elevator encoder

If you are looking for a high-quality elevator encoder, Industrial Encoder Corporation is the leading supplier. Its magnetic and optical encoders are designed for industrial applications, such as elevators. IEC has installed over 20,000 encoders in elevators over the past 10 years. In this article, you will learn about the advantages and disadvantages of each type. Once you have chosen the correct encoder for your elevator, you will be much safer and more efficient in your workplace.

AH800 rotary encoder

The AH800 rotary elevator encoder is a powerful tool for measuring the angle of an elevator. The encoder measures the angle by displaying it in 3-bit binary-reflected Gray code. The inner ring corresponds to Contact 1 in the table. In addition, the black sectors represent “on” and zero degrees correspond to the right side. As the elevator rotates, the angle increases in the opposite direction. This type of encoder is marked with a unique code, which means that two adjacent codes are different by one bit.

This rotary elevator encoder is designed to provide feedback to monitor automatic doors in elevator cars. The doors are operated by a mechanism driven by a small motor mounted at the top of the elevator car. The encoder monitors the operation of these motors to ensure that the doors open and close completely. This requires a hollow-bore design, a high-resolution signal, and high-quality protection.

The AH800 rotary elevator encoder has a shaft diameter of 20mm and an outer diameter of 80mm. The encoder can be installed directly onto the B-Side of an elevator motor, without any mounting holes. The AH800 has a clamp to prevent rotation of the encoder housing. It also features 13-bit absolute resolution and SSI Protocol, which make it the ideal choice for elevators.

CB62 incremental encoder

The ASB62 absolute rotary encoder and CB62 incremental elevator encoder are designed specifically for use in servo and gearless motors. They both provide accurate position and speed feedback and offer low profile designs and easy installation. The CB62 incremental encoder features an extended operating temperature range of -4degF to 212degC. The encoders have an IP40 protection rating and are suitable for applications in robotics and automation systems.

When choosing an incremental elevator encoder, signal quality is a critical factor. Its signal must be well-behaved square-wave pulses with 50-percent duty cycles. Furthermore, the elevator environment involves high-power cables and inductive loads. The encoder wiring must be separated from the power wires and installed in twisted-pair shielded cabling. If the incremental elevator encoder is installed on an elevator that is subject to high levels of vibration, it must have a programmable, reversible switch.

Elevator encoders provide feedback to the elevator control system. They ensure mechanical and passenger safety by monitoring elevator doors. Unlike conventional elevator switches, an incremental elevator encoder delivers feedback information to the elevator control system to make sure the doors are fully opened and closed. Ultimately, these devices ensure the smooth operation of elevators and improve the quality of life for all passengers. A Dynapar incremental elevator encoder offers reliability and excellent reliability.

LINA 200 absolute linear encoder

A cableless elevator can make use of a LINA 200 absolute linear encoder. These high-performance sensors use two separate tracks with different signal periods to determine the total position value. Because the two tracks are located on different planes, the encoder can scan a measuring standard from both sides. This feature enables it to provide fast, accurate readings while maintaining a low weight. Consequently, the LINA 200 absolute linear elevator encoder is ideal for applications that require high speed and/or long life.

An absolute linear encoder is an efficient way to determine a load’s position. It generates a unique digital word that describes where the load is. The resolution is measured in bits per revolution, which is easy to measure. Single turn and multiturn devices have different resolutions. An encoder with a 14-bit resolution can measure up to 16,384 discrete positions per 360-degree revolution. Moreover, it can communicate the exact position to a controller using a serial link.

The LINA 200 absolute linear elevator encoder can measure the position of a loading gantry without the need for manual positioning. The encoder’s position values are calculated according to a manufacturer’s convention. However, it is important to remember that absolute encoders can have incorrect position values. This can result in a motor drawing excessive current and not turning at all. To avoid such a problem, you should select an encoder with an A-B feedback. Absolute encoders typically use two channels: the A channel and the B channel.

It is used in a wide range of systems, laboratory devices, and medical devices. It is a low-cost alternative to other types of encoders.

Its compact design allows it to fit in any location. The HTx36 elevator encoder is made of high-quality components, ensuring accurate measurements. Its signal is square-wave pulses with 50 percent duty cycle. Because the elevator environment is made of high-power cables and inductive loads, the encoder wiring should be shielded to prevent the encoder signal from causing any interference. This is especially important if it will be installed on a long shaft.

They are available in a variety of shaft diameters and are also suitable for applications in confined spaces.

Encoders are essential in elevator operations. A separate assembly from the motor feedback, the governor controls elevator speed. Encoder feedback detects the car speed if it exceeds a preset threshold, triggering the safety mechanism. High-resolution direct reads may be required to ensure elevator safety. High-resolution direct read resolutions can be required, such as 10,000 PPR. If you have a high-speed elevator, an incremental encoder is a more cost-effective option.
