IS280
Product catalog summary
Product Overview: The IS 280 is an incremental shaft encoder with a micro-miniature size, offering a maximum of 1024 pulses per revolution (PPR). It operates within a voltage range of 4.75 to 30 volts and is compatible with RS 422A standards. The encoder supports a maximum frequency of 100 kHz.
Electrical Specifications: The encoder features a push-pull output circuit compatible with 422A standards. It has a current consumption of 40 mA (maximum) and provides short circuit protection at 100%. The logic levels are defined as Vcc - 0.7 Volt for high and 0.25 Volt (maximum) for low.
Mechanical Specifications: The encoder is constructed with an aluminum cover and body, and a stainless steel shaft. It can operate at speeds up to 6000 RPM with a torque greater than 0.04 Nm. The loading capacity is 30 N axially and 20 N radially. It is rated with an IP 65 protection level and can function within a temperature range of -20˚ to +70˚ C (-4˚ to +158˚ F). The weight of the encoder is 0.24 lb (110 g).
Output Signals: The encoder provides output signals A and B, with A leading B in the clockwise direction when facing the shaft. A complimentary channel is also available.
Ordering Information: The ordering code is structured as follows: IS (Incremental Solid Shaft), 280 (Basic Series Number), followed by options for shaft size, mechanical options, connector type and location, output signals, and output circuit type. Special functions and designs are indicated by a 4-digit code at the end of the part number.
Connection Details: The encoder uses a color-coded cable system for connections, with specific colors assigned to each function (e.g., white for 0 Volt, brown for + Volt).
Additional Information: Drawings are available in various formats including dxf, iges, step, and sld files.
