Keyence SJ-F700 Multi-Sensor Ionizer (SJF700)
Product Overview
Main Functions
- Ultra – Fast Static Elimination
Uses Variable DC ±8200V corona discharge to neutralize static charges on materials like plastics, films, and electronic parts in about 0.5s, minimizing defects caused by static, such as dust attraction and component damageKEYENCE CORPORATION OF AMERICA.
- Precise Ion Balance Control
The Multi – I.C.C. method maintains an ion balance of ±1V (with SJ – FB01) or ±3V (without), which is critical for protecting sensitive electronic components and ensuring stable product quality in precision manufacturingKEYENCE INTERNATIONAL (BELGIUM) NV/SA.
- Automatic Electrode Cleaning & Maintenance – Free Operation
High – density brushes and an auto – cleaning system keep electrodes free from contamination, eliminating the need for manual cleaning or replacement and reducing maintenance workloadKEYENCE CORPORATION OF AMERICA.
- Real – time Monitoring & Data Logging
The built – in LCD screen displays operating status, ion level, charge level, and other data. It logs data (every 1 hour) and events (errors, alarms, threshold violations) with a 0.1s sampling cycle, enabling traceability and troubleshooting基恩士.
- Flexible Integration with Control Systems
NPN open – collector I/O (max 100mA, ≤40VDC) supports static elimination stop input, ion level alarm, and condition alarm outputs. Ethernet connectivity allows remote monitoring and data transfer to PLCs or PCs基恩士.
- Wide – Area Static Elimination
A maximum air volume of 4.8 m³/min covers an area up to 3m, suitable for large – scale production lines requiring efficient static control across broad surfacesKEYENCE INTERNATIONAL (BELGIUM) NV/SA.
