Model Selection

The P16 has 3 configuration choices: Stroke, Gear Ratio and

Controller. P16 options are identified according to the

following model numbering scheme:

P16-SS-GG-VV-C

Feature Options

SS: Stroke 50, 100, 150,200 (mm)

GG: Gear reduction

ratio (refer to load

curves above)

22, 64, 256 :1

(lower ratios are faster but push

less force, and vice versa)

VV: Voltage 12 Volts DC

C: Controller P Potentiometer Feedback

S Limit Switches

P16 Controller Options

Option S – End of Stroke Limit Switches

WIRING: (see last page for pin numbering)

1 - Red – Motor V+ (12V)

2 – Black – Motor V- (Ground)

–S actuators are ideal for manually controlled applications and

simple two position automated mechanisms. The –S actuators

have limit switches that will turn off power to the motor when

the actuator reaches within 0.5mm of the end of stroke.

Internal diodes allow the actuator to reverse away from the

limit switch. The limit switches cannot be moved once the

actuator is manufactured. While voltage is applied to the

motor power pins, (1 & 2) the actuator extends. Reverse the

polarity and the actuator retracts. This can be accomplished

manually with a DPDT switch or relay, or using an H-Bridge.

The –S model cannot be used with the LAC control board.

Option P – Potentiometer Position Feedback

WIRING: (see last page for pin numbering)

1 - Orange – Feedback Potentiometer negative reference rail

2 - Purple – Feedback Potentiometer wiper

3 - Red – Motor V+ (12V)

4 - Black – Motor V- (Ground)

5 - Yellow – Feedback Potentiometer positive reference rail

-P actuators are suited to automatically controlled positioning

systems, but they can also be driven manually. The –P

actuators have no built in controller, but do provide an analog

position feedback signal that can be input to an external

closed loop controller. While voltage is applied to the motor

power pins, (3 & 4) the actuator extends. Reverse the polarity

and the actuator retracts. This can be accomplished manually

with a DPDT switch or relay, or using an H-Bridge circuit.

Position of the actuator stroke can be monitored by providing

any stable low and high reference voltage on pins 1 & 5, then

reading the position signal on pin 2. The voltage on pin 2 will

vary linearly between the two reference voltages in

proportion to the position of the actuator stroke.

The P16 –P actuator can be used as a linear servo by

connecting the actuator to an external controller such as the

LAC board offered by Actuonix. This control board reads the

position signal from the P16, compares it with your input

control signal then commands the actuator to move via an on-

board H-bridge circuit. The LAC allows any one of the

following control inputs: Analog 0-3.3V or 4-20mA, or Digital

0-5V PWM, 1-2ms Standard RC, or USB. The RC input

effectively transforms your P16 into a linear servo, which is a

direct replacement for any common hobby servo used in RC

toys and robotics. Refer to the LAC datasheet for more

details.
