The R130 Dry Contact Tag, a battery-powered RF transmitter that attaches to assets that need to be tracked, located and monitored, features two twisted wires that enable connection to a dry contact device. Once connected, the R130 will monitor and report the open and closed states of the device. While the connected device is in either an open or closed state the tag will beacon the dry contact status once every 10 seconds. When the dry contact state changes the tag will immediately broadcast three beacons at 0.5 seconds apart with the new dry contact status then return to beaconing once every 10 seconds.

The R130 tag can be mounted using either the industrial-strength adhesive backing or by using the supplied plastic screw mount. The R130 Dry Contact Tag cases are impact resistant and temperature stable. The R130 tag battery life is typically 5-7 years with a 10-second beacon rate with no more than 250 switching cycles per day. Based on the ratings and specifications from the battery manufacturers, RF Code develops usage models to calculate the life of the active RFID Tags. Like all models, there are assumptions and approximations involved. The values are to be taken as engineering estimates – not guaranteed performance. Exposure to extreme temperatures will shorten the battery life. RF Code warrants all tags to be free from defects in materials and workmanship for a period of 1 year.

The R130 Dry Contact Tags have a minimum switching time of 200ms for both open and closed state transitions. Meaning, the R130 tags are only intended to be used with devices that will be in the open or closed states for more than 2/10ths of a second. If the dry contact device switches from one state and back faster than 200ms the tag will not report the state change.

The R130 tag should be mounted within a few feet of the dry contact device. It is recommended that the wire connecting the dry contact device to the R130 tag is less than 10 feet in length.
