Hermetically sealed reed switch sensor with temperature-compensated circuitry, featuring reverse polarity protection and short-circuit prevention. The dual-color LED (red/green) provides visual status indication for power and output states. Designed for high-vibration environments with shock resistance up to 100m/s² (IEC 60068-2-27).
- Pneumatic cylinder position detection in automation lines
- Safety door interlocks in injection molding machines
- Elevator car position monitoring systems
- Material handling equipment limit switches
- Hydraulic press stroke control
- Conveyor belt synchronization sensing
Installation guidelines:
Maintain 3x sensing distance between adjacent sensors. For optimal performance in ferrous metal environments,
use non-magnetic mounting brackets (stainless steel 304/316 recommended).
Maximum lateral offset tolerance: ±1.5mm from magnet centerline.
