Technical Questions Answered

• What types of targets work with this sensor?
• The sensor detects magnetic soft iron or regular steel targets best. Avoid using stainless steel as it won't trigger properly.
• How close should I mount the sensor to the target?
• Keep a 1mm air gap for Module 1 gears, or 1.5mm for larger Module 2+ gears. This ensures reliable signal detection every time.
• Can this sensor handle high-speed applications?
• Yes, it tracks speeds up to 720,000 counts per minute (12 kHz), making it suitable for most turbomachinery and rotating equipment.
• What's the sensor's protection against water and dust?
• The IP67 rating means it's completely dust-tight and can withstand immersion in water up to 1 meter deep for 30 minutes.
• How do I verify the sensor is working correctly?
• Check for proper voltage output - it should switch between >10V (high) and <1V (low) as each gear tooth passes the sensor face.
