This document introduces the shape and size, technical parameters, general description, installation methods, environmental conditions, mechanical characteristics, general information, and ATEX 1G certification for Pepperl+Fuchs' capacitive sensor CJ1-12GK-N-15M. The sensor features non-level installation, NAMUR output polarity, 8V rated voltage, 0.1Hz switching frequency, etc.
The CJ1-12GK-N-15M is a capacitor‑type sensor designed for use in ATEX‑rated hazardous zones (1G, 2G, 1D). It complies with IEC and DIN standards, offers IP68 protection, and is suitable for environments with gases, steam, or fine mist. The document outlines the sensor’s mechanical and electrical characteristics, including mounting type, voltage range, and safety classifications.
The guide covers installation procedures, wiring polarity, adjustment, maintenance, and special conditions such as mechanical protection and electrostatic discharge. It also provides the required certification symbols (CE, Ex‑rating) and references to relevant standards (EN 60079 series, IEC 60947‑5‑2). Users are instructed to follow the technical parameters table and adhere to the safety limits for temperature and cable length. This manual is written in Chinese.
