Product Introduction

This Ø6.5mm Miniature Inductive Sensor is a specialized high-performance component designed for precision automation in confined spaces. Unlike standard threaded sensors, this model features a Ø6.5mm smooth cylindrical housing, making it ideal for mounting via set screws or clamp fixtures in compact machinery, grippers, or robotic arms.

Despite its diminutive size, the sensor delivers an impressive 4.0mm sensing range (Non-flush), allowing for reliable detection of small parts without requiring the sensor to be positioned dangerously close to the target. It is constructed from high-grade Stainless Steel, providing exceptional structural integrity and protection against corrosion in harsh industrial environments.

Performance-wise, the sensor excels with a high switching frequency of 2 kHz, making it perfectly suited for high-speed applications such as rotational speed monitoring or small part counting. Electrically, it utilizes a convenient DC 2-Wire Normally Closed (NC) configuration, simplifying wiring integration. With an IP67 protection rating and wide operating temperature range (-25°C to +75°C), this miniature sensor offers a robust, space-saving solution for critical positioning tasks.
