Encoders Baumer Hubner

High-Resolution Optical Sensing

• Pulses per revolution range from 300 up to 25,000 — a wide span that covers both moderate-resolution speed feedback and fine-grained positioning applications from the same base encoder design.
• Phase shift held to 90°±2° and scan ratio of 40–60%, giving tight signal accuracy across the resolution range.
• Reference (zero pulse) signal at 90° width supports applications requiring a defined home position each revolution.

Very High Shock Resistance

• Rated to 300 g shock (1 ms) — a notably high tolerance for sudden mechanical impact, suited to equipment subject to jolts, rapid starts/stops, or occasional mechanical shock during operation.
• Combined with 10 g vibration resistance (10–2000 Hz), the encoder is built to keep producing accurate signals through the kind of mechanical disturbance that would degrade a standard-duty unit's readings over time.

Long-Distance Signal Transmission

• TTL output driver supports cable runs up to 500 m, letting the controller be positioned well away from the encoder on larger machines or plant layouts without signal degradation.
• Dual output stage support — HTL-P (power line driver) and TTL/RS422 — lets the encoder match whichever interface the connected controller expects.

Dual Shaft-End and Monitoring Options

• Optional second shaft end allows a mechanical coupling or additional sensor to be mounted on the opposite side of the encoder from the primary drive connection — useful where a single shaft needs to drive more than one device.
• Optional Function Control with EMS (Enhanced Monitoring System) adds a dedicated error output, giving continuous diagnostic feedback on encoder health and helping catch faults before they cause a process interruption.

Solid Shaft, EURO Flange B10 Mounting

• 11 mm solid shaft with EURO flange B10 mounting — the recognized industry-standard mounting format for this class of encoder, simplifying integration with existing machine designs already built around this flange type.
• Handles shaft loading up to 250 N axial and 350 N radial, and operates at up to 12,000 rpm mechanical speed.

Rugged Environmental Rating

• IP56 protection (DIN EN 60529), a step up in sealing from standard IP-rated encoders, suited to environments with heavier dust or water exposure.
• Operating temperature range of -30°C to +100°C.
• Explosion-protected variants available: II 3 G Ex nA IIC T4 (gas) and II 3 D Ex tc IIIB T135°C DC (dust), suitable for Zone 2 hazardous area classification.

Durable Construction

• Aluminium die-cast housing with a stainless steel shaft, connected via terminal box.
• Weighs approximately 1.4 kg, with an operating torque of 2 Ncm and rotor moment of inertia of 200 gcm².

Applications

• Precision positioning tasks in harsh environments – the combination of high resolution (up to 25,000 ppr) and 300 g shock resistance suits machinery needing both accuracy and mechanical toughness.
• Large machines and plant layouts – 500 m TTL cable capability supports installations where the controller sits far from the encoder.
• Multi-device shaft mounting – the optional second shaft end supports applications needing to drive an additional coupling or sensor from the same shaft.
• Hazardous area installations – Zone 2 gas and dust rated variants allow direct use in classified plant areas.
• Steel, materials handling, and heavy machinery – dust and moisture resistance (IP56) combined with wide operating temperature range suit demanding industrial floor conditions.
