Sick ATM60-A4A00S01 Absolute Encoder

Sick ATM60-A4A00S01 Absolute Multiturn Rotary Encoder (Part No. 1061966)

The Sick ATM60-A4A00S01 (Manufacturer Part Number: 1061966) is a magnetic multiturn absolute rotary encoder engineered for high-vibration, shock-intensive motion control environments. Operating on a 10 to 32 V DC auxiliary rail, the encoder outputs absolute position data through a synchronous serial interface (SSI) supported by an integrated RS-422 bidirectional programming bus.

Unlike optical encoders with glass disc assemblies that crack under mechanical shock or thermal cycling, the ATM60 series uses an optical-free magnetic scanning system. It retains genuine absolute positional status across 4,096 steps per revolution (12-bit singleturn) over 4,096 revolutions (12-bit multiturn) without relying on internal backup batteries. When coupled with an IP67-rated radial M23 12-pin connector housing, it serves as a drop-in component for demanding marine deck machinery, offshore cranes, bow thruster feedback loops, and harsh factory automation lines.

Model Details

Features

1. True Non-Volatile Multiturn Tracking: Delivers 24-bit total resolution (12-bit singleturn × 12-bit multiturn) using gear-driven magnetic scanning; mechanical position is preserved without external or battery power during total blackouts.
2. Wide Range Power Supply Input: Tolerates input fluctuations between 10 V DC and 32 V DC, allowing direct integration into unconditioned 24 V DC shipboard battery distribution networks.
3. High-Speed Noise-Immune SSI Protocol: Supports SSI clock rates up to 1 MHz with differential RS-422 transmission lines (Clock±, Data±) for long cable runs through high-EMI machinery spaces.
4. On-the-Fly Hardware Calibration: Dedicated SET (Pin 9) and V/R (Pin 12) control lines permit direct zero-point preset calibration and electronic rotational count reversal (CW/CCW) in the field without software.
5. Severe Service Enclosure Rating: Rated to IP67 with an integral shaft seal, certified for 100 g shock resistance (6 ms) and 20 g vibration resistance (10 to 2,000 Hz).

Frequently Asked Questions

What does the “S01” suffix represent in ATM60-A4A00S01?

The “S” suffix in SICK encoder nomenclature indicates a customer-specific or custom-parameterized special execution. On the ATM60-A4A00S01 (1061966), this typically references a factory-preset telegram configuration (such as specific singleturn/multiturn step divisions or preset Gray/Binary output format) built for designated marine or material-handling control equipment while retaining standard ATM60 face mount mechanicals.

Does the ATM60-A4A00S01 lose its position count during a power outage?

No. The ATM60 is a true multiturn absolute encoder. It uses a non-contact magnetic gear-train mechanism rather than an electronic revolution counter backed by a battery. Even if the machine axis turns while 24 V DC power is completely switched off, the encoder immediately outputs the exact mechanical position over the SSI line as soon as supply voltage returns.

Can I replace an ATM60-A4A12x12 with an ATM60-A4A00S01?

In most applications, yes. Both units share identical mechanical footprints: a 60 mm diameter face mount flange, a 10 mm solid shaft, an IP67 enclosure, and a radial 12-pin M23 connector. However, verify that your PLC expects the exact same code structure (Gray Code vs. Natural Binary) and resolution bits. If re-parameterization is needed, settings can be updated using SICK’s PGT-01-S hand-held programming tool via Pins 4 through 7.

How do I reverse the counting direction without reprogramming the unit?

Counting direction is hardware-configurable via Pin 12 (V/R wire, orange-black). Leaving Pin 12 unconnected (or connected to HIGH configures the encoder to count upwards when looking at the face of the shaft turning clockwise. Connecting Pin 12 directly to 0 V DC (GND) reverses the sequence, making the position increment counter-clockwise.
