ifm Fail-Safe Inductive 18mm Barrel Proximity Sensor
Contact: 1-800-633-0405 | AutomationDirect.com
Safety technology is crucial for safe human-machine interaction and forms a key part of safety systems for personnel and machinery. Inductive sensors offer advantages in many safety applications, enabling direct detection of metal and helping system designers meet various design challenges. Their non-contact nature eliminates physical wear, and a high protection rating ensures high uptime for machines and installations. These fail-safe sensors do not require a magnet or coded target; they detect metals and operate with an enable zone monitored for target position and dwell time.
Features
- Certification to EN 60947-5-3 for electromechanical control gear
- No special actuator required for electronic fail-safe sensors
- Series connection of sensors is possible
- Standard 18mm barrel housing
- OSSD output
