Barksdale MT1H-H251 Temperature Switch

Barksdale MT1H-H251 Temperature Switch is a remote‑mount, single‑point mechanical thermostat in the MT1H family that uses a copper capillary sensor to actuate a SPDT micro switch at an adjustable set point in the 50–250°F (10–121°C) range. The die‑cast aluminum, anodized housing is IP65 protected (NEMA 4/13 compatible) and terminates through a 1/2" NPT female entry with an internal screw terminal; a cable gland is included for 6–12 mm cables. The copper capillary measures 3/8 inch in diameter and 4-15/32 inches in length, and the sensor temperature limits span approximately -73°C to +149°C. In typical MT1H applications, ambient compensation yields about 0.5% accuracy across its operating range, making it suitable for remote sensing in industrial equipment protection and process monitoring.
