AMPNH 41

Product catalog summary

Overview: The Absolute Encoder AMPNH 41 is designed with a PROFINET IO interface and PROFIsafe protocol, featuring a hollow shaft type. It ensures functional safety compliant with EN 61508: SIL CL3 and EN ISO 13849: PL e standards. The encoder offers a 13-bit resolution with 32,768 revolutions and provides incremental signals for position feedback with 4,096 pulses.

Specifications:

Electrical Data: Operates on a supply voltage of 13-27 V DC with a current consumption of less than 180 mA at 24 V DC. It supports a transmission rate of 100 Mbit/s and a cycle time of ≥ 1 ms.
Mechanical Data: Weighs approximately 3.1 kg with a permissible speed of ≤ 4000 min-1 for IP54 protection and ≤ 2000 min-1 for IP66 protection. The rotor moment of inertia is approximately 1085 gcm² for IP54 and 785 gcm² for IP66.

Environmental Conditions: The encoder withstands vibration resistance up to 100 m/s² and shock resistance up to 1000 m/s². It operates within a temperature range of -25 to +70 °C and can be stored between -30 °C and +60 °C in dry conditions. It maintains a relative humidity of 98% non-condensing.

Protection and Compliance: The encoder is protected with IP54 and IP66 ratings, ensuring durability in various environments. It complies with EMC standards EN 61000-6-2:2005 for immunity to disturbance and EN 61000-6-3:2007 for transient emissions.
