Compact purged actuators		• Hazardous Duty Edge Detectors — Stahl Intrinspak® safety barriers limit the amount of electrical energy that can flow into the hazardous environment through the edge detector cables. Energy is limited to a safe level that cannot ignite flammable gas, dust, or vapor mixtures.
Intrinsically-safe dynamically compensated edge detectors		• Hazardous Duty Purged Actuators — The purge system continuously circulates clean air through the actuator housing and cable. Positive pressure prevents the accumulation of flammable or combustible mixtures around the actuator motor and cable wiring. A separate return duct and pressure sensor continuously monitor airflow and shut off actuator power in the event of a leak. • Hazardous Duty Explosion-Proof Actuators — These actuators use explosion-proof motors to safely contain accidental combustion of gases or vapors within the motor housing. Available with a brushed DC motor or a high-performance brushless AC motor.
Powerful, explosion-proof actuators		• Accuracy and Reliability — Dynamically compensated edge detectors continuously adapt to changing environmental conditions and build-up of contaminants on the sensors. Eliminates maintenance headaches caused by constant cleaning and recalibration.
Powerful, explosion-proof actuators		• Operator Friendly — Intuitive operator interface with touch pad and LED indicators. The system configuration keypad is located inside the system enclosure, safe from inadvertent adjustments.
Purged AccuBeam II digital line guide available		• Network Friendly — Optional fieldbus adapters easily interface with most popular fieldbus networks, including ControlNet™, DeviceNet™, Modbus Plus, Profibus®-DP, and Ethernet protocols. Discrete I/O interfacing is a standard feature.
