Product Details
LS48 / LS55 / LU1 Inductive Proximity Sensors – Plastic Housing Series
The LS48, LS55, and LU1 inductive proximity sensors are compact, non-contact metal detection solutions designed for reliable performance in diverse industrial automation environments. With flexible output options, IP67-rated protection, and support for both DC and AC power (where applicable), these sensors deliver consistent accuracy in metal object detection.
Key Features (Series Common)
- Flexible Power Supply: Supports 10…30VDC for all models; LS48/LS55 also compatible with 90…250VAC for broader integration
- Configurable Output: PNP/NPN output options with NO/NC/NO+NC states (LS48/LS55) or NO/NC states (LU1) to suit different control systems
- Durable Plastic Housing: IP67 protection grade, resistant to dust, moisture, and common industrial contaminants
- Wiring Flexibility: Available in cable or connector versions for convenient on-site installation and maintenance
