IH120

Product catalog summary

Overview: The IH 120 is an incremental hollow shaft encoder designed for heavy-duty applications. It supports a range of shaft bores from 1.625" to 2.5" (40 - 65 mm) and operates with a supply voltage of 4.75 to 30 Volts, compatible with RS 422 standards.

Mechanical Specifications: The encoder features a robust aluminum body and stainless steel shaft, supporting a maximum speed of 4000 RPM. It can handle axial loads up to 50 N and radial loads up to 30 N, with an IP 65 protection rating. The device weighs 720 g (1.584 lb) and operates within a temperature range of -20 to +70°C (-4 to +158°F), with an optional extension to +100°C (+212°F).

Electrical Specifications: The encoder consumes a maximum of 40 mA and provides output through a push-pull, RS 422A compatible circuit. It supports a maximum impulse frequency of 300 kHz, with high signal levels at Vcc - 0.7 Volt and low signal levels at a maximum of 0.3 Volt. Short circuit protection is rated at 100%.

Output Signals: The encoder provides A, B, and Z signals with a phase difference of 90°el and 360°el, with A leading B in the clockwise direction. Complementary signals are available, and the resolution can exceed 5000 pulses per revolution using interpolation circuitry.

Connections: The encoder offers various connection types, including 6’ (2Mtr) cable, 9 Pin Sub-D, and 12 Pin connectors. The connection location can be radial, and output signals include A+B+Z and their complementary forms.

Ordering Code: The ordering code is structured to specify the group function, basic series number, shaft size, connection type, location, output signals, and circuit type. Special functions and designs are indicated by a 4-digit code at the end of the part number.

Notes: Customers are advised to specify the supply voltage (5Vdc or 8 to 30Vdc) when ordering. Mechanical options such as shaft seals are available.
