AMO Corporation LMB-410 spar linear encoder

AMO Corporation has released the IP67-rated LMB-410 spar linear encoder.

The LMB-410 measuring scale comes with a stainless steel carrier, offering robust measuring/position feedback with IP67 rating and performance similar to a linear optical encoder.

Its IP67 rating makes the scale suitable for dirty or contaminated conditions including being fluid submersible.

Its adhesive-free mounting spar with a snap cover eliminates concerns related to adhesive-backed spars becoming loose in oily environments. A slim stainless steel carrier is attached to the machine with screws, with an interlocking snap cover securing the scale tape in position. The encoder head can be optionally equipped with wipers to automatically clean the scale during operation. The encoder head’s gain compensation and auto offset eliminate the need to use a test box during set-up.

The LMB-410 is rated for operation that ranges from -10 to +100°C for up to 30 m measuring length and ±3 µm/m accuracy. The encoder also meets high-shock, high-speed and vibration specifications.

Any non-guided Amosin encoder head can be used with any of the LMB-400 or LMB-100 scale mounting versions. The Amosin inductive measuring systems are supplied in two principal versions: an open, non-contacting system or as a guided, encapsulated system.

Reference marks can be integrated on the measuring tape and are supplied with a single, multiple or distance coded patterns. The purely inductive scanning allows for the high protection class IP67 where the operation of the systems is not affected by contamination and pollutants in the form of dust, smoke or liquids. Optical encoders require a complicated mechanical encapsulating enclosure, are more susceptible to damage and hence commonly incorporate air purging to protect the optical scale - none of which are necessary with the Amosin encoders. As a result, Amosin encoders require much less maintenance than optical encoders.

The unit is insensitive to magnetic interference as there are no magnetic components in the purely inductive scanning and a completely different technology than magnetic encoders. As a result, Amosin encoders are not at all sensitive to electromagnetic interference of any kind and have no measurement hysteresis (machine backlash error).
