Omega’s PR-21 series of RTD (resistance temperature detector) sensors with M12 connector feature a welded 316L stainless steel housing and an integral four-pin M12 connector for easy connection. They provide a fast response time and a temperature range of -50°C to +250°C. The series is suited for process control and test and measurement applications. The sensors can be used in any two-, three-, or four-wire application by selecting one of two available wiring arrangements and using only the necessary wires. This enables simplified installation with a variety of applications because it can be connected as-is with most measurement or control equipment when combined with a four-pin female M12 connector extension or patch cable.
