Hercules Series 4000 Heavy Duty Incremental Rotary Shaft Encoder is a product of Infineon, with a maximum speed of 6000 RPM, a maximum bearing load of 30/70 lbs, an accuracy of +0.1º, and output levels of 5 Vdc/ TTL level, 8-15 Vdc.
The Series 4000 encoders feature a slimline 3" × 3" × 1.5" enclosure with NEMA 12/13 or NEMA 4 sealing options, anti‑jitter circuitry, and shatter‑proof metal code discs. They are built with ABEC‑5 stainless‑steel bearings, shielded construction, and offer both TTL and line‑driver output levels.
Mechanical specifications include a maximum shaft speed of 6000 RPM, bidirectional operation, and standard shaft sizes of 0.2497", 0.3747" and 0.4997". Electrical ratings provide a supply voltage of 8‑28 VDC, typical supply current of 30 mA (max 50 mA), pulse rates up to 200 kHz, and various NPN/PNP output configurations. The encoders are rated for -40 °C to +85 °C operation and meet shock, vibration, and humidity standards.
