3. Length version distinction Table
Model suffix Cable length Material number
C5 5 meters 933237100-5
C7 7 meters 933237100-7 (This model)
C10 10 meters 933237100-10
4. Differences in R suffix versions
R1: Basic single shielded cable
R2: Double-layer overall shielding + split-core shielding, specially designed for strong electromagnetic interference scenarios (power plants, refining and chemical plant frequency converter cabinets), with stronger anti-interference performance
Four. Logical assembly usage
F3237 module is inserted into the HIQuad safety rack;
Z7108 plug is inserted into the rear interface of the module;
7-meter pre-extended cable is extended to the on-site terminal cabinet, and the loose wire end is connected to the on-site switch / proximity sensor;
The module has dual-channel collection inside, the cable is fully shielded to suppress interference, and meets the SIL3 safety circuit wiring specification.
