Omega's PR-21 series RTD sensors feature M12 connectors
Omega introduces its PR-21 series of RTD sensors with M12 connector which features an all welded 316L stainless steel housing, an integral 4-pin M12 connector for a temperature range of -50 to 250 degrees Celsius (-58 to 482 degrees Fahrenheit). The PR-21 series is designed for process control and test and measurement applications. These RTD sensors can be used in any 2, 3 or 4-wire application by selecting one of the two available wiring arrangements. This allows the PR-21 series sensor to be used for a wide variety of replacement applications since it can be connected as-is with just about any measurement or control equipment available when combined with a 4-pin female M12 connector extension or patch cable.
