FAQ: Circular Connectors & Cables – Selection & Application Guide

Q1: What are circular connectors used for?

Circular connectors are cylindrical, multi‑pin electrical connectors designed for rugged, reliable power/signal transmission in industrial environments. Common uses:

Industrial automation (sensors, actuators, PLCs)

Robotics & machine vision
Medical equipment
Rail & transportation
Renewable energy (solar/wind)
Marine & outdoor lighting

Q2: What’s the difference between M8, M12, and M23 circular connectors?

M8: Ø8mm, 3–8 pins, compact, for low‑power sensors.
M12: Ø12mm, 3–17 pins, most common in automation; A‑code (signal), B‑code (fieldbus), D‑code (Ethernet).
M23: Ø23mm, 6–24 pins, higher current, for motor/power connections.

Q3: IP67 vs IP68 – which do I need?

IP67: Dust‑tight, protected against temporary immersion (1m/30min) → outdoor, general industrial.
IP68: Dust‑tight, protected against continuous immersion → washdown, marine, harsh outdoor.

Q4: Can Torven provide custom cable assemblies?

Yes. Torven offers:

Custom pinouts & wire gauges
Overmolded or crimped connections
Shielded/unshielded cables
High‑flex/drag‑chain cables
OEM/ODM branding
