The S3270 NAMUR Inductive Proximity Sensor from Fargo Controls, Inc. operates on a nominal voltage of 8 Vdc, with a load resistance of 1K ohms. It is designed to detect metal targets, exhibiting an output current of less than 1 mA in their presence and greater than 3 mA in their absence. This sensor can function within a variable voltage range of 5 to 30 Vdc and has an operating frequency of up to 2000 Hz. The S3270 is compliant with NAMUR standards (DIN 19234) and features an IP67 protection degree, making it suitable for harsh environments. It can operate within a temperature range of -25 to +70 ¬8C. The sensor is available in a connector version and is compatible with various amplifiers, including ALNC, ALTP, and ALN2 types. The S3270 is designed for applications requiring reliable proximity sensing in industrial settings.
Working Principle
These sensors act as a variable resistor. With the active surface free, they have a low output resistance. In the presence of a metal target the output resistance is high. The resulting variation in the current is used to control a signal amplifier.
Technical Characteristics
Nominal voltage: 8 Vdc (7,7 - 9V) - Load resistance 1K ohms Output current: In the presence of metals < 1 mA Output current: In the absence of metals > 3 mA These sensors can be used in a variable voltage field from 5 to 30 Vdc.
Amplifiers
All the NAMUR sensors can operate in connection with the following amplifiers: ALNC type for 1 sensor; ALTP delayed type for 1 sensor or ALN2 type for 2 sensors. Furthermore, they can be connected to the electronic rotation controls CRTP.
