IH581

Product catalog summary

Product Overview: The IH 581 is an incremental hollow shaft encoder designed to meet industry standard size 25 specifications. It is shaft-mounted and offers a maximum of 10,000 pulses per revolution (PPR).

Electrical Specifications: The encoder operates with a supply voltage range of 4.75 to 30 V DC and is compatible with RS 422. It has a maximum impulse frequency of 200 kHz and a current consumption of 40 mA. The output circuit is push-pull, RS 422A, with logic levels of Vcc - 0.7 Volt (high) and 0.25 Volt (low). It includes 100% short circuit protection.

Mechanical Specifications: The encoder features an aluminum cover and body with a stainless steel shaft. It supports a maximum speed of 6000 RPM and a torque greater than 0.04 Nm. The axial loading capacity is 20 N, and radial loading is 15 N. It is protected to IP 65 standards and operates within a temperature range of -20˚ to +70˚ C, with an optional extension to +100˚ C.

Physical Dimensions: The encoder has various shaft bore sizes ranging from 6.35 mm to 12.7 mm. The weight is approximately 0.55 lb (250 g).

Output Signals: The encoder provides A, B, and 0 output signals, with complimentary channels available. The A channel leads the B channel in the clockwise direction when facing the shaft.

Ordering Information: The ordering code is structured to specify group function, basic series number, shaft size, mechanical options, connector type and location, output signals, and output circuit type. Special functions and designs are available upon request.

Connection Details: The encoder includes a 12-pin connector with a specific color code for each function, including 0 Volt, + Volt, A, B, and 0 signals.
