Product catalog summary

Overview: The RH965 is a redundant/dual incremental hollow shaft encoder designed for industrial applications. It features a US size industry standard of 96.5mm (3.8") and is shaft-mounted with a bore diameter ranging from 12.7 to 25.4 mm (½” to 1”). The encoder is equipped with an electrically isolated redundant reading system and offers resolutions from 1 to 2500 pulses per revolution (ppr).

Electrical Specifications: The encoder operates with a supply voltage of 5VDC, 4.75-30 VDC, or 8-30 VDC input with a 5 VDC output. It has a maximum current consumption of 40 mA (no load) and supports output circuits such as Push-Pull, TTL, and RS422A compatible. The pulse frequency can reach up to 300 kHz, with signal levels of Vcc – 0.7 V (high) and a maximum of 0.3 V (low). It includes short circuit and reverse polarity protection, with ESD and burst protection levels of 8 kV and 2 kV respectively.

Mechanical Specifications: The encoder's 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 96 · 10^-6 kgm² for a bore size of 25mm. The starting torque at 25°C is greater than 0.04 Nm, with axial and radial shaft loading capacities of 120N and 100N respectively. It is designed to withstand shock resistance up to 1000 m/s² and vibration resistance up to 100 m/s². The protection class is IP65, with an operating temperature range of -20° to +70°C (-4° to +158°F), and an optional special high-temperature option up to +100°C (+212°F). The encoder weighs approximately 0.75 kg (1.65 lb).

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 and Pinout: The encoder uses an 8 Pin M12 A-code or 5 Pin M12 A-code for connections, with specific pin functions and cable color codes provided.

Accessories: Available accessories include isolation bushings and a tether kit, with various sizes to accommodate different shaft diameters.
