The Gemco Quik-Stik II

Gemco brand position sensing products have been
known for reliability and high resolution. We have taken
over twenty years experience in magnetostrictive linear
sensors and married it with our understanding of rugged
industrial applications to develop the Quik-Stik II LDT,
with patented design for high resolution magnetostrictive
linear sensing.

The Quik-Stik II LDT is fi eld proven to provide
top performance & repeatability. The on-board
microprocessor is programmed to compensate for
variables and to linearize outputs, providing high
resolution and linearity. The Quik-Stik II LDTs rugged
sensing tube construction is welded stainless steel,
suitable for insertion in 5000 PSI hydraulic cylinders. The
electronics are enclosed behind an anodized housing
with O-ring seals for IP67 indoor applications (Type 6
rating available as a special option). There is no need to
re-calibrate the sensor once installed.

The Quik-Stik II LDT is available in Analog, Start/Stop
Pulse, Control Pulse or Variable Pulse versions. The
analog units offer 16 bits of resolution and are available
with voltage or current outputs. The output format,
voltage or current, is hardware specifi ed. If voltage
outputs are specifi ed, the unit can be programmed for
voltage type 5 VDC or 10 VDC, polarity, span, and zero
reference point. The ability to select voltage type and
polarity allows selection of 0 to 5 VDC, 0 to 10 VDC, -5
to 5 VDC, or -10 VDC to 10 VDC output. The current­type units are programmable for polarity, span, and zero
reference. The units are programmable via a hand-held
programmer or RS232 serial communications. As an
added benefi t, the 951 has an optional 12-Bit Velocity
output that can provide a separate analog output of
speed.

The Quik-Stik II LDT, with its high resolution and
industrial construction, is at home in areas such as
assembly automation, material handling, robotics, and
any other industrial area where highly accurate and
reliable continuous linear position sensing is needed.
Units are available with radiused (curved) probes and in
a rugged mill-duty housing.

Each style of Quik-Stik II LDT is fi eld programmable for
a variety of functions via RS232. ASCII characters are
used to represent each function. Common characters

are used for all styles, with functionality of the characters
changing from unit to unit. This allows the hand-held
programmer to be used with all styles of LDTs. The serial
communications is set at 9600 baud, no parity, eight
bits, one stop bit. Particular code representations will be
provided with each unit.
