SIEMENS BERO 3RG4143-6AD00

<h2>Siemens BERO 3RG4143-6AD00 Inductive Proximity Switch</h2> <h3>Description</h3> <p>The Siemens BERO 3RG4143-6AD00 is a robust inductive proximity switch designed for non-contact detection of metallic objects. It features a large sensing distance of 65mm and operates within a wide voltage range of 10 to 65 V DC. Housed in a durable rectangular enclosure with an IP65 rating, this sensor is well-suited for various industrial automation applications, including conveyor systems, positioning tasks, and machine control. Its PNP output with a changeover contact (NO/NC) provides flexible integration options.</p> <h3>Specifications</h3> <ul> <li>Manufacturer: Siemens</li> <li>Product Series: BERO</li> <li>Part Number: 3RG4143-6AD00</li> <li>Type: Inductive Proximity Switch</li> <li>Sensing Distance (Sn): 65 mm</li> <li>Operating Voltage: 10 – 65 V DC</li> <li>Output Type: PNP</li> <li>Switching Current: 300 mA</li> <li>Switching Function: Normally Open (NO) / Normally Closed (NC) Changeover</li> <li>Protection Class: IP65</li> <li>Housing Material: Plastic</li> </ul> <h3>Label Info</h3> <ul> <li>U: 10 – 65 V DC</li> <li>I: 300 mA pnp</li> <li>Sn: 65mm</li> <li>IP 65</li> </ul> <h3>Application</h3> <p>This sensor is ideal for use in factory automation, logistics, material handling, and manufacturing machinery where reliable detection of metal parts from a distance is required. Common applications include position sensing on conveyor belts, detecting the presence of machine parts, and controlling automated processes.</p> <h3>Country of Origin</h3> <p>Germany</p> <h3>CO2 Impact</h3> <p>By purchasing this pre-owned sensor, you help avoid the emission of approximately 18 kg of CO2. This saving is comparable to the emissions from driving a car for 90 kilometers or charging a smartphone 2160 times. Choosing refurbished components is a smart decision for both your budget and the environment.</p> <h3>Availability</h3> <p>This is an obsolete item, no longer in production by Siemens. Availability is limited to existing stock. The direct successor recommended by the manufacturer is the Siemens 3RG4143-6CD00.</p> <h3>FAQ</h3> <strong>What is the difference between a PNP and NPN output on a sensor?</strong><br><p>A PNP (Positive-Negative-Positive) sensor sources current, meaning it provides a positive voltage output when activated. An NPN (Negative-Positive-Negative) sensor sinks current, meaning it provides a path to ground (negative) when activated. The choice between PNP and NPN depends on the input requirements of your PLC or control device, with PNP being more common in Europe.</p> <strong>What does “non-flush mountable” mean for this sensor?</strong><br><p>Non-flush mountable means that the sensor’s active face must protrude from the surrounding metal mounting surface. A metal-free zone must be maintained around the sensing head to prevent interference with the inductive field, which could reduce the sensing distance or cause false triggering. This design allows for a larger sensing range compared to a flush-mountable version of the same size.</p> <strong>Can this DC sensor be protected against reverse polarity?</strong><br><p>Yes, most modern industrial DC sensors from reputable manufacturers like Siemens, including the BERO series, have built-in reverse polarity protection. This prevents damage to the sensor’s internal electronics if the positive and negative supply wires are accidentally swapped during installation.</p> <p>Order now from spareparts2day for expert support and fast delivery.</p> <p>Last Update: Friday, March 13, 2026</p> <p><em>spareparts2day is not an authorized distributor, reseller or representative of the products featured on this website.
