Initiator cables, also referred to as sensor/actuator cables, connect control units and different sensors, or, in the case of reversal of the measurement principle, actuators. Frequently used abbreviations include ini or ini cable (plural: inis).
Sensor or measurement transducers transform physical quantities such as rotation, speed, distance or length into analogue electric impulses. In the case of an actuator, the measured electric current (symbol: I, unit: ampere; A) or voltage (symbol: U, unit: volt; V) is transformed into temperature, pressure or torque.
The connection cable consists of at least three cores with a small cross-section of between 0.14mm² and 0.34mm². In the simplest case, two cores are required for supplying the voltage, while the last core transmits an I/O signal. For sensitive applications, there are shielded versions in addition to the traditional ini cables to avoid EMC disruptions (electromagnetic compatibility).
Sensor/actuator cables for energy chains are cables for bend radii from 4xd. The CF.INI cables are tested in e-chains® with many millions of cycles. They have various approvals and conformities, e.g. UL, CSA, CE Desina and oil-resistance. Diverse cable ends are available for the sensor/actuator cable.
