Budget encoders offer potentiometer
replacement
A new range of rotary encoders from Radiatron is claimed to provide high reliability alternatives to conventional potentiometers without the cost penalties normally associated with these devices.
A new range of rotary encoders from Radiatron is claimed to provide high reliability alternatives to conventional potentiometers without the cost penalties normally associated with these devices Sourced directly from the Far East, the encoders feature a minimum operating life of 15,000 cycles with a choice of 15, 20, or 39 indexing pulses per rotation and integral push-button switching action

Rubber keypads offer wide choice of customisation
New from Radiatron is a range of competitively priced silicon rubber keypads that meet diverse application requirements through a wide choice of customisation options.
Two main package sizes are offered: 14 x 14 or 16 x 17.8mm.
Each comes in a choice of vertical or horizontal PCB mounting versions with a variety of shafts, bushings and base colours available as customisation options.
The encoders operate at up to 5V switching voltage and 1 to 10mA switching current.
They have 100mohm maximum contact resistance.
Rotary encoders produce a series of indexing pulses at each of two outputs when the shaft is rotated, each pulse being interpreted as a decrement or increment by the system.
The direction of change is determined by the phase difference of the output lines.
As digital devices, encoders can simplify design by avoiding the need for the analogue interface circuits associated with conventional potentiometers, at the same time providing enhanced reliability and accuracy with reduced mechanical wear-out.
Typical applications include instrumentation, consumer audio, navigation systems, domestic electronic appliances and test equipment.
