AMO Corporation LMB-410 spar linear encoder

The IP67-rated LMB-410 spar linear encoder from AMO Corporation comes with a stainless steel carrier, offering robust measuring/position feedback with performance similar to a linear optical encoder.

The encoder, operating on an inductive scanning principle, is suitable for general-purpose machines, such as machine tools, medical equipment, printing equipment and military/aerospace applications. Its IP67 rating also makes it 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. Its 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 encoder is rated for operation that ranges from -10 to +100°C for up to 30 m measuring length and ± 3 µm/m accuracy.

Reference marks can be integrated on the measuring tape, and are supplied with a single-, multiple-, or distance-coded patterns. Insensitivity from magnetic interference is achieved by purely inductive scanning without any magnetic components, and also results in no measurement hysteresis (machine backlash error).
