Product Review
The M6-4S1HX51-T003 Avtron M6 incremental encoder is a dependable choice for industrial applications, particularly in oil and gas drilling environments. Users praise its durability, precise performance, and adaptability to harsh operating conditions, making it a trusted solution for continuous production operations.
To address procurement challenges and ensure uninterrupted operations, we offer custom replacement encoders for the M6-4S1HX51-T003. These alternatives are manufactured in a non-standard form but replicate all original application parameters 1:1, guaranteeing a seamless replacement of the original encoder.
The replacement solution is designed to meet the same high standards as the prototype encoder, solving supply shortages and operational bottlenecks. The image provided shows the actual replacement encoder currently in use.
By choosing our replacement solutions, enterprises can maintain productivity without compromising quality, reliability, or compatibility with existing systems.

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!
