AI-TEK 70085-1010-220 Speed Sensor 40V Output Magnetic Tachometer

Description Product Overview AI-TEK 70085-1010-220 is a robust speed sensor for industrial use. It delivers reliable speed readings in harsh environments. This sensor works with most standard speed monitoring systems. Key Features at a Glance High output voltage: 40V (P-P) standard, 12.8V (P-P) guaranteed minimum Wide temperature range: -55°C to 107°C for extreme conditions Low DC resistance: 130 ohms max for stable signals Compact size: 3.06 inches total length, 2.937 inches thread and sensor length Strong thread: 5/8 – 18 UNF for secure mounting Wire termination for easy connection Technical Specifications Brand: AI-TEK Model: 70085-1010-220 Series: 70085 Series Module Type: Passive Magnetic Speed Sensor Measurement Range: 0 to 20,000 Hz (typical) Frequency Response: 200 Hz to 15 kHz ±10% Sensitivity: 40V (P-P) standard at 1 kHz Linearity: ±1% over full range Resolution: 0.5% of full scale Temperature Range: -55°C to 107°C Environmental Protection: IP67 rated for dust and water Noise Immunity: Excellent against EMI/RFI DC Resistance: 130 ohms maximum Output Voltage (P-P): 40V standard / 12.8V guaranteed Termination: 2-wire shielded cable, 24 AWG Thread Size: 5/8 – 18 UNF, length 2.937 inches Sensor Body Length: 2.937 inches Total Length: 3.06 inches Shipping Weight: 2.1 kg Agency Approval: None (general industrial use) Installation Guide Clean the mounting hole before installation. Apply anti-seize lubricant on the 5/8-18 UNF thread. Hand-tighten then use a wrench for final 1/4 turn. Gap setting: 0.005 to 0.015 inches from gear tooth. Keep wires away from high voltage cables. Debugging & Maintenance Check output voltage with an oscilloscope. Verify DC resistance between 130 ohms max. Clean sensor tip gently with a soft cloth. No calibration needed for life. Quick disconnect wire harness available (sold separately). Compatibility Works with AI-TEK tachometers and PLCs. Compatible with most industrial controllers (5-30V input). Replaces obsolete models: 70085-1010-XXX series. Typical Applications Conveyor belt speed monitoring Gear tooth detection in motors Pump shaft speed feedback Wind turbine generator speed Mining equipment drivetrain Diagnostic Capability Detects missing pulses from damaged gears. Self-diagnosis: open circuit or short detection. Low output alerts possible with external comparator.

Frequently Asked Questions (FAQ) What is the minimum target speed? About 5 RPM with a 60-tooth gear. Output drops below 200 Hz. Can I use this sensor in water? No. IP67 is for temporary immersion only. Why is my output voltage low? Check the air gap. Reduce to 0.010 inches max. Does it work with stainless steel gears? Yes, but output drops 20%. Use ferrous gears for best result. How to choose between this and 70085-1010-210? The 220 version has longer thread (2.937 vs 1.5 inches). Pick 220 for thick mounting brackets. My sensor gets hot at 100°C. Is that normal? Yes. Up to 107°C is safe. Above that, replace it. Can I cut and extend the wires? Yes. Use shielded cable and keep total length under 30 meters. Selection Guide Need shorter thread? Choose 70085-1010-210 (1.5 inch). Need higher temperature? Choose 70085-1010-250 (150°C max). Need explosion proof? This model has no ATEX rating. Look for 70085-EX series. For very low speed ( Contact & Support For technical help or bulk pricing: 86 158 8020 0923 (WhatsApp) Copyright © 2026 PLCDCS HUB Limited. All rights reserved.
