Honeywell Bi-Metallic Thermostat, Closes at 65 °C, 186 °C Max Close On Rise, Open On Rise, Open, Automatic Reset, SPST,

This thermostat is a control device designed to respond to temperature changes in demanding commercial and aerospace settings. It operates automatically to restore contact after temperature falls, and is intended for integration where precise switching based on thermal thresholds is required. The unit is built for environments that demand recognised industry approvals and robust electrical switching capacity.

• SPST configuration provides straightforward single-circuit switching
• 10A switching capability supports moderate-load circuits
• 250V AC contact rating suits common industrial supply voltages
• Automatic reset restores operation without manual intervention
• Closing threshold set at 65°C for defined trip behaviour
• Rated to 186°C maximum operating temperature for high-heat tolerance

• Suitable for thermal control in automation panels within aerospace systems
• Ideal for temperature monitoring on industrial electrical enclosures
• Used for overtemperature protection in mechanical assemblies
• Can be used for thermal switching in electronics manufacturing equipment

The device offers single-pole switching with contacts that either close or open as temperature rises, providing both close-on-rise and open-on-rise switching behaviours to suit differing control schemes.

Connections are provided via solder tab terminals designed for secure soldered joints in Compact assemblies and for reliable signal integrity in vibration-prone environments.

It is specified to operate from a minimum of 0°C up to a maximum of 186°C, accommodating both ambient and elevated thermal conditions typical of industrial and aerospace locations.

The component carries multiple recognitions including space qualification and certifications from UL, VDE and CSA, Plus compliance with Mil-PRF-24236 and acceptance by NASA for relevant applications.
