The products feature line driver
quadrature output with index lines and standard resolutions up to 3,587 pulses per inch (141 pulses per mm), a -20[degrees]C to +100[degrees]C or better operating temperature range, 5 V DC to 26 V DC power requirement, and they operate in excess of 100 million cycles.
GSC runs a 15-acre near-dock container yard for line drivers
to quickly pick up a container for delivery or drop-off an empty without having to go to the terminal.
If the strike goes ahead, it will coincide with the second day of a strike by Central line drivers
with the same union.
Those working in the yard often obtain a CDL (commercial driver's license) and become line drivers
