The S3240 is a flush-mounting NAMUR inductive proximity sensor with a 6.5 mm external diameter and a 1 mm operating distance. It operates on a power supply of 5 to 30 Vdc, with a nominal voltage of 8 Vdc, and produces an output current greater than 3 mA without a target and less than 1 mA with a metal target. The sensor has a maximum operating frequency of 2000 Hz, a repeatability of ≤3%, and is rated IP67 for protection against dust and water. Its case is nickel-plated brass, and it operates within a temperature range of -25 to +70 °C. The model includes a 2-meter PVC cable and complies with DIN 19234 NAMUR standards and the EMC directive.
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.
