077F8761 by Danfoss

The 077F8761 cable assembly is produced by Danfoss within the Danfoss Cables and Accessories series. It is a prewired temperature-sensor lead that links an NTC sensing element to a control board in HVAC or refrigeration equipment, allowing the control system to monitor thermal conditions and adjust compressor or fan operation as needed. In refrigeration racks, it carries the sensor signal to logic modules that supervise defrost cycles and alarm thresholds, so temperature changes can be detected quickly during operation. This arrangement lets the controller respond to changing temperatures without requiring a separate field wiring run.

Its cable length of 1.5 m gives enough reach between the evaporator space and the controller enclosure without leaving excessive slack. A RAST2.5 Edge connector mates directly with standard board headers on low-voltage assemblies, which helps keep installation neat and reduces the chance of wiring mistakes. The assembly has a gross shipping weight of 0.047 kg and uses 3 conductors for the sensor circuit. The sensing element is an NTC thermistor, so its resistance falls as temperature rises and the controller can interpret that change for regulation and protection functions.

The net installed weight of only 0.044 kg adds very little load to PCB headers or cable routing supports, which is useful in compact enclosures. Packed volume is 0.197 L, so multiple assemblies can be stored in a small service package without taking up much space. The conductor insulation and plug geometry are matched to the original application, helping the lead fit correctly in refrigeration and HVAC assemblies that use this connection style. Because the cable is supplied as a complete assembly, the connector and sensor wiring arrive in one matched piece for straightforward installation. The compact cable format also supports clean routing between the sensing point and the board, especially where space around the evaporator housing or electrical compartment is limited.
