1.2.2.1.5 Battery for Multi-Turn
The battery for Multi-Turn must be placed separately, there is no dedicated space for it in Circulo. The pins
for the battery are incorporated into the
.
Note
Usually, all multi-turn encoders are connected to the same battery to facilitate potential replacement.
1.2.2.1.5.1 Suitable batteries
Primary cells with a nominal voltage of 3.3 V - 5,5 V are required as the battery voltage must always stay
above 3.0 V during operation. Such batteries are available for moderate as well as for extended temperature
range (e.g. 125 °C). Suitable cells are mainly based on lithium thionyl chloride (LiSOCL2). They feature high
energy density, high output voltage stability and operating life up to 25 years. The self-discharge per year is
typically in the range of 1 %.
