New Illuminated Rotary Encoders from Cliff

Rotary encoders are widely replacing conventional analogue potentiometers for audio, instrumentation and industrial control functions as they offer more accurate, repeatable setting. Cliff’s rotary encoder range features LED illuminated spindles to provide visible indication of panel position or function. Standard LED colors available are blue, green and red. The company is now manufacturing a wide range of customizable translucent control knobs in its UK factory in eight solid colors. The control knob are available to fit standard pot and encoder shafts. Custom designed translucent knobs are also available on request.

“The provision of an LED illuminated shaft provides integrated indication to simplify and reduce the cost of control panels by eliminating the need to fit a separate LED indicator. Our experience of manufacturing control knobs in-house puts us in a unique position to provide a range of matching translucent control knobs for our own and other suppliers illuminated rotary encoders.” Says Cliff Electronics General Manager John Hall

The rotary encoder range provides an output of 24 pulse / 24 clicks and features a 24mm shaft with ‘flats’ of 15/17.5/20/25/30mm available. Switch contacts are rated at 5VDC/0.5mA and the operating temperature range is -40° to +85° making them ideal for audio, broadcast, industrial control, medical and telecoms equipment and many types of portable devices.

Low Profile Encoders from HEIDENHAIN

HEIDENHAIN Corporation now introduces new low profile incremental rotary encoders with block commutation tracks, especially suitable for use in small-dimensioned servo motors.  These new rotary encoders of the HEIDENHAIN 1000 and 1100 series come equipped with an industry-standard 35 mm housing diameter.

These new encoders distinguish themselves not only by their short overall length but also by their modern opto-ASIC based photoelectric scanning with integrated interpolation.  Thanks to the electrical output at TTL levels with differential signals, these encoders can be connected to almost all standard subsequent electronics for control of digitally controlled servo motors (up to edge lengths of 40 mm and 55 mm), and are useful in various applications in the Automation industry.

Currently available, the HEIDENHAIN 1023 encoder has an overall length of 35.2 mm max and an IP 64 rating, making it especially useful in hazardous environments; the HEIDENHAIN 1123 encoder has an overall length of 30.3 mm max and an IP 0 for general use.

Both encoders have mounted stator couplings and blind hollow shafts.  Choice of appropriate commutation signals is available to the buyer as the amount depends upon the number of poles of the motor to be controlled.

Stainless Steel Rotary Encoders from AMCI

Terryville, CT – AMCI’s DuraCoder® brand encoders are now available with stainless steel housings and an IP69K rating for operation in the most extreme conditions. AMCI DuraCoders have a superior shaft load rating; providing a longer life cycle than other encoders. Many industrial applications require encoders that withstand a variety of harsh environments. AMCI’s stainless steel DuraCoders reliably perform in applications where standard encoders fail.

With a standard IP67 rating, and IP69K rated versions available, end-users can take advantage of the DuraCoder’s protection against high pressure and high temperature wash downs; or liquid ingress from long-term immersion in water or contaminants. The DuraCoder product line comes standard with a 2.5” (63mm) housing and an oversized double row sealed bearing. Solid shaft and hub shaft versions are available with a variety of sizing options. Shaft loadings of up to 100 lbs. radial/50 lbs. axial provide maximum durability for applications that require superior strength. DuraCoder brand encoders are available in six different versions: SSI, Digital, Analog, Incremental, DeviceNet, and Ethernet/IP.

Applications that benefit from the stainless steel DuraCoder design include food/beverage processing, specialty vehicles, cranes, energy generation equipment, chemical/petroleum processing, wastewater treatment plants, offshore/marine environments, steel mills, and many other indoor and outdoor installations. With the ability to withstand the harshest environments, the DuraCoder remains the perfect solution for heavy-duty applications.
