Technical features
Housing: dimensions 43 × 35.2 × 34.5mm (without terminals and bush thread).
Bulb and capillary: stainless steel, with a 100mm long PVC sleeve on the capillary. PTFE sleeving for ranges of 300°C and above. Other sleeving lengths on request. Minimum capillary bending radius: 5mm. For temperature ranges above 300°C, the capillary has a PTFE sleeve over its full length except 150mm on the bulb side.
Temperature sensing element: oil-filled bulb and capillary.
Caution: temperature ranges above 400°C are filled with sodium-potassium eutectic. In case of breakage of the bulb or capillary, this liquid may self-ignite at room temperature in the presence of water or moisture.
Terminals: 6.35 × 0.8mm quick connect terminals, 90° bent. Straight terminals or 30° or 60° bent terminals are also available on request (MOQ applies). Terminal positions and alignment allow the use of a connector with flat or bent terminals.
Adjustment: factory fixed setting, up to 550°C.
Mounting: M10×1 center bush (M8 on request).
Grounding: 6.35 × 0.8mm quick connect terminal as an option.
Contact: SPDT or SPNC.
