MF1921H iButton Temperature Logger (+15 to +46ºC, 2K), water resistant according to IPX8

The MF1921H provides effective protection against surface moisture, various chemicals and is suited for continuous immersion. The protection class complies with IPX8 according to DIN EN 60529.

To improve the protection class of the iButton it is covered by a rugged and permanent resin coating. Top and bottom provide a notch to enable electrical contact to the iButton. A bracket with mounting hole to mount the unit to an object is also provided.

The permanent resin coating imparts the advantage of the small size of the iButton, however the short thermal response time of an unprotected iButton remains. With suitable accessories the iButton can be comfortably and easily read and programmed even under wet conditions. Compared to the protective encapsulation, the intricate and error prone procedure to place the iButton into the encapsulation and remove it again has been eliminated.

The material employed is an extremely durable and chemical inert resin. This allows an effective protection for the total life span and temperature range of the iButton.

For additional information regarding the protection class, please refer to the application note of this product. Technical information can be found on the DS1921H-F5 iButton Temperature Logger data sheet.
