Full titles differ between systems:

IPC:

Structural association of dynamo-electric machines with electric components or with devices for shielding, monitoring or protection > for measuring, monitoring, testing, protecting or switching > Devices for sensing speed or position, or actuated thereby > Optical devices

CPC:

Structural association of dynamo-electric machines with electric components or with devices for shielding, monitoring or protection (casings, enclosures or supports H02K5/00) > for measuring, monitoring, testing, protecting or switching (rectifiers H02K11/04; power electronics H02K11/33) > Devices for sensing speed or position, or actuated thereby (specially adapted for machines having non-mechanical commutating devices H02K29/06, H02K29/14) > Optical devices
