For customers experiencing difficulties in sourcing the M6C-4S1XH51-W005 Avtron M6C incremental encoder, we provide a specialized non-standard customized replacement service. Unlike mass-produced items kept in large inventories, our solution is based on tailor-made production that ensures precise compatibility with the original unit in both mechanical and electrical aspects. This approach allows us to deliver reliable alternatives without requiring extensive stock levels, which helps our clients overcome long procurement lead times. In general, our production cycle is approximately 15 working days, enabling customers to receive a fully compatible product within a short timeframe. By offering this service, we help reduce downtime risks in critical industrial operations and provide an efficient solution to procurement challenges.
The Avtron M6C encoder series has earned a strong reputation in heavy-duty applications where durability and accuracy are essential. A key example is its use in oil drilling winches, where reliable position and speed feedback are critical to the safe and efficient control of the drilling line. In such operations, the encoder must withstand harsh conditions including vibration, shock, and exposure to dust, oil, and extreme temperatures. The M6C encoder’s robust design and high performance make it particularly well suited to these demanding environments. By supplying a compatible replacement, we ensure that operators in industries such as oil and gas, steel manufacturing, mining, and material handling can maintain stable system control, protect equipment integrity, and guarantee operational safety without the delays associated with difficult-to-source original models.

Introduction
Avtron M6C explosion protected ATEX and IECEx rated severe mill duty rotary encoders are designed for direct mounting on motor or load shafts, from 1" to 1 1/8" [25-30mm].
The M6C is an updated model which directly replaces the M6 encoder, and M6C adds IECEx certification. No barrier or isolator is required-mount M6C directly in any ATEX or IECEx Zone 1 application.
Why take a chance with weak optical encoders on your drilling rig? The M6C features Avtron Encoders' rugged magnetic sensor and solid metal rotor technology. Our shatterproof, moisture proof systems ensure your application has maximum uptime. The hollow shaft (tethered) models offer direct mounting on shafts from 1" to 1 1/8", without flanges, reducers, couplings, or other hardware. No rework is needed; just mount the encoder directly on the shaft, and secure the tether arm. The heavy duty bearings withstand runout and vibration that destroy lesser encoders.
M6C also includes a complete wiring protection system--it can survive all types of wiring errors and drive signals down the longest cables.

We believe explosion protected encoders should also be ready to withstand the rough drilling environment. Try the M6C today!
