Concept
The Lasermet IS-MDC-12 is a dual channel coded magnetic door safety contact. It is ideal for use in
conjunction with Lasermet’s ICS range of laser interlock controllers as part of a safety interlock
system.
It is used to detect when a door or other moveable cover forming part of a protective enclosure is
open. The IS-MDC-12 features three contacts, two of which are closed and one of which is open
when the door is closed. All three contacts change over when the door is open.
The IS-MDC-12 can achieve Performance Level ‘e’ as specified in EN ISO 13849-1:2015 when
correctly wired to a suitable interlock controller such as Lasermet’s ICS-6.

Summary of Evaluation of Compliance to EN ISO 13849-1:2015
To achieve a complete system performance level ‘e’ the system must be wired as described in this
manual using suitably rated door sensors and measures taken to minimise the effects of common
cause failures in the sensors and wiring which may be connected to the unit.

The level of performance assessed is based on the typical application demand resulting from the B10d values of the
internal components based on a maximum usage rate of 2920 operations per year.
