Sensor Connectors Component – Computer, Electronic and Optical Product Manufacturing

Q: What are the most common types of sensor connectors?

M12 and M8 circular connectors are most common, with 3-8 pins for different sensor types. M12 connectors dominate industrial automation with coding options (A-coded for sensors, B-coded for fieldbus).

Q: How do I choose between IP67 and IP68 rated connectors?

IP67 connectors withstand temporary immersion (1m/30min) while IP68 handles continuous immersion (specified depth/time). Choose IP68 for washdown areas or submerged applications.

Q: Can sensor connectors be used in explosive atmospheres?

Yes, with appropriate certifications (ATEX, IECEx) and increased safety designs that prevent sparking through proper sealing and contact protection.

Component Specifications

Definition

Sensor connectors are specialized electromechanical interfaces designed to establish secure, low-resistance electrical connections between various types of industrial sensors (temperature, pressure, proximity, etc.) and the sensor interface board or control system. These connectors ensure accurate signal transmission while protecting against environmental factors like moisture, vibration, and electromagnetic interference in industrial settings.

Working Principle

Sensor connectors operate by establishing physical and electrical contact between sensor leads and interface board terminals through mating pin/socket arrangements. They maintain signal integrity through precision contact geometry, proper insulation, and shielding mechanisms that prevent signal degradation, cross-talk, or interruption in harsh industrial environments.

Materials

Contacts: Phosphor bronze or beryllium copper with gold/nickel plating; Housing: Thermoplastic (PBT, PA66, PPS) with UL94 V-0 flame rating; Seals: Silicone rubber (IP67/IP68 rated); Shielding: Nickel-plated steel or aluminum.
