•Shock and vibration resistant
•Choice of three mounting styles, with or without watertight case
•Rugged components designed for the construction environment
•High-torque handle actuation gives sure feel
•Simple to install
•Mechanical options include center-lock, spring-return, friction drag, uni/bi-directionality and optional wire harness with a variety of electrical connectors
•Electrical characteristics customized to the application

has 30 degrees of handle throw on either side of center. |
|
|
|
B |
Friction held, bi-directional |
This handle has an adjustable drag, set with a clamp-type brake that holds the |

Handle actuation option (continued)
Code |
Description |
Detail |
|
|
|
C |
Friction held, uni-directional |
This handle has 60 degrees of high-resolution of handle throw, rotating on only |
|
|
one side of mechanical null, which is at full stroke. |
|
|
It has no detent mechanism. |

Electrical characteristics option
Code |
Description |
Detail |
|
|
|
A |
Proportional, no switches, 12 VDC |
This handle’s output curve is fairly linear, with output voltage as a function of |
|
|
handle stroke. |
|
|
The supply voltage is 12 Volts, and there are no auxiliary function switches. |
|
|
|
B |
Proportional, center off switch, 12 VDC, |
This handle has a center-off switch that ensures zero output voltage within ±3 |
|
|
degrees of handle center position. |
|
|
|
C |
Proportional, center off switch, 24 VDC |
Same as option B except this handle runs on a supply voltage of 24 Volts. |
|
|
|
D |
Proportional, center off and auxiliary switch, 12 VDC |
Same as option B except this handle has a second switch that actuates at +2 or -2 |
|
|
degrees. |
|
|
|
E |
Proportional, set-point potentiometer, 12 VDC |
Same as option B except this handle maintains the same polarity of signal in |
|
|
forward or reverse. |
|
|
|
F |
Step-plus-proportional, 12 VDC |
This handle uses two switches to give the step-plus-proportional output current |
|
|
on either side of null. |
|
|
This overcomes deadbands in spool valves (see Specifications on page 8, Step- |
|
|
Plus-Proportional-Control-Handle PWM option illustration). |
|
|
Current beyond this step output is proportional through the rest of the handle |
|
|
throw. |
|
|
Full current output at 30 degrees handle stroke is maximum of 250 mA. |
|
|
Step current is a maximum of 50% of full current output. |
|
|
|
G |
Step-plus-proportional, 24 VDC |
Same as option F, except this handle runs on a supply voltage of 24 Vdc. |
|
|
|
H |
Switching |
This handle is non-proportional. Moving the handle off null activates switches |
|
|
that power ON/OFF devices (for example, solenoid valves). |
|
|
|
J |
Step-plus-proportional, full auxiliary switching, 12 |
This handle uses the step switches for additional secondary functions. |
|
VDC |
Full current output at 30 degrees handle stroke is a maximum of 250 mA. |
|
|
Step current is a maximum of 50% of full current output. |
|
|
|
K |
Proportional, unwired switch |
The customer uses the unwired center switch to operate an auxiliary function, |
|
|
such as neutral start interlock. |
|
|
|
L* |
Electronic PWM auxiliary switching, 12 Vdc |
This handle uses a printed circuit board that makes the step height and output |
|
|
current fully adjustable, accommodating high current applications. It also has |
|
|
pulse width modulation, that dithers the output to overcome hydraulic valve |
|
|
stiction. Full current output at 30 degrees handle stroke is a maximum of 2 Amps |
|
|
into a 5 Ohm load. Step current is a maximum 50% of full current output. Typical |
|
|
dither frequencies (dependent on resistance of the load, specified in the suffix |
|
|
number) are: 60 Hz for the HPI solenoid actuator, approximately 400 Hz for the |
|
|
V7058 Hydrotransmission Valve and approximately 1000 Hz for the MCV101A/ |
|
|
MCV116A Pressure Control Pilot Valve. |
|
|
|
M |
Proportional, three switches |
The three switches are: a wired center switch; one unwired switch in forward; and |
|
|
one unwired switch in reverse. |
