The S3268 is a NAMUR indutive proximity sensor with a 10 mm operating distance, M18 x 1 thread, and non-flush mounting. It operates from a power supply of 5 to 30 Vdc with an operating frequency up to 1000 Hz and repeatability of ≤ 3%. The sensor has a nickel-plated brass case, IP67 protection, and an operating temperature range of -25 to +70 °C. It features a connector C2 interface and conforms to NAMUR standards (DIN 19234) 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.
