Technical Advantages & Materials
Dual-Signal Feedback:
Continuous: 0-1000Ω resistance output via Sakae (Japan) conductive plastic potentiometer.
Discrete: Passive contact (dry contact) signals for "Fully Open" and "Fully Closed" status.
Anti-Backlash Precision:The potentiometer assembly uses a unique spring-loaded mechanism to eliminate gear play, ensuring high sampling accuracy and minimal hysteresis.
Robust Construction:ADC12 die-cast aluminum housing with >0.2mm powder coating, resistant to temperatures above 150°C.
Sealing & Protection:Certified IP68 (Report No: C16040-WT). Equipped with German Oberst double-lip TC oil seals.
