The Omron E32-R21 2M is a compact retro-reflective fiber optic sensor head with an M6 cylindrical axial design. It includes the E39-R3 reflector and uses R25 fiber, enabling accurate detection of transparent and small objects at distances up to 370 mm.
This sensor features a 2-meter polyethylene cable and a threaded body for easy mounting in tight industrial setups. Its axial configuration supports direct alignment with reflectors, simplifying system design in packaging, labeling, and glass detection tasks. The small bending radius allows flexible installation even in restricted spaces.
The sensor housing is built from durable plastic and is rated IP67, making it suitable for environments exposed to dust or water. Operating within a wide temperature range of 40Β°C to 70Β°C, the E32-R21 is a reliable choice for high-precision industrial sensing where robustness and detection clarity are essential.
