Magnetic Pickup Speed Sensor for Gear/Hydraulic Pump

The SUCH magnetic pickup speed sensor is a non-contact, variable reluctance sensor that measures gear or shaft rotational speed by detecting flux changes as ferromagnetic teeth pass its magnetic field. Built into a rugged 5/8-18 UNF threaded steel body, it withstands oil, dust, and wide temperature swings typical of industrial settings. Common applications include gearboxes, hydraulic pumps and motors, and rotating machinery on vehicles and industrial equipment requiring reliable speed feedback.

Feature

• Non-contact measurement – Detects gear or shaft speed without physical contact, eliminating wear and extending service life
• Wide operating frequency range – 0–20 kHz output, suitable for both low-speed and high-speed rotating equipment
• Wide operating temperature range – Stable performance across demanding thermal environments
• High resistance to contamination – Unaffected by oil, dust, or other airborne debris at the measurement site
• Robust mechanical design – Sensing face rated to withstand up to 10 bar of pressure
• Standard threaded mounting – 5/8-18 UNF thread for straightforward installation and gap adjustment
• Strong signal repeatability – Consistent, accurate frequency output for precise speed feedback to control units

Installation

Note: Proper installation requires positioning the sensor tip directly opposite the target gear teeth, maintaining a defined air gap (per the gear tooth pitch and tooth height parameters) to ensure a stable, repeatable signal output. The sensing gap should be adjusted according to gear diameter (Do) and tooth width (F) to avoid signal loss or false triggering caused by excessive clearance.
