Monnit Part Numbers and SKUs
Monnit corporation utilizes standard part numbers associated with SKU numbers to identify various aspects of a product. The sections of this part number identify things such as the type of product, the radio technology, the radio frequency, and additional options. In some scenarios, you may be able to identify the characteristics of the product by using only the part number.
For the purposes of this article, we will use the part number MNS2-9-W2-HU-RH-L03-NC (Wireless Humidity Sensor - AA Battery Powered) to demonstrate interpretation of the part number.
The individual sections of the part number can be broken down as follows:
MNS2-9-W2-HU-RH-L03-NC
Company - MN (Monnit)
Product Family - S (Sensor)
You may observer G (Gateway) or O (Other) to identify other types products.
Generation - 2 (ALTA 2nd generation radio technology)
A Gen1 devices may not have a number listed herr; or an XL device may display a 3.
Frequency - 9 (900 MHz)
Other frequencies may show 4 (433 MHz) or 8 (868 MHz) to distinguish the radio frequency of the device.
Enclosure/option 1 - W2 (Enterprise/AA)
You may see IN (Industrial), W1 (WIT1/Commercial/Coincell), WF (MoWi/Wi-Fi), or P (PoE-X).
Note: The terms WIT1 and WIT2 were used early in the development of Monnit sensors to represent Coincell and AA form factors. WIT originally stood for Wireless IoT.
Sensor Type/option 2 - HU (Humidity Sensor)
Other common options are: TS (Temperature Sensor), VM (Voltage Meter), CM (Current Meter), AC (Accelerometer), DC (Dry Contact), OC (Open/Closed), PC (Pulse Counter), TC (Thermocouple), and many others.
Type specific/option 3 - RH (Relative Humidity)
Other type specific designations are: LT (Low Temperature), HT (High Temperature), ST (Standard Temperature), and others.
Enclosure/option 3 - L03 (3 foot lead)
Other options you might observer in this position: L10 (10 foot lead),
Enclosure/option 4 - NC (NIST certified)
