Overview
The Cutler-Hammer E65-SMTD15-HD is a thru-beam photoelectric sensor receiver from Eaton’s compact SM Series. Designed for industrial detection and automation control applications, this receiver unit operates across 15-meter sensing distances and pairs with a compatible transmitter to detect the presence or absence of objects on assembly lines, conveyor systems, and process equipment. The dark-operate (normally-off) configuration activates output when the beam is blocked, making it ideal for object detection and counting applications.
Key Features
- 15-meter sensing range: Supports long-distance thru-beam detection for wide machinery and conveyor applications
- TargetLock™ LED indicators: Visual confirmation of proper sensor alignment and diagnostic feedback to prevent downtime
- Dual output modes: NPN and PNP open collector outputs accommodate both sinking and sourcing circuit designs
- Durable compact housing: Rectangular body with multiple mounting options for tight installation spaces
- Cable connection: 2-meter DC cable with connector interface
- Industrial certifications: UL, CSA, and CE approved for North American and European deployments
