ON-688 CD3 Control Board for Oshima APS Needle Detector
Professional Replacement & Performance Upgrade
The ON-688 CD3 control board is a purpose-built core component
engineered exclusively for the ON-688 CD3 APS needle detection
machine, ensuring full compatibility with Oshima industrial sewing
and cutting machine systems. As the central processing unit of the
needle detection system, this PCB integrates precision signal
conditioning, multi-probe interface design, and robust relay
control logic to deliver reliable, high-performance metal needle
detection for textile manufacturing environments.
Key Product Features & Advantages
- Optimized Oshima Compatibility: Designed as a direct drop-in
replacement for the original control board in Oshima-equipped
ON-688 CD3 APS models, eliminating complex wiring or software
adjustments and minimizing machine downtime during maintenance or
upgrades.
- Quad-Probe Detection Interface: Equipped with 4 dedicated probe
connectors (2 front probes, 2 rear probes) to enable comprehensive,
high-coverage scanning across the entire material path, drastically
reducing the risk of missed needle fragments or metal contaminants.
- Precision Sensitivity Adjustment: Integrated adjustable
potentiometers allow fine-tuning of detection sensitivity to match
varying fabric thicknesses, needle sizes, and production
conditions, balancing maximum detection accuracy with effective
noise rejection.
- Industrial-Grade Component Selection: Built with high-quality
electrolytic capacitors, resistors, integrated circuits, and relay
modules (JQC-3FF) to ensure long-term stability, resistance to
electrical interference, and reliable operation in high-vibration
factory environments.
- Reliable Actuation Control: Dual relay outputs provide secure,
fail-safe control over machine safety functions such as emergency
stop, alarm triggering, and material sorting, ensuring compliance
with industrial safety standards.
- Robust PCB Design: Multi-layer printed circuit board with optimized
signal routing and component placement enhances signal integrity,
reduces crosstalk, and improves thermal dissipation for continuous
24/7 production use.
