Allen Bradley Absolute Encoder, 18 Bit Resolution, 10 to 30V DC Supply Voltage – 842E-SIP7BA
Use this absolute encoder from Rockwell Automation’s Allen Bradley range to assess object positions and speed in your industrial equipment. It comes with five LED indicators to provide clear status displays that support simple troubleshooting and maintenance. The unit’s shaft can bear an axial load of 40N and a radial load of 80N, so it’s ideal for use with heavy-duty machinery. A maximum revolution speed of 6000rpm makes this a suitable option for fast-paced applications. Thanks to its current rating of 200mA, this absolute encoder is energy-efficient and emits low heat.
Features & Benefits
• Bearing lifespan of 3 billion cycles for long-term performance
• Can be flange mounted for simple installation
• Supply voltage of 10 to 30V will suit low-voltage systems
• IP67 rating indicates it’s dustproof and resistant to immersion in 1m of water for 30 minutes
• Can withstand up to 100g of impact for high shock resistance
