3.6 Magnet contact sensor
STM 550 integrates a magnet contact sensor detecting presence or absence of a magnetic
field in the proximity of the it. Refer to Figure 13 and Figure 14 for the location of the mag-
net contact sensor within STM 550 and to chapter 11.5 for mounting instructions.
EMSI product packaging includes a block magnet suitable for use with its magnet contact
sensor. Figure 12 shows the outer appearance of this magnet.
