Component Specifications

Definition
A conduit entry is a critical component in industrial sensor systems, specifically designed for the Sensor Connection Head. It serves as an interface point where electrical conduits or cable glands attach to provide a secure, sealed entry for sensor wiring. This component ensures environmental protection (against dust, moisture, chemicals) while maintaining proper strain relief and electrical continuity. It typically features threaded connections compatible with standard conduit sizes and may include sealing elements like gaskets or O-rings.
Working Principle
The conduit entry operates on mechanical sealing and strain relief principles. It uses threaded connections to secure conduit pipes or cable glands, while integrated seals (rubber gaskets, compression fittings) create a barrier against external contaminants. The design distributes mechanical stress from cables/conduits to prevent damage to internal sensor connections, maintaining signal integrity in harsh industrial environments.
Materials
Typically manufactured from corrosion-resistant materials: stainless steel (AISI 304/316), brass, aluminum alloys, or engineered plastics (PA, PBT) with IP67/IP68 rated sealing elements (EPDM, NBR, silicone rubber).
Technical Parameters
  • IP Rating IP67/IP68
  • Thread Size M12 to M40 metric or NPT 1/4" to 1"
  • Material Grade 316 Stainless Steel
  • Temperature Range -40°C to +120°C
  • Cable Diameter Range 3mm to 25mm
Standards
ISO 7005-2, DIN 43650, IEC 60529
