Relationship between life & load
Temperature Power Sensor, TPS can perform more than 2 million
mechanical operations. However, under heavy loads, the life will
be reduced due to the wear of contacts. A life of 100,000 cycles of
operation is guaranteed at the rated load current. Under reduced
loads, the life lasts longer. See the graph to the right.
Contact type indication
? Contacts which open when the temperature rises are designated as X, and those which close
when the temperature rises are designated as Y. Shown in the diagram is the temperature at
which the contacts operate when the temperature rises (the high temperature side).
? X [Xbar] and Y [Ybar] are used for contacts that operate when the temperature falls (the low
temperature side). X [Xbar] indicates the contact that closes when the temperature falls. Y
[Ybar] indicates the contact that opens when the temperature falls. Z indicates transfer con-
tacts. XZ is the main contact that opens when the temperature rises. XZ [Xbar Z] is the main
contact that closes when the temperature falls.
? C is the standard rank designation for X contacts and B is standard for Y contacts. Please
consider X is C ranked and Y is B ranked, unless otherwise indicated.
Model designation method

For 5 Amp. Series with a back contact, a model name will be, for example, M3
70XZB, where Z means contact with the back contact.
