Overview
The Eaton E65-SMPP050-HDD is a compact photoelectric sensor from the Perfect Prox SM Series engineered for industrial automation, machine vision, and process control applications. This model features background suppression detection with dark operate (dark-on) output logic, making it ideal for applications where the target is darker than the surrounding environment. The sensor operates on 10–30 VDC and includes a quick-disconnect (QD) connector with 4-pin configuration for field-proven reliability.
Key Features
- 50 mm sensing range: Delivers accurate detection at short to medium distances in compact spaces
- Dark operate output: Sensor triggers when target is absent or blocks the light beam
- TargetLock technology: Built-in alignment indicators provide visual feedback and diagnostic information to prevent misalignment and equipment downtime
- Visible red sensing beam: Allows operators to pinpoint exact sensor aim and verify target positioning
- Quick-disconnect connector: 4-pin configuration simplifies installation, replacement, and field service
- Robust environmental rating: NEMA 1, 3, 4, 4X, 6, 6P, 12, 13 and IP68/IP69K enclosure protection for wet, dusty, and wash-down environments
