• Activation level: 50 mm or 2 inches
• Deactivation level: 20 mm or 3/4 inch
• Delay: 3 second delay to reduce false starts
• Electrical rating: up to 20 amps at 12 or 24 volts
• Compatibility: Johnson Pump submersible pumps within the listed rating
• Construction: sealed solid state electronics and field detectors
• Sensor design: detector cells do not contact the water and are not affected by oil or foreign debris
• Additional features: no mercury and no exposed sensors
