OneWire encapsulated digital temperature sensor IP67 DS18B20 cable 2m

DATASHEET | DATASHEET DS18B20

IP67 DS18B20 encapsulated temperature sensor with 2m cable intended for temperature measurements of solids, loose soils, gaseous and liquid materials. The degree of protection of the sensors is IP 67 according to the EN 60 529 standard.

The sensor has a polyamide container with a diameter of 6, 8 or 10 mm in which the sensitive element is hermetically encapsulated. The sensor is equipped with a shielded cable with PVC insulation up to 105 ° C. The cable has a diameter of 3.5mm and a length of 2m.

Thanks to the Maxim IC DS18B20 digital sensor, the product is immune to disturbances and allows for very high precision. It is connected to the electronic reading devices via 2 cables (ground and mixed signal power supply). The cable shield is not connected internally to the sensor.

The sensor uses the OneWire protocol, used in many industrial and home automation devices, attached information on the sensor and the protocol.
