Elesa 4 Digit Mechanical Position Indicator Counter, Clockwise Rotation, 85mm Digit Height DD51

Elesa DD51 is a 4-digit mechanical digital position indicator counter engineered for accurate mechanical resolution counting and position indication. Featuring a clockwise shaft rotation and an 85mm digit height, it delivers precise readings suitable for industrial and laboratory applications.

The device is housed in a robust black polyamide technopolymer case, chosen for high resistance and impact durability. Ultrasonic welding of the case prevents tampering and dirt ingress, enhancing longevity in demanding environments.

The rear of the unit is equipped with a brass bushing featuring double sealing, which provides secure mounting and smooth shaft operation. The counter supports a maximum shaft speed of 1250 rpm and a 14mm drive shaft diameter.

Its primary function includes reading the number of shaft turns and providing exact distance measurements relative to the thread pitch of shafts or lead screws. This makes the DD51 ideally suited for machinery settings requiring precise digital position indication.

Applications include material handling equipment, rapid transit vehicles, farm machinery, street sweepers, and recreational carts. The counter’s design lends itself well to industrial automation, process control, and equipment adjustment tasks.

The 4-digit display provides clear digital readings to simplify monitoring and control operations. Clockwise rotation configuration ensures intuitive reading aligned with shaft motion. Durable PA technopolymer case protects internal mechanisms from environmental contamination and mechanical shocks.

Ultrasonic welding technology enhances product integrity and tamper resistance. Double-sealed rear brass bushing ensures long-term reliability of the drive shaft connection. Ideal for diverse industrial and agricultural machinery applications requiring exact position readings.

Manufactured in Italy to strict quality and production standards.

Ensure proper installation by drilling a 6mm deep hole 22mm from the shaft center to accommodate the rear locating pin, and secure with the grub screw. Zero setting the shaft and indicator reading is essential for precise operation.
