Festo
547477
Pressure sensor SDET-22T-D2-G14-I-M12
The Festo part number 547477 is a piezoresistive pressure sensor designed to measure relative pressure across a 0 to 2 bar range with an overload capacity of 5 bar and 1.5 % FS accuracy. Operating on an 8 to 30 V DC voltage range with short-circuit strength and polarity protection for operating voltage, this component features a 4-pin M12x1 round plug electrical connection conforming to EN 60947-5-2 with a PBT plug housing. It processes gaseous, liquid, and compressed air media within a -10 to 100 °C temperature range while supporting ambient temperatures from 0 to 80 °C, delivering a 4-20 mA analog output over a two-wire connection. Built copper- and PTFE-free, the unit carries the CE symbol according to the EU-EMV guideline and holds C-Tick and c UL us - Listed (OL) authorizations.
