Speed sensor

The E40H series hollow shaft type incremental rotary encoders feature Ø40 mm size housings and can be easily installed in tight or limited spaces. The low moment of inertia of the shaft minimizes the effect on the rotation of applied equipment. The encoders are available in various control output options.

Product Introduction

Introduction

By detecting and measuring the magnetic field variations generated by rotating gears or magnetic steels, the sensor achieves both speed measurement and direction detection. This type of sensor offers high reliability and excellent stability, and is widely used in motors and speed-detection equipment, such as low-speed passenger vehicles, sightseeing vehicles, aerial work platforms, forklifts, and other special-purpose vehicles.

● Dual-channel pulse signal output with 90-degree phase difference to detect rotation speed and direction.

● Built-in polarity and short-circuit protection.

● Wide temperature operating range.

● Good EMC anti-interference ability.

● High IP rating: IP67.

● Mainly used in electric sightseeing cars, electric golf carts, electric forklifts and other fields.

FAQ

Q: What does a wheel sensor do?

A: Wheel speed sensors, often referred to as ABS sensors, are small devices located at each wheel's hub or brake assembly. Their primary function is to monitor the rotational speed of each wheel and transmit this data to the vehicle's onboard computer system.

Q: Are wheel sensors hard to replace?

A: Replacing an wheel sensor is not a difficult task, but it's one that should be left to a professional. They'll have the tools and knowledge necessary to do the job right.

Q: How long does it take to fix a wheel sensor?

A: Fortunately, it is easy to replace a wheel speed sensor and takes you about an hour at maximum.
