Inductive proximity sensor SND04-P

The ROKO SND04-P inductive proximity sensor is used for non-contact detection of metal objects in industrial and automation applications. The version with PNP NO output is intended for direct current power supply 10–30 V DC and for installation in places where switching is required depending on the presence of a metal target. The sensor is equipped with a connection cable and mounting holes in the sensor body.

Why choose this product?

• Clearly marked model and wiring directly on the sensor label
• Combination of 10-30V DC power supply and PNP NO output for general control applications
• Inductive sensing principle designed for detecting metal objects
• IP67 protection and integrated protection circuits listed by the manufacturer on product materials
• Design with mounting holes allows for a solid mechanical attachment

Installation and operating instructions

• Before connecting, verify the correct polarity of the power supply and the function of the individual wires according to the markings BN, BK and BU.
• Install the sensor so that it detects only the metal target in the working area.
• Route the cable away from places where there is a risk of mechanical damage, pulling or kinking.
• Perform installation with the power disconnected.
• When integrating into a control system, verify the input's compatibility with the PNP NO signal.

Safety notice

• The product is an electrical component for DC power supply; incorrect connection may cause damage to the sensor or downstream circuits.
• Do not connect the sensor to a voltage outside the range of 10–30 V DC.
• Avoid shorting wires and do not install under voltage.
• Installation in industrial equipment must be carried out by a qualified person.
• When used in safety-critical functions, it is necessary to verify whether the sensor is intended for such use in the device documentation.
