Ø D1 L2 L3 L1 L1, L2, D1: See table Electrical Data D2 = 4 mm, L3 = 50 mm Notes (1) Vishay NTC Thermistor chip with epoxy coatings and special potting resins (2) ABS plastic cap of refrigerator white color (3) Double insulated cable, cylindrical, PVC/PVC, 2 x 0.35 mm2 (4) Conductors’ end insulation non stripped MOUNTING The plastic housing can be inserted in a pocket inside the refrigerator cabinet. The plastic housing can be assembled with the refrigerator cabinet backside, with the help of adhesive tape, then foamed. The plastic housing can be inserted on a pipe welded on the evaporator tube. The plastic housing can be clamped on the evaporator tube with the help of a clip. Suitable for PCB Edge connection, or plugged in a wire-to-wire connector, or assembled in a terminal block. DESIGNERS CORNER • Other Resistance-Temperature curves are available, based on Vishay 2381 640 0xxxx series, or specific customer’s curve. • Other lead length and other standard plastic caps, like Ø 6 mm x 25 mm, Ø 7 mm x 25 mm, Ø 8 mm x 30 mm, Ø 9 mm x 30 mm, Ø 9 mm x 49 mm, 7 mm x 7.5 mm x 25 mm or customer specific sensor shapes, are available on request. • Single insulated cables and Class I sensors can also be supplied. • The sensors can be supplied without connector, with end-wire stripped, with crimped connectors, sealed connectors, or insulation displacement connectors (e.g. rast 2.5 mm). Consult Vishay for the list of available connectors. • Several sensors can be grouped on the same connector, with the same or different shape. • Additional features, like connection to the door switch, can also be included on the grouping connector. • Visual aids, like cable jacket colors or position markers can be added to optimize customer's assembling process. • The cable harness associated with the sensor can be provided as a total solution. DESIGNERS TOOLS • 3D Solid Models (STEP or IGES) or 2D Models (DXF, DWG) are available • 3D solid models: www.vishay.com/doc?29106 • NTC curve computation: www.vishay.com/resistors-non-linear/curve-computation-list/ Revision: 12-Oct-12 Document Number: 29095 2 For technical questions, contact: [email protected] THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
