Inductive proximity sensor SN04-D1

The SN04-D1 inductive proximity sensor is used for non-contact detection of metal objects in automation, control and sensing circuits. It is a three-wire DC design intended for installation in machines, fixtures or mechanical assemblies where electrical indication of the presence of a metal target without mechanical contact is required.

Why choose this product?

• Clearly designated model SN04-D1 for DC power supply 5–30 V.
• The square compact design of 18 × 18 × 36 mm facilitates mechanical integration.
• Detection of metal objects without physical contact reduces mechanical stress during operation.
• The three-wire NO version is suitable for common control and sensing applications.

Installation and operating instructions

• Install the sensor so that only the designated metal object is within range and there is no unwanted interference from surrounding metal parts.
• Before connecting, verify the correct supply voltage and wire connection according to the circuit used.
• During installation, maintain the appropriate mechanical position of the sensing surface relative to the detected object.
• The bracket is not included in certain package contents and must be purchased separately if required for installation.

Safety notice

• Incorrect wiring can lead to damage to the sensor or the associated electronics.
• Carry out assembly and electrical connections with the power supply disconnected.
• The product is an electrical component intended for professional or instructed installation in low-voltage DC circuits.
• Protect the sensor from short-circuiting the wires and from overloading the output with an inappropriately connected load.
