Technical Specifications

Electrical Characteristics

Power Supply:

10–30V DC (wide-range compatibility for industrial systems).

Output Type:

Typically push-pull or RS-422 (differential) for incremental signals, ensuring high noise immunity and long-distance transmission.

Key Parameters:

No-load Current: ≤70 mA.

Output Frequency: Up to 200 kHz (enables high-speed measurement).

Rise/Fall Time: ~600 ns (fast signal response).

Protection: Reverse polarity and short-circuit protection for robust operation.

Mechanical Characteristics

Housing:

Material: Aluminum (durable and lightweight), with stainless steel shaft (1.4305/AISI 303) for corrosion resistance.

Diameter: 90 mm (compact design for space-constrained applications).

Mass: ~900 g.

Shaft:

Hollow shaft option (bore size varies, e.g., up to 45 mm) for easy integration with mechanical systems.

Insulation Sleeve (optional): PPS GF40 material for electrical isolation, rated for 3 kV insulation voltage.

Mounting:

Flange mounting (3.1645 aluminum flange) for secure installation.

Environmental & Performance

Protection Rating: IP65 (dust-tight and protected against water jets from any direction).

Temperature Range: -25°C to +85°C (operates in extreme industrial environments).

Vibration/Shock Resistance: Withstands 10 g (vibration) and 100 g (shock) for rugged applications.

Functional Safety:

MTTFd (Mean Time To Failure): 140 years (high reliability for safety-critical systems).

Mission Time (TM): 20 years.
