Technical Overview

The Omron E32-C91N 2M is a professional-grade standard fiber optic sensor head designed for precise diffuse reflective sensing. Engineered with an M6 threaded cylindrical body and a hexagonal back, it features a 90-degree right-angled cable exit for easy integration into tightly constrained spaces. The sensor utilizes a highly flexible 2-meter plastic fiber with a durable polyethylene sheath and a minimum bending radius of R4 mm. Rated IP67 for protection against harsh industrial environments, it operates reliably across a wide temperature range of -40 to 70°C. When paired with advanced amplifier units like the E3NX-FA series in Giga mode, it can achieve a sensing distance of up to 1170 mm.

Key Features

  • Diffuse reflective sensing method for reliable object detection
  • 90° right-angled cable exit with hexagonal back for tight-space mounting
