Encoders - Rotary and Linear

Rotary and Linear encoders are a special type of transducer for measuring rotational position or linear distances.

There are two main areas of application for linear encoders:
Measurement
Measurement application include coordinate-measuring machines (CMM), laser scanners, calipers, gear measurement, tension testers, and digital read outs (DROs).

Motion systems
Servo controlled motion systems employ linear encoder so as to provide accurate, high-speed movement. Typical applications include robotics, machine tools, pick-and-place PCB assembly equipment; semiconductors handling and test equipment, wire bonders, printers and digital presses.

Rotary encoders are used in a wide range of applications that require monitoring or control, or both, of mechanical systems, including industrial controls, robotics, photographic lenses, computer input devices such as optomechanical mice and trackballs, controlled stress rheometers, and rotating radar platforms.

MasTec has the largest range of encoders in the industry from a range of suppliers.

  • Incremental Encoders - shaft and hollow shaft
  • Absolute Encoders - shaft and hollow shaft
  • Linear Encoders - Tape
  • Linear Encoders - Cable
  • + Encoder cables

This is another of the technologies that has grown so large that the edges are difficult to find these days.

In modern hospitals, there is an increasing need for digital healthcare to allow hospitals to improve workflows and patient experience. Medical grade computers and mobile devices that support patient monitoring, data transfer, and wireless transmission are becoming increasingly essential for providing streamlined patient care in clinical environments.

Medical-grade computers, monitors and mobile tablets to enable hospitals and clinical institutions to deliver the highest quality and optimum patient care in wide range of healthcare environments.

Some features specifically fundamental for the healthcare environment:

- High performance
- Sealed & Waterproof
- Fanless
- Protectiond from water and dust. Allowing thorough cleaning.
- Antimicrobial Housing, reduces the spread of germs.
- Meet Stringent Safety Standards
- 60601 Certified. Protects patients & hospital staff from electrical & radiation hazards.

Solid State Relays (SSRs)

MasTec has sold OPTO 22 SSRs since the mid 1990's - we stock in volume and sell in volume.

Opto 22 provides a full range of Power Series relays with a wide variety of voltage (110–575 volts) and current options (3–45 amps).
All Power Series relays feature 4,000 volts of optical isolation, and have a high PRV rating.

Where OPTO 22 products cannot provide a spec match and for some specialised situations we use Power-io, Crydom and other speciality companies.

OPTO 22 can switch up to 575 VAC at 45 amps in a standard hockey puck module. OPTO 22 is not so strong in DC switching and only have low current ranges. We do have other options.

If you are building machines and you need to control AC power, then hockey puck SSRs are excellent as they can be mounted directly to steel cases for heatsinks or if the current is low then use the PCB mount SSRs from OPTO 22.

For distributed SSRs use the OPTO 22 G1, G4 or SNAP products that are backplane mounted.

For DIN Rail SSRs, large SSRs with heatsinks, single and three phase and contactors plus motor starts use Power-io.

Thyristors and IGBT Controllers

Thyristor controllers are designed to control the battery heat of Heating Ventilation and Air Conditioning systems and the resistive loads within electric furnaces.

Most of the time Thyristors will be involved when handling high currents and voltages, and often when control over alternating currents is needed. They are also used for power supplies for digital circuits; in case the power supply fails and runs the potential of damaging other components.

MasTec Ltd supplies Controllers from three companies

Jumo
AEG of Germany
CD Automation of Italy.

All are leading world supplier of single phase & three phase Proportional Thyristor controllers & IGBT DC Proportional Power Controllers.

AC Loads

AC Loads are a complex piece of equipment much more so than DC Loads.

All these instruments can be interfaced and controlled by computers to make Test Systems automatic. The interface can be LAN (Ethernet), GPIB, (General Purpose Interface Bus) or Serial comms.

All these Test instruments have hundreds of commands built in that you can control with a PC via the interface to make them do certain things for you and they send back heaps of data as they do their testing.

Usually there is a bank of Instruments in a Test Suite, the Itech IT8600 would only be one of several usually.

This field of Test Instruments is huge and very sophisticated.

Anyone building a device that makes AC power would need a device like the Itech IT8600 to verify and document its performance. This is called Characterising or learning the devices personality under every conceivable operation mode.

Applications:

UPS

Inverter

Frequency converter

Generator

AC power supply

Electronic components

 

IT8600 is ITECH latest series of AC/DC electronic loads with power range 0~14.4 kVA and adjustable frequency 45 Hz ~ 450 Hz. The unique oscilloscope waveform display function of IT8600's can display input voltage & current as waveform. It is equipped with measurement modes for different parameters such as inrush current, peak value, effective value, PF (power factor). Voltage harmonics measurement capacity is up to 50th. The built-in RS232, GPIB, LAN and USB communication interfaces are for reliable and fast control. IT8600 is the perfect solution for testing UPS, inverters, AC power supplies and relevant AC electronic components etc.

* 1 IT8615 and IT8615L are with the function

The ELPA-SINE series of programmable electronic loads feature a comprehensive set of both AC and DC test functions.
When in constant current operation the user can select between sine, square and DC waveforms. An adjustable frequency up to 440Hz is provided. Peak currents can be simulated with the crest factor mode. A leading or lagging power factor can be set with adjustments from unity to 0 lagging or leading. The desired wave can be recalled from the front panel or selected via an optional computer interface. The load can also be operated in constant power, voltage, resistance or linear CC modes.

Multiple inbuilt tests include UPS efficiency, PV inverter efficiency, UPS back-up time, battery discharge time, UPS transfer time, short circuit and fuse/breaker trip testing. Other interesting features of the ELPA-SINE include a Turbo mode which can test currents up to double the maximum current of the unit up to 1 second, ideal for inrush current testing.

The 4 digit display simultaneously provides actual values taken by the load. Users can toggle between various measurements for: voltage, current, power, frequency, crest factor, power factor and harmonics. On request the load can be built with a GPIB, RS-232, USB or LAN remote control interfaces. A host of protection features guard the unit against over power, voltage, current and temperature.
