Maintaining industry-acceptable dimensions on shafts and bores is necessary to ensure the proper fit between encoders and the machinery they are installed on. With sufficient clearance between a bore and a shaft, a slip fit is possible. Without a proper fit, encoders often are damaged during installation, accuracy is reduced, or their life is shortened. […]
Size 25 shaft encoders (2.5”/63.5mm diameter), along with their 58 mm diameter European equivalents, are among the most popular encoders in the world. As a result, nearly every encoder manufacturer in the world makes them. This technical bulletin identifies and compares important features of Size 25 shaft encoders, including typical designs, and the British Encoder […]
BEPC offers a converter that can convert single-ended output signals to differential signals, and vice-versa: the RX/TXD Receiver-Transmitter. The RX/TXD can convert single-ended signals into differential (RS422) signals for superior noise immunity. This allows an existing encoder with a single-ended output (Open Collector, Pull-up, or Push-Pull) to be used in applications where the differential signal type is […]
Choosing the correct number of channels and the correct output type for an encoder can be the determining factor in whether or not a feedback system functions properly. There are four common output types to select from, and most of BEPC’s encoder models can be ordered with any of these four types. There are also […]
A common method for creating a linear measuring solution is to use a rotary encoder in conjunction with a measuring wheel. For many applications, a rotary encoder with a measuring wheel has several advantages over a linear scale encoder. When using an encoder with a measuring wheel, rather than a linear scale encoder, the application […]
In an encoder, mechanical jitter is any vibration in the assembly affecting the relationship between signal producing components (i.e., disc, sensor, and light source). Mechanical jitter can have many causes, such as cogging of the input shaft, excessive loading or runout, and vibration of the encoder induced by the application. Depending upon the severity of […]
British Encoder Products Company uses the international standard IP Code, International Protection Marking, IEC standard 605291, for specifying the sealing qualities of our units. The chart below explains what the different numerical designations define. Note that the designations build on the previous ones; that is, an IP69K rating means that unit is also protected against […]
British Encoder Products Company (BEPC) offers several index pulse gating options on most encoder models. The index pulse is also referred to as the reference, marker pulse, or home pulse. This pulse is an individual output channel provided by the encoder that provides a single pulse once per revolution. It simply notes some discrete and […]
