Product catalog summary
Product Overview: The IH 490 is an Incremental Hollow Shaft Encoder designed for compact construction and shaft mounting. It offers a maximum of 3600 Pulses Per Revolution (PPR) and is compatible with RS 422 standards.
Electrical Specifications: The encoder operates within a supply voltage range of 4.75 to 30 V DC, with a maximum current consumption of 40 mA. It supports a maximum impulse frequency of 100 kHz. The output circuit is Push-Pull, RS 422A compatible, with logic levels of Vcc - 0.7 Volt (high) and 0.25 Volt (low). It includes 100% short circuit protection.
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 axial loading capacity is 20 N, and radial loading is 15 N. It is rated with an IP 65 protection level and can function in temperatures ranging from -20˚ to +70˚ C (-4˚ to +158˚ F). The weight of the encoder is 0.29 lb (130 g).
Output Signals: The encoder provides output signals A, B, and 0, with A leading B in the clockwise direction when facing the shaft. Complimentary channels are also available.
Ordering Information: The ordering code for the encoder includes specifications for shaft size, mechanical options, connector type and location, output signals, and output circuit type. Special functions and designs are indicated by a four-digit code at the end of the part number.
Additional Information: Drawings are available in various formats including dxf, iges, step, and sld files. The encoder features a mini-PG with two set screws (M3x5) spaced 120 degrees apart.
