Thermostat Washer Temperature Sensor for Controllers A compact, mountable temperature sensor with a 5 mm washer hole, available as thermocouple Type K, Type J, or PT100. Designed for direct connection to compatible temperature controllers, with braided cable for flexible routing and improved durability. Key benefits Simple installation: 5 mm washer hole allows secure mounting to panels, flanges, or fittings without special adapters. Clear compatibility: Choose Type K, Type J, or PT100 to match the input of your temperature controller for reliable readings. Flexible lengths: Braided cable available in 0.5 m, 1 m, 2 m, and 3 m lengths to suit different installation distances. Wire length includes washer length. Robust handling: Braided cable reduces abrasion and flex fatigue in routine industrial or workshop use. Broad temperature coverage: Supports a wide range of temperatures depending on sensor type for many applications. Specifications Mounting: 5 mm washer hole Sensor types and typical measurement ranges: Type K: 0 to 600 C Type J: 0 to 400 C PT100: 200 to 500 C Cable: Braided cable, available lengths 0.5 m, 1 m, 2 m, 3 m (measured including washer) Form factor: Washerstyle probe for throughpanel or threaded mounting Compatibility note Type K and Type J sensors share the same external appearance but use different internal materials and output characteristics. The sensor type must match the temperature input type of your display or controller. If your controller is configured for K, use a K sensor. If configured for J, use a J sensor. Typical use scenarios Industrial temperature control: Mount the washer probe to an oven door, heating plate, or process line and connect to a temperature controller for process regulation. Laboratory or test equipment: Secure the sensor to a fixture or sample holder for repeatable measurements across experiments. Furnace, kiln, or HVAC monitoring: Use the temperature range of Type K or PT100 to monitor elevated process temperatures or environmental conditions. What this sensor solves Eliminates guesswork in mounting small probes by providing a standard 5 mm washer attachment point. Provides the appropriate sensor type and cable length to match controller inputs and installation requirements. Reduces cable wear with a braided outer layer for longer service life in workshop and industrial settings. Ordering guidance Select the sensor type that matches your controller input: Type K, Type J, or PT100. Choose the cable length that covers the distance from mounting point to the controller. Remember that the listed cable length includes the washer length. This washerstyle temperature sensor offers a practical, easytoinstall solution for many temperature measurement and control needs where a compact, mountable probe and durable braided cable are required.
