Why choose this product?

• Specifically defined power supply range of 6 to 36 V DC for use in low voltage DC systems.
• NC switching design for applications requiring a normally closed state.
• Inductive metal detection without the need for mechanical contact with the object being sensed.
• The compact dimensions of 18 x 18 x 36 mm make it easy to integrate into the device design.

Installation and operating instructions

• Install the sensor so that only the designated metal object is within range.
• Before connecting, verify that the supply voltage and electrical parameters of the input or load match.
• During installation, ensure proper cable routing and protection against mechanical damage.
• For reliable operation, observe the correct electrical connection according to the circuit used.

Safety notice

• Incorrect wiring may result in damage to the sensor or connected equipment.
• Only carry out installation and connection when the power supply is disconnected.
• The product is an electrical component intended for integration into equipment, not for stand-alone operation without appropriate protection.
• When used in industrial or mechanical equipment, professional wiring is required.
