Allen-Bradley 845H-SJHZ14CRY2C Incremental Encoder

Allen-Bradley 845H-SJHZ14CRY2C Incremental Encoder is a rugged rotary feedback device from Rockwell Automation designed to provide incremental A/B channel pulses for speed and position sensing in industrial machinery. Built for harsh environments, it carries NEMA 4, 13 enclosure ratings and IP66 ingress protection, enabling reliable operation in washdown or dusty conditions. The 845H family is commonly used as a durable incremental encoder that integrates with servo drives, motion controllers, and PLC-based feedback loops to monitor rotation. Key specifications include operating temperature 0 to 60 C (32 to 140 F), storage temperature -25 to 90 C (-13 to 194 F), relative humidity up to 98% non-condensing, shock tolerance about 50 g (11 ms), and vibration around 20 g (4 to 2000 Hz); weight is approximately 0.91 kg (2 lb). The SJHZ14CRY2C variant is part of the 845H product line and is designed for industrial automation environments requiring durable, reliable incremental feedback.
