Coil with 12000 turns

Laboratory coils
Coils encased in transparent high-impact plastic, capable of sustaining heavy loads,
connection by way of 4-mm safety jacks, embedded in coloured lids, which prevent bodily contact,
individual specifications such as number of turns, direction of the winding, effective resistance, inductivity and the maximum continuous current are given on the coil,
a full-length opening (31x31) allows mounting on u-shaped cores or insertion of iron cores

Transparent plastic case prevents contact with the coil winding;
max. current: 100 mA; effective resistance: 1 kOhm;
inductivity: 4 H
Effective resistance: 2 kOhms, inductivity: 4 H
