Connection Cable/Interface: Temperature Range -40°C to +105°C

Component Specifications

Definition

A specialized connection cable and interface system designed for high-resolution gap sensors, featuring multi-conductor shielded cables with precision connectors that maintain signal integrity in industrial environments. This component ensures reliable transmission of microvolt-level analog signals over distances up to 100 meters while providing EMI/RFI protection, mechanical strain relief, and environmental sealing.

Working Principle

The cable assembly utilizes twisted-pair conductors with individual foil shielding and overall braided shield to minimize electromagnetic interference. The interface connectors employ gold-plated contacts with spring-loaded mating mechanisms to ensure consistent electrical contact. Signal transmission follows differential analog principles where voltage variations corresponding to gap measurements are carried through dedicated conductor pairs while maintaining ground reference isolation.

Materials

Conductors: Oxygen-free copper (OFC) 22 AWG, 7-strand; Insulation: Fluorinated ethylene propylene (FEP) 0.5mm thickness; Shielding: Aluminum foil + tinned copper braid (85% coverage); Outer jacket: Polyurethane (PUR) oil-resistant; Connector housing: Glass-filled polyamide (PA66-GF30); Contacts: Beryllium copper with 0.5μm gold plating over 2.5μm nickel underplate.

Frequently Asked Questions

What is the maximum cable length for reliable signal transmission?

Maximum recommended length is 100 meters for analog signals up to 100 kHz. Beyond this distance, signal attenuation may exceed 3 dB, requiring signal conditioning or amplification.

Can this cable interface be used with different sensor brands?

Yes, when using standard M12 A-coded connectors with pin-to-pin compatibility. However, always verify voltage levels and pin assignments match the specific sensor manufacturer's requirements.

How does the shielding protect against interference?

Dual-layer shielding combines individual pair foil shielding with overall braided shield, providing >90 dB attenuation against both electric fields (foil) and magnetic fields (braid), with the drain wire ensuring proper grounding.
