Autonics E40S6-50-3-T-24 Rotary Encoder
Autonics E40S6-50-3-T-24 Incremental Rotary Encoder (40 mm, Solid Shaft, 50 PPR)
Autonics E40S6-50-3-T-24 is a 40 mm solid-shaft incremental rotary encoder with 50 PPR resolution and A, B, Z totem-pole output, ideal for basic speed monitoring and low-resolution position feedback in industrial automation.
The Autonics E40S6-50-3-T-24 is a 40 mm diameter incremental rotary encoder with a solid shaft (Ø 6 mm) and 50 pulses per revolution (PPR) resolution. It provides A, B, and Z phase outputs using a totem-pole output circuit, making it suitable for PLCs, counters, and control systems requiring simple speed or position feedback.
Operating on 12–24 V DC, this encoder is commonly used where low resolution and stable performance are sufficient, such as conveyor speed monitoring and basic machine feedback.
