Ashcroft LTA Series Temperature Switches

Prevent unneeded activation with adjustable deadband
  • Quick, accurate response via SAMA Class II vapor pressure thermal system
  • Choose the switch to meet your needs—wide variety of lengths and temperature ranges available
  • Easy to operate and install—meet NEMA 4, 4X, and IP66 requirements
Single set point, adjustable deadband, SPDT switches feature epoxy-coated aluminum systems for reliable performance. Choose direct-mounting units with rigid probes—great for use with 3/8" nominal bore thermowells in areas with high vibration, velocity, or pressure. Remote-mount units have spring-mounted capillaries with 302 stainless steel armor and include a 1/2" NPT(M) bushing adapter.
