Depending on the version requested, “item no. suffix . . . /010-000” is added to the “basic item no.”
MCS — MULTI CONNECTION SYSTEM includes connectors without breaking capacity in accordance with
DIN EN 61984.
When used as intended, these connectors shall not be connected/disconnected when live or under load. The circuit
design should ensure header pins, which can be touched, are not live when unmated.
