3M 1421-XR/iD EMS iD ball marker - telephone, orange

The orange 3M EMS iD ball marker - Telephone makes marking and subsequent location of underground telephone lines extremely easy. It can be located to a maximum depth of 1.20 metres, is insensitive to minerals, chemicals and temperature changes and is therefore suitable for all types of soil. The free-floating design in a watertight PE sphere ensures that the marker always aligns itself exactly horizontally, regardless of the installation position. The liquid inside the sphere is a mixture of water and propylene glycol, which is biodegradable and harmless to humans, fauna and flora. The electronic markers are considered the most reliable method of marking existing or newly installed facilities - even under snow. Their function is not affected by metal ducts or pipes, fences or high-voltage power lines. The EMS iD markers are supplied with an individual, pre-programmed serial number. This serial number is also attached to the marker in the form of a removable, self-adhesive sticker with a barcode and can be stuck directly onto the cable/location plan. If the ball marker receives the "Read"-Signal from a 3M Dynatel cable locator, it transmits the information previously stored in it. The iD markers can be temporarily or permanently programmed to store user-defined information such as cable or joint data, type of application or other important details. Once this data has been read by the locator, it can be transferred to a PC via a serial RS232 connection. These active iD ball markers are also compatible with older, passive markers.
