A/958SD Absolute Fieldbus Encoder
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Absolute Encoder Fieldbus, SENSORS
The A/958SD is a compact absolute encoder in a very robust Ø58 mm housing, with a DeviceNet interface. It is servo-mounted using clips or front screws and offers high resolution at a very good price/performance ratio.
The A/958SD is a single-turn or multi-turn absolute encoder with a DeviceNet (D2) interface and an ISO 11898 CAN transceiver, featuring programmable baud rates. It allows selection of 4096, 8192, 16384, 32768, or 65536 steps per revolution and 1, 4096, or 16384 revolutions, with a maximum of 30 bits of binary code. It includes two status LEDs and uses SMD technology.
Constructed with a Ø58 mm aluminum housing and a Ø6 f6 stainless steel shaft (Ø10 optional), it supports axial and radial loads of 40 and 110 N. It features IP64 protection on the shaft side (IP66 in the sealed version), withstands 30 G impacts and 10 G vibrations, and operates from -40 to +85 °C. Available in guemisa.es.
- Interface DeviceNet (D2) with CAN transceiver ISO 11898.
- Resolution of up to 16 bit per turn and 30 bit in 16384 turns.
- Programmable transmission speed and 2 LED of state.
- Nutrition 10–30 V DC with maximum consumption of 2.5 W.
