Absolute rotary encoders
The Hengstler Acuro series absolute rotary encoders combine innovative engineering technology, ease of use and optimal functionality. The platform concept makes it possible to make the devices as compact as possible and provides ample opportunities for creating internal modular systems. With this comprehensive modular system, it is easy to find the most suitable option for all applications, including motor communication and automation. Equipped with an open BiSS interface, Hengstler's absolute rotary encoders are fully up-to-date and ready for future developments.
Incremental Rotary Encoders
Hengstler's range of incremental rotary encoders includes both standard budget models and extremely high performance products designed for heavy duty applications. Optical incremental encoders have a linear code disc made of metal, glass or plastic, which is mounted on a rotary bearing and blocks the light beam emitted by the LED. Resolution, i.e. the number of measured points per revolution is determined by the number of lines. The interruption of the light beam is recorded and processed by an electronic receiver, then the information is transmitted as a rectangular signal to the output of the encoder. Hengstler manufactures incremental encoders up to 10,000 pulses per revolution.
Rotary Sin / Cos encoders
Hengstler's precision rotary sine wave encoders are most effective for highly dynamic drive applications due to their low harmonic distortion of sine waves. They have excellent immunity to interference, error compensation and high functional dependency, as well as control and monitoring capabilities of systems. The wide operating temperature range allows the engine power to be used as efficiently as possible. Channel width up to 500 kHz with high signal quality.
Hengstler multifunctional counters are represented by various types of counters, tachometers, timers, offset counters, sectional counters with basic functionality. Combined with a wide range of individually programmable options, these devices can be easily adapted to suit any real customer need and task. There are manual and electronic zeroing of the counter values and various types of mounting (PCB, DIN-rail, surface mounting and front panel mounting), some of which have a built-in display.
The Hengstler preset counters are counters with controller functions. The range includes various models suitable for solving a variety of tasks. The type of meter signal (electronic, electromechanical, pneumatic or mechanical) depends on the requirements. Many preset counter models have two preset programs, one of which has a built-in pre-shutdown function that can be used to gradually reduce speed or change the degree of accuracy. Examples of practical applications include monitoring windings or measuring the consumption of strictly metered components. Monitoring of windings or metering of the consumption of strictly metered components can be carried out.
Hengstler cumulative counters are used to record the number of events and display the result digitally in numerical form. The main characteristics of Hengstler's wide range of totalizing counters, like any other product manufactured by this company, are the use of the most modern technologies, attractive and ergonomic design, high quality and reliability in operation. Such counters can be used, for example, when counting the number of units produced and recording consumption volumes.
Hengstler time counters display the running hours of plants, machines and devices, providing information on the remaining time until the warranty expires, hours of operation and time until the next scheduled maintenance. The time counters are also available on request in various configurations with a modern, attractive design. Typical applications for Hengstler timers include tracking the time between scheduled maintenance intervals and controlling the addition of ingredients to be mixed.
The problem of isolating high switching loads has always been very acute since the invention of the relay. In addition, there are regulatory requirements for current leakage at the insulator surface and safety distances, which makes the solution of such problems subject only to manufacturers with many years of experience in the development and manufacture of relays. Hengstler has this experience and implements it in its isolation relays to ensure the maximum degree of electrical safety for machines and people.
High voltage relays
With over 50 years of experience in high voltage relay manufacturing, Hengstler offers a variety of relay options and models to suit a wide variety of applications and requirements. The rated voltage of Hengstler relays ranges from ≤12 V to> 230 V. The relays can have 0 or 1 NO contact or 0/1 NO contact and are equipped with reinforced insulation. Depending on the specific model, Hengstler high voltage relays can be operated at ambient temperatures from -25C to + 70C.
For decades, Hengstler has been intensively developing mechanically interlocked or bonded contacts. As a result of the work done, Hengstler safety relays were created. Numerous customers of the company all over the world can now take full advantage of this type of relay, created as a result of years of work, in the development and production of relays with mechanically interlocked contacts. The safety relays are available with standard or reinforced insulation. The rated voltage of Hengstler safety relays ranges from ≤12 V to> 230 V.
Hengstler tachometers are designed to record events that occur over a sequence of time, and are commonly used to record information about product exit rate, rotational speed, throughflow and other quantities. The measurement is carried out at the output or according to the more accurate principle of the period length by means of preliminary programming of the necessary parameters, which allows the system to be adapted to work in different measurements. Hengstler tachometers are often used to display and monitor rotational speed or the actual speed of equipment.
Hengstler brushless resolvers are ideal rotor position indicators and position feedback for brushless motors, robots or direct drives Hengstler resolvers are powerful and reliable, and are also suitable for high operating temperatures (up to 155 ° C) and are robust most types of liquids used in technological processes, various contaminants, many types of radiation and electromagnetic interference. In addition, Hengstler brushless resolvers are highly resistant to shock and vibration.
Hengstler proximity switches do not require physical contact and are activated due to the magnetic field or ferromagnetic properties of the object. The device does not require continuous air supply for correct operation. Hengstler proximity switches have a very compact size, which allows them to be used even in the most space-constrained spaces. Like all Hengstler products, proximity switches are of the highest quality and reliability and have a long service life.
Hengstler's line of position indicators are modern in design and include counters, tachometers and timers. Even the smallest models in the series are equipped with an easy-to-read display with two display options (8-digit liquid crystal display or 6-digit LED display). The position indicators operate from an input voltage of 12 to 24 volts DC or from an independent power source in the form of a lithium battery. The counting frequency and triggering slope of the signal can be programmed depending on the specific application. The high voltage versions operate with pulses between 12 and 250 volts dc or ac.
After printing, it is often necessary to cut straight off the printout, receipt or other data carrier. Hengstler offers a wide range of powerful and highly reliable cutters in various cutting widths. Hengstler cutters are maintenance-free and self-sharpening. Thanks to its extensive experience in this field, the company has managed to become the largest manufacturer of cutters in Europe. Hengstler cutters ensure perfect cut and maintain functionality in a wide range of climates from Alaska to the Caribbean.
Since 1965, Hengstler has been supplying printers and cutters to the world market. Over time, the company's specialization has become built-in thermal direct printers.
