Allen-Bradley 837-N6 Temperature Control Accessory Brass Well Capillary

837-N6 is an Allen-Bradley brass thermostat well that serves as a temperature switch accessory for electromechanical 837 controls. It provides a remote standard capillary and a rugged brass body designed for mounting sensing where direct immersion isn't practical. The unit features an 8.5-inch bulb size and brass thermostat well construction, enabling reliable remote temperature sensing while protecting the control electronics. It is rated for an external pressure up to 1000 psi at temperatures up to 600°F, suitable for demanding industrial environments. Weighing about 0.68 lb, the 837-N6 integrates with Allen-Bradley 837 temperature control assemblies to extend sensing reach in panels, enclosures, and equipment where accurate temperature monitoring is needed without compromising enclosure integrity. The brass construction offers durability and good heat transfer, and the remote capillary arrangement supports installation flexibility along equipment frames or inside control cabinets. As part of Rockwell Automation's 837 Temperature Controls family, this accessory is specifically the remote standard capillary thermostat well option, enabling reliable, retrofit-friendly temperature monitoring in a wide range of industrial applications.
