Overview
The Banner SM31R Mini-Beam photoelectric receiver sensor is a self-contained opposed-mode modulated infrared receiver for industrial automation and motion control. The Mini-Beam-DC-Voltage Series offers self-contained opposed mode modulated Infrared Sensor pairs for 10 to 30 V dc operations. This receiver pairs with a Banner transmitter to create a through-beam photoelectric system for detecting objects across its 3-meter sensing range.
Key Features
- Receiver with 3 m range, 10-30 V dc input, and bipolar 1 NPN / 1 PNP output
- Exclusive Alignment Indicating Device system (AIDâ„¢) lights a rear-panel mounted red LED indicator whenever the sensor sees a “light” condition
- Bipolar configuration with one current sourcing (PNP) and one current sinking (NPN) open-collector transistor output
- IP67 rated for harsh industrial environments with infrared LED light source
- Switch-selectable for light operate or dark operate modes
- 2 m (6.5 ft) cable connection included
