Product catalog summary

Overview: The IH490 is an incremental slim design hollow shaft encoder, designed for easy mounting with a floating bearing system. It features a slim housing design of 49 mm and supports shaft bore diameters from 4 to 8 mm. The encoder offers resolutions ranging from 1 to 3600 pulses per revolution (ppr) and operates with supply voltages of 5 VDC, 4.75-30 VDC, and 8-30 VDC.

Electrical Specifications: The encoder supports a maximum current consumption of 40 mA (no load) and is compatible with Push-Pull, TTL, and RS422A output circuits. It can handle a maximum pulse frequency of 100 kHz, with signal levels of Vcc – 0.7 V (high) and a maximum of 0.25 V (low). It includes short circuit and reverse polarity protection, with ESD protection up to 8 kV and burst protection up to 2 kV.

Mechanical Specifications: The body and cover are made of aluminum, while the shaft is stainless steel. It supports a maximum speed of 6000 RPM and has a mass moment of inertia of 95 · 10^-6 kgm². The starting torque at 25°C is greater than 0.04 Nm, with axial and radial shaft loading up to 25 N. It offers shock resistance up to 1000 m/s² and vibration resistance up to 200 m/s². The protection class is IP65, with an operating temperature range of -20° to +70°C, extendable to +100°C with a special option.

Output Signals: The encoder provides various output signal configurations, including A + B + Z and A + B + Z + A\ + B\ + Z\.

Ordering Code: The ordering code includes options for group function, basic series number, shaft size, mechanical options, connection type, connector location, output signals, supply voltage, and resolution. Special functions and designs are designated by a code (Sxxx).

Connection: The encoder's connection functions include GND, Vcc, A, B, Z, A\, B\, and Z\, with corresponding cable color codes.

Accessories: Available accessories include reduction sleeves (B490-8/4 and B490-8/6) and a tether (TEH-490).
