Microstepping motor controller ES12ZETTL

stepperfor micromanipulatorsfor actuators

Overview
The ES12ZETTL is a compact single-axis stepper motor controller with encoder input, 10 TTL inputs and 5 TTL outputs. It adds a single high-performance stepper axis to existing or new systems and supports synchronized triggering of external devices.

Functionality and applications
The controller is suitable for motorized Z‑axis drives, rotary multi-position devices (e.g. filter wheels), motorized nosepieces and other stepper-driven components. It can trigger external equipment such as cameras or sensors for image acquisition and automated workflows in microscopy and OEM systems.

Connectivity and options

• USB-C (Virtual COM) and joystick interface for control and integration.
• Optional ES12ADTTL module to convert the high-density TTL port to SMB connectors for flexible cabling.
• Available in bench-top and OEM casework; open-access SDK and multiple DLL interfaces provided for integration.

Key features

• 15 programmable TTL ports (10 inputs, 5 outputs).
• Encoder input for closed-loop operation (AB quadrature).
• Variable motor drive current up to 1.5 A.
• Resolution: 250 microsteps per full motor step.
• Passive cooling (no fan required) and compact footprint.
