Test pull-in and drop-out action for smooth operation and abnormal noise
- Annual Preventive Maintenance
Power off and clean surface with dry soft cloth
Inspect contact wear; replace if wear depth exceeds 1mm
Measure coil resistance to confirm normal status
Lubricate moving parts with small amount of silicone-based grease
- 交換周期

High-frequency cycling: 2 ～ 3 年
過酷な環境 (高温 / 高湿度): 1 ～ 2 年
6.3 Quick Troubleshooting Tips
For LC1K miniature contactors rated 12A for motor control
Check voltage first if coil fails to energize; check core for abnormal noise
Replace unit when contacts burn or auxiliary contacts fail
Regular inspection ensures safety; replace after 5 years service life
- 選定ガイドライン
- 電流定格: Select current ≥ 1.2 times motor rated current. 12A is suitable for motors below 5.5kW.
- コイル電圧: Match coil voltage with control circuit voltage. Common ratings: 24ワシントンDCで, 110Vと, 220Vと.
- 補助接点: 1NO for latching; 1NC for interlock; 1NO+1NC for complex control.
- 配線タイプ: Screw terminals for fixed installation; spring terminals for frequent rewiring.
- Replacement Rule: Prioritize same-series products; verify dimensions and mounting when switching to other series.
