【English Introduction】
OH8002D Hall Effect Proximity Switch is an industrial-grade solution for rotational speed measurement, position detection and motion control applications. Utilizing advanced magnetic field sensing technology, it delivers stable signal output in challenging working environments with enhanced operational reliability.
Key Advantages:
- Wide Voltage Compatibility: Operates at 10-30V DC, adapting to diverse industrial power systems while resisting voltage fluctuation interference.
- High Load Capacity: 200mA direct-drive output enables connection with relays and counters without additional amplification circuits.
- Environmental Resistance: Functions reliably at -40℃ to +85℃ with reverse polarity protection and EMI resistance, suitable for vibration-intensive and contaminated environments.
- Speed Measurement Optimization: 5kHz response frequency accurately captures magnetic variations within 0.1mm air gap, supporting rotational speed monitoring from 50 to 50,000 RPM when paired with ferromagnetic gear discs.
Applications:
Ideal for motor speed monitoring, conveyor belt velocity detection and automated positioning systems. The compact cylindrical housing (M18×1 thread) allows easy installation, while IP67 rating ensures durability in dusty or humid conditions. Proprietary magnetic compensation algorithm effectively eliminates cross-interference in multi-sensor arrays.
Technical Specifications:
• Sensing Range: 0-5mm adjustable
