B10d = > 2 x 106 operations at min.
PFHD = > 3 x 107
MTTFd = > 385 years
Dual channel interlock may be suitable
for Performance levels PLe or PLd
(according to ISO 13849-1:2006) and for
use in SIL2 or SIL3 systems (according
to IEC 62061) depending on application
characteristics
With the increasing speed and complexity of applications a simple
magnetic switch may be insufficient to meet the increased risks,
therefore the design incorporates several magnetically sensitive
elements which must be triggered in a particular sequence to
operate correctly.

The sensor with its molded-in brackets and diminutive size, is
extremely versatile and simple to install. For high-risk applications
the control unit is used with a single sensor to give a high-integrity
system. For other applications, multiple sensors (including
mechanical switches) can be connected.

Usable for ISO 13849-1:2006 and IEC 62061. Data other than B10d is
based on:
- Usage rate of 1op/10 mins., 24 hrs/day, 360 days/year, representing
51840 operations per year
- Mission time/Proof test interval of 38 years
! The safety contacts are described as normally closed (N.C.) i.e., with the
guard closed, actuator in place (where relevant) and the machine able to be
started.
