The S3261 is a NAMUR-compliant inductive proximity sensor with a flush mounting design, operating at a nominal voltage of 8 Vdc and a supply range of 5 to 30 Vdc. It has an output current of less than 1 mA in the presence of metal and greater than 3 mA in its absence, with an operating distance of 2 mm and an external diameter of M8 x 1. The sensor features a connector interface, nickel-plated brass housing, IP67 protection, and operates within a temperature range of -25 to +70 °C. It supports a maximum operating frequency of 2000 Hz and maintains a repeatability of ≤ 3%. It conforms to DIN 19234 and complies with 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.
