Electrical Connector / Cable: Voltage Rating 30V DC max

Component Specifications

Definition

A specialized electrical connector and cable assembly designed specifically for pressure sensors and transducers, providing reliable electrical connections for signal transmission (typically 4-20mA, 0-10V, or digital protocols) and power supply (commonly 12-24V DC) in industrial environments. This component ensures accurate data transfer from the sensor to control systems while maintaining electrical integrity under varying pressure, temperature, and environmental conditions.

Working Principle

The electrical connector establishes secure mechanical and electrical contact between the pressure sensor's output terminals and the cable conductors. The cable transmits analog or digital electrical signals proportional to measured pressure values from the sensor to monitoring/control equipment. Proper impedance matching, shielding, and insulation prevent signal degradation, electromagnetic interference, and electrical leakage.

Materials

Connector housing: PBT, PA66, or stainless steel (IP67/IP68 rated); Contacts: Gold-plated copper alloy or phosphor bronze; Cable insulation: PVC, PUR, or FEP; Cable shielding: Aluminum foil and/or braided copper; Conductor: Tinned copper strands; Sealing: Silicone or fluorosilicone rubber gaskets.

Frequently Asked Questions

What is the difference between M12 and M8 connectors for pressure sensors?

M12 connectors (12mm thread) are standard for most industrial pressure sensors, offering more pins and higher current capacity. M8 connectors (8mm thread) are used for compact sensors where space is limited, typically with fewer pins and lower power requirements.

How do I choose between PVC, PUR, and FEP cable insulation?

PVC is economical for general industrial use; PUR offers excellent oil, chemical, and abrasion resistance; FEP provides superior temperature resistance (up to 200°C) and chemical resistance for extreme environments.

What maintenance do pressure sensor connectors require?

Regular inspection for corrosion, proper sealing integrity, and secure connections. Clean contacts with electrical contact cleaner if needed. Replace if IP rating is compromised or if physical damage occurs.
