3M EMS 1401-XR is a spherical passive marker designed for marking and locating underground telephone lines installed at depths of up to 1.5 metres. The device enables quick identification of underground infrastructure routes without the need for an external power supply.
The marker is equipped with a special self-levelling mechanism that keeps the locating element in the correct position regardless of how the marker is placed in the ground. This enables precise detection of the marked infrastructure using compatible locators.
The 3M EMS 1401-XR is designed for permanent marking of underground telecommunications infrastructure. Placing the marker near an installation makes it possible to identify its location later during excavation, renovation or maintenance work.
The marker can be used, among other applications, to mark:
Precise identification of the marked asset helps reduce the risk of accidental damage to infrastructure during excavation work.
One of the key features of the 3M EMS 1401-XR marker is its self-levelling design. The mechanism maintains the correct horizontal position of the locating element regardless of how the spherical marker is placed in the ground.
As a result, the marker remains correctly oriented relative to the ground surface, allowing it to be reliably located after burial.
The EMS 1401-XR marker is designed for installation at depths of up to 150 cm. This makes it possible to mark infrastructure located below ground level without the need for additional excavation work in order to identify it later.
This is particularly useful during subsequent modernisation work, network expansion and excavation carried out near existing infrastructure.
The marker has a waterproof housing made of polyethylene, designed to withstand demanding underground conditions.
The housing is resistant to:
This allows the marker to remain buried for long periods while retaining its functional properties.
The 3M EMS 1401-XR is a passive marker and therefore does not require an external power source during normal operation. This allows it to be permanently installed underground and subsequently located using a suitable locating device.
The absence of power cables or batteries simplifies installation and reduces maintenance requirements.
Inside the sphere is a mixture of water and propylene glycol, which is readily biodegradable in the natural environment. The material used is not harmful to people or animals.
The marker has a spherical design with a diameter of 10.4 cm, providing suitable durability and protection for the components located inside the housing.
Its compact form makes it easy to install in the ground close to the infrastructure being marked.
The 3M EMS 1401-XR is intended for contractors, network operators and teams involved in the construction and maintenance of underground telecommunications infrastructure.
It can be used both during the installation of new networks and when modernising existing cable routes. Marking underground infrastructure helps streamline future maintenance work and reduces the risk of accidental cable damage.
3M EMS 1401-XR is a durable, self-levelling spherical marker designed for marking and subsequently locating underground telephone lines. With an installation depth of up to 1.5 m, a robust housing and passive operation, it provides a practical solution for marking telecommunications infrastructure during construction, modernisation and subsequent maintenance work.
