Banner Engineering SI-LM40RC18D Photoelectric Sensor

The Banner Engineering SI-LM40RC18D is a metal-housed safety limit switch in Banner’s SI-LM40 family, identified by part number 93041. It uses a rod actuator with a roller to detect guard movement in industrial guarding systems and to relay a safe-interlock signal to the control circuit. This model is designed for guard interlock and machine-safety applications where reliable guard monitoring is required during access or closure of safety gates, doors, or other guarded points. As part of Banner’s SI-LM40 series, the RC18D variant integrates with Banner safety switching solutions and is commonly used on equipment such as conveyors and packaging lines to ensure stoppage when a guarded access is opened.
