S3248 is a non-flush mounting NAMUR inductive proximity sensor with a 10 mm operating distance and an M18 x 1 thread. It operates on a supply voltage from 5 to 30 Vdc, with a maximum switching frequency of 1000 Hz and a repeatability of ≤3%. The sensor has a nickel-plated brass housing, IP67 protection, and an operating temperature range of -25 to +70 °C. It conforms to NAMUR standards (DIN 19234) and complies with the EMC directive. The model is available with a 2-meter PVC cable.
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.
