name: Through-beam Amplifier / Track Fiber Sensor Assembly for YSM10 & YSM20R

Brand: YAMAHA

Applicable Models:

YAMAHA YSM series mounters, including models YSM10, YSM20, YSM20R, etc.

This assembly is available as original or compatible replacement parts to replace worn or damaged track sensing units.

Function: It is used to detect the position and in-place status of PCBs on the mounter conveyor track.

• Through-beam detection: Fiber emitters and receivers perform through-beam sensing to judge whether a PCB passes through or stays on the track.
• Signal amplification and transmission: The E3NX-FA51-3 amplifier receives weak optical signals from the fiber sensor, converts them into amplified electrical signals and feeds them back to the mounter control system to trigger clamping, pause or continuous mounting actions.

Precautions :

Commissioning & Maintenance: Problems such as failure to clamp boards, equipment alarms or undetected PCBs are usually caused by misaligned fiber optics, incorrectly adjusted amplifier parameters or damaged fiber cables. The YSM20R series generally supports automatic adjustment and reset without complicated manual settings. Ensure the readings of the transmitter and receiver stay normal (reference value above 1600).

Compatibility: E3NX-FA51-3 is a standard universal part, while KLW-M654B-430 is a customized Yamaha kit. Confirm the connector type and cable length match your original machine before purchasing.
