The T-Probe provides an easy to use temperature sensor. The ten foot cable is terminated with a RJ45 Connector, which will facilitate a direct connection to all LINK and LINKHub interfaces. Should a different method of connectivity be required, simply remove the RJ45 connector and replace it with the appropriate type, or hard wire the T-Probe into the bus. There is nothing special about the cable length, it can be shortened or extended to the required length. The maximum length will be determined by the normal 1-Wire bus criteria; available power, bus weight, RFI, etc.

The lower third of the sensing unit is enclosed by a low pressure molding machine. The molding material used is from Macromelt. Click here for detailed specifications. The product type used in iButtonLink products is OM633. The insulation on the cable is PVC. The temperature range of PVC is +60 degrees C (+140 F).

Note: The full temperature range of the sensor (-55C to +125C) is supported by the molding media.

Temperature response and settling times are shown in Appendix 1 of the T-Sense Datasheet, along with full spec sheet on the DS18B20.

All 3 leads of the DS18B20 are brought straight through to the RJ45 connector, giving the user full access to the DS18B20.

The color of the cable may vary.

Custom cable lengths are available; contact us for price and delivery.
