Description:
The S70602-NANANA is an optical encoder from Kollmorgen’s S Series feedback product line. S70602 is the base model. NANANA indicates standard configuration with no special options (no bearing, no custom shaft, no special connector).

Key Specifications:

• Model: S70602
• Type: Optical Incremental Encoder with Index (Z) Channel
• Resolution: 2,048 Lines/Rev (Quadrature = 8,192 Counts/Rev)
• Output Signal: RS-422 Differential Line Driver
• Supply Voltage: 5 VDC ±5%
• Maximum Speed: 8,000 RPM
• Shaft Diameter: 6 mm (Solid Shaft, Clamping Hub)
• Shaft Load Capacity: Radial: 10 N, Axial: 5 N
• IP Rating: IP65 (with proper sealing installed)
• Operating Temperature: -20°C to +85°C
• Weight: ~85 g

Technical Features:

• Glass Code Disc with LED illumination for long-term stability
• Differential RS-422 Output for noise immunity up to 100 m cable length
• Index Pulse (Z-Channel) for home/reference position detection
• A, B, Z Channels with quadrature encoding (×4 decoding recommended)

Structural Characteristics:

• Housing: Aluminum Alloy, Black Anodized
• Shaft: Hardened Stainless Steel, 6 mm Diameter
• Bearing: Precision Ball Bearings
• Seal: Labyrinth Seal + O-Ring
• Connector: M23 or 6-Pin Circular Connector

Working Principle:
Optical encoder uses a glass code disc with precise line patterns. An LED light source passes through the disc onto a photodetector array. Shaft rotation modulates the light to generate A/B quadrature pulses. The index track generates one pulse per revolution for reference position.

Advantages:

• High Resolution: 8,192 counts/rev with quadrature decoding
• Glass Scale — superior to metal scales for accuracy and thermal stability
• Wide Temperature Range for harsh environments
• Long Cable Capability with differential signaling

Applicable Industries: CNC machines, servo motor feedback, robotics joints, printing presses, textile machinery, any closed-loop servo application requiring incremental position feedback

Installation Requirements:

• Mount with 36 mm mounting flange (standard S-series pattern)
• Shaft coupling: flexible coupling only, maximum 0.05 mm misalignment
• Cable: shielded twisted pair, ground shield at controller end only
• Maximum speed: do not exceed 8,000 RPM

Usage Notes:

• Quadrature decoding required in controller (×4 recommended)
• Index pulse width: 90° electrical (25% of cycle)
• Do not subject to shock loads exceeding 50 g
• Re-zero position after any mechanical disturbance
