EM58 TA: easy teach-in in just two clicks Yes, that's right, it takes just two clicks to set up the new EM58 TA analogue absolute encoder. No need for either interfacing cables or configuration programs, simply press the two keys and the encoder will be immediately ready for your measuring needs! EM58 TA is the new absolute encoder with analogue signal outputs which adds a further benefit to the well-known technology and quality standards of Lika Electronic: it is very simple and user-friendly and easy to operate. It really requires just a few seconds in order to set up and best suit your specific installation. The core advantage is the new TEACH-IN procedure which is able to stunningly help your work and greatly ease the configuration. Two keys fitted in the rear of the enclosure (or two external inputs, as an alternative) allow you to simply define the linear or angular displacement of your application by setting the start and stop reference points of the measuring range. Thus the initial and final limits of the stroke are the minimum and maximum values of the analogue range respectively. That's all. It doesn't matter whether the displacement you need to measure is 1-, 25- or 99.5-revolution long, it will be scaled in the whole analogue range.
Two LEDs next to the keys help during setting. EM58 TA offers a wide variety of both voltage and current analogue signals: 0 to 5V, 0 to 10V, -5 to +5V, -10 to +10V, 4 to 20mA, 0 to 24mA and 4 to 24mA. Further benefits include the OVERRUN function implemented in the 4-20mA encoder model. It operates as a limit switch and allows to detect an overtravel position by decreasing (to 3.6mA) or increasing (to 22mA) the output value beyond the analogue range. Anyway, in all models the signal level is kept low/high outside the set axis travel. Furthermore to warn against a circuit interruption a FAULT output is
provided (current output models only). EM58 TA boasts a number of information up to 226 and a 16-bit analogue resolution, with ±0.02° accuracy. It employs optical technology, thus it is insensitive to magnetic fields and does not require batteries. Output connection can be either cable or M12 connector. Mechanically it affords standard 58-mm flange diameter housing with both hollow (Ø 14, 15 mm) and solid (Ø 6, 8, 9.52, 10, 11, 12 mm) shafts. Thanks to the high IP67 protection rate (IP65 at shaft) and the ability to withstand large temperature ranges (-25°C +85°C, 13°F +212°F) as well as high radial and axial shaft loads, EM58 TA is suitable for installation in industrial and even harsh applications and finds typical use in construction vehicles, utility vehicles, construction equipment, building material machines, cranes and hoists.
Your motor needs MORe! The MOR tenet: smaller is tougher. Smaller foot-print, increased bore range, higher torques, reduced burden on the shaft. MOR is the new Oldham-type flexible coupling series ideally suited for integration into stepping motors, general-purpose motors and rotating shafts in general. The spacer's and hub's new design allows to reduce the overall footprint while widening the bores selection and increasing the rated torque at the same time. The spacer, in hard polyacetal for good mechanical characteristics and resistance to wear, fatigue and chemicals, affords a new projection structure which allows larger lateral and angular misalignment to be effortlessly accepted since the projection acts as a support. Thus the bending moment does not arise and the allowable angular misalignment is increased up to 3° (instead of 1° - 1.5° in comparable models).
from being very wide and rather increased next to comparable models. For example the setscrew type MOR-20 model boasts a huge 4 to 12 mm (0.16” to 0.47”) diameter range in a compact structure featuring a 20 mm (0.79”) outer diameter and a 21.4 mm (0.84”) overall length. MOR can be ordered with different bore diameters at hubs. Furthermore, it is electrically insulated (up to 20 kV) in order to preserve the integrity of the unit from damages due to eddy currents. MOR series is available in the range from 6 to 68 mm resin spacer Oldham-type couplings (0.24” to 2.68”) outer diameter and and up to 160 Nm. In addition MOR 1 to 38 mm (0.039” to 1.5”) bore is able to excellently absorb the diameter, with setscrew type, clamvibrations since the amplitude ping type, key type and clamping + key type hubs. under natural frequency is low.
