Encoder Technology

The Model 702 Size 20 Encoder is a heavy duty, extremely rugged, reliable, yet compact industry standard 2″(50.8mm) diameter encoder, designed for harsh factory and plant floor environments.  The double-shielded ball bearings are rated at 35 Kg maximum axial and radial shaft loading to ensure a long operating life. Made to withstand the harsh effects of the real world, both the flange and servo models are rated IP67 with the optional heavy duty shaft seal.  With a variety of mounting options in both the flange and servo models, the Model 702 is ideal for both new applications and replacements.  If you need an encoder that won’t let you down, the Model 702 is it.

Features:

• Standard Size 20 package (50.8mm x 50.8mm)
• Flange and servo mounting
• Up to 30,000 PPR
• 35Kg maximum axial and radial shaft loading
• IP67 sealing available

The Model 711 & 716 Encoder is ideally suited for applications requiring a single or quadrature output.  Designed for compatibility with most programmable controllers, electronic counters, motion controllers, and motor drives, it is ideally suited for industrial applications where it is important that the direction of rotation be known.  Critical performance specifications for the most popular resolutions and advanced Opto-ASIC circuitry — a single chip design that eliminates many board level components — increase the reliability of an already dependable and durable encoder.  With new options continually being added, the Model 711 & 716 excels in a wide variety of industrial applications.

Features:

• The original industry-standard cube
• Five versatile housing styles
• Single or Quadrature output
• New resolutions available to 10,000 PPR

Model 725 Size 25 optical shaft encoder is specifically designed for the challenges of an industrial environment. But don’t let its tough, industrial package fool you — it still has the performance to reach resolutions up to 30,000 pulses per revolution. The Model 725 offers both flange and servo mounting options, and is available in two distinctive housing styles. The rugged Standard Housing isolates the internal electronics from the shock and stress of the outer environment. The extra-heavy-duty Industrial Housing (I) features a fully isolated internal encoder unit that prolongs bearing life by using an internal flexible mount to protect the encoder from severe axial and radial shaft loading. The Industrial Housing option is the recommended solution for applications subject to continuous side loads, such as those that drive the encoder with a measuring wheel, pulley, or chain and sprocket.

Features:

• Standard Size 25 package (63.5 x 63.5)
• Up to 30,000 PPR
• Standard and industrial housings
• Servo and flange mounting
• IP67 sealing available

The 744 is designed to provide a digital encoder signal format to replace traditional Tacho style feedback devices. The heavy duty bearings and mechanical assembly make the 744 perfect for those applications requiring a rugged and dependable encoder.

FEATURES:

• Standard “444” Style, 115mm Diameter
• Up to 30,000 PPR
• Choice of Shaft Sizes
• IP64 Sealing Available

The Model 755HS Encoder is ideal for applications requiring a small, high-precision, and high-performance encoder.  Approximately 38.1mm in diameter and 38.1mm long, it will fit where many encoders cannot.  All-metal construction and shielded ball bearings provide years of trouble-free use.  A variety of blind hollow bore sizes are available with large bores allowing for shafts up to 14 mm.  Attaching directly to a motor is quick and simple with the innovative flex mount, first developed by EPC.  This industry standard mount eliminates couplings and increases reliability, while reducing overall length and cost.  Where critical alignment is required, a Slotted Flex (SF) is available.  A perfect replacement encoder where high reliability is required.

FEATURES:

• Miniature size (38.1mm diameter)
• Up to 30,000 PPR
• Flex mounting & large hollow bore option (Up to 14mm)
• High temperature option

The Model 755RG Encoder is ideal for applications requiring a small, high precision, high performance encoder.  Approximately 38.1mm in diameter and 38.1mm  long, it will fit where many encoders cannot.  Designed with all-metal construction and shielded ball bearings, it will provide years of trouble-free use.  The standard servo mount (RG) version is available with a variety of shaft sizes and lengths.  Three additional servo style mounts (RGS1, RGS2, RGS3) are also available.  The optional flange mountings (M1 & MA) are ideal for applications requiring a bolt-on, high precision encoder.  With its high reliability and quick delivery, the Model 755RG encoder is the perfect replacement encoder in this size category.

FEATURES:

• Miniature size (38.1mm diameter)
• Up to 30,000 PPR
• Servo or flange mounting
• 1 MHz frequency response available
• Extended temperature operating range available

The 760N encoder is configured with either a full thru-bore (which may be fixed at either end of the shaft), or with a blind-bore which uses the front shaft fixing only. The encoder body is retained by means of 2 flexible mountings, or by a single adjustable radius fixing, which compensate for minor shaft misalignment. This encoder can now be provided with commutation signals for use with brushless motor control. Output circuits available include 5-24V Line Driver, 5-24V push-pull or 5-24V input / NPN open-collector. This encoder also now uses the same pioneering Opto-Asic technology used in the model 260 encoder.
