2 Overview

General description

Magne is an electromagnetic process lock that is designed without any moving parts, which means it is
hardwearing and ideal for industrial applications and harsh environments. Magne can keep a door or cover locked
with a holding force of up to 1500 N. When the power is then broken, magnetic materials will not stick to the
surface
Magne 3 is an electromagnetic lock that can be complemented by any choice of external interlocking device.
The Magne 4 variants are electromagnetic locks with an integrated Eden safety sensor for secure interlocking
protection. They are available with dynamic or OSSD signal Magne 4 is available in a choice of different variants.
These include an M12 8-pole connector, which permits information connectors for indication (e.g. when the anchor
plate is locked to the electromagnet). The 5-pole variant has a connector configuration that enables connection to a
Urax B1R adaptor unit for connection to the AS-i-bus.
Two variants of the Magne anchor plate are available. The one coded with a B has an inbuilt permanent magnet,
which holds the door or cover closed with a force of approx. 30 N when the power to the electromagnet is cut.
Magne 3 and 4 are supplied without an anchor plate and Magne 4 is also supplied without Eva (Eva is the passive
part of the non contact sensor that is integrated in Magne 4).
For further details, see chapter Overview of models.
Y-connectors can be used to connect several Magne units and Eden sensors in series, which enables control and
monitoring with one single Pluto safety PLC or Vital safety module
No current spikes over the rated current when locking is activated, which simplifies dimensioning of the system.
