Up to 4MHz with Scaling Function
Backward Compatible with Long-Seller CNT-39, Upgraded Performance with Same Easy Usability

- Connects to various pulse output sensors including rotary encoders, linear gauges, wire encoders, and positive displacement flow sensors.

- Widely applicable for length measurement, angle measurement, displacement, and totalized flow display.

- Supports input frequencies up to 4MHz, A/B phase pulses (up to 1MHz), and direction signal inputs to achieve error-free reversible measurement.

- Offers diverse options, including a high-speed 16-bit analog output updated every 0.5ms.

- Highly effective in research experiments and factory automation lines.

Input Frequency: 0 to 4MHz (Single-phase) / 0 to 1MHz (A/B-phase) - No Range Switching Required

Scaling Function

Arbitrary settings for the accumulated value per pulse and the decimal point display position.

Full 6-Digit Display & 4x Quadrature Counting

Enables 4x quadrature counting capability for A/B-phase signals.

Standard Equipped with 2-Channel Non-Contact Output Comparator

External Control

Direct external control for Preset, Reset, and Hold commands.

Programmable Forward/Reverse Direction Switching - No Re-wiring Needed (A/B-Phase)

Allows instant adjustment via parameter settings for any wiring errors or changes in testing conditions.

Settings can be easily adjusted using the 4-button array behind the front panel or via the PC software LINKSHIP.

A) COCORESEARCH's unique mounting mechanism: Enables single-handed installation from the front panel.
B) Front cover can be removed tool-free by pressing the left and right levers.

RS-232C Communication

Transfers live measurement data to a computer and allows setup configuration via LINKSHIP.

*Requires an RS-232C communication cable (sold separately). Model: CSS-M06D09 (D-SUB 9-pin) or CSS-M06D25 (D-SUB 25-pin)
Cable Length: 2.5m
*Please consult us regarding continuous data streaming output compatibility via RS-232C.

Options

Extended Comparator Output (2-Channel)

Adds 2 additional channels to the standard 2-channel comparator output, providing a maximum of 4 channels for highly flexible HIGH/LOW alarm combinations.

4 Types of Analog Output Options

Selectable upon ordering from four formats: 0-10V, 1(0)-5V, ±10V, or 4(0)-20mA. Delivers an ultra-fast update cycle of up to 0.5ms with 16-bit high resolution.

BCD Parallel Output

Outputs a signed 6-digit parallel signal via open collector, TTL, or CMOS. Simplifies direct interfacing with PLCs, large display remotes, and digital logging printers.
*With BCD connector attached
