Wenglor OHD202A0103 Reflex Sensor Background Suppression

Description

The Wenglor OHD202A0103 Reflex Sensor with Background Suppression works on the principle of angle measurement, allowing it to detect objects based on their geometric position rather than reflected light intensity. This advanced method ensures that the sensor ignores backgrounds effectively, making it perfect for detecting dark objects against light-colored or reflective backgrounds without losing accuracy.

This sensor is designed for seamless digital integration. With IO-Link 1.1, operators can access real-time distance data and comprehensive condition monitoring statistics to prevent unplanned downtime. The sensor supports multiple switching outputs (PNP, NPN, or Push-Pull) and operates at a high switching frequency of 1,000 Hz. Built to last, the unit is encased in a robust plastic housing with IP67/IP68 protection, ensuring stable performance even in environments exposed to moisture, dust, and temperature fluctuations.
