    Configuration Options

    GSM Series Configuration Options A-F

    AA = GSM Actuator Size (nominal)
    BB = Stroke Length
    CC = Screw Lead
    D = Connections
    E = Mounting
    F = Rod End Thread / Rod Material

    GGG = Feedback Type

    Your choice of drive will dictate the appropriate feedback device for your situation. Options for feedback type include an array of absolute, analog and incremental encoders, as well as custom feedback alternatives.

    HHH = Motor Stator

    Motor Stator options are described with a 3-digit code. The first digit calls out the stack length, the second digit designates the rated bus voltage, and the third digit identifies the number of poles. Please refer to the mechanical/electrical specifications for motor torque and actuator rated force.

    Motor Stators (all 8 Pole and Class 180H)

    1A8 = 1 stack, 24 VDC *
    1B8 = 1 stack, 48 VDC *
    1C8 = 1 stack, 120 VDC *
    118 = 1 stack, 115 VRMS
    138 = 1 stack, 230 VRMS

    * Low voltage stators may be limited to less than catalog rated torque and/or speed. Please contact your local sales representative when ordering this option.

    II = Motor Speed

    All Exlar T-LAM™ motors and actuators have a standard motor speed designator (described below). The designator represents the standard base speed of the motor for the selected bus voltage.

    Designator Base SpeedActuator/Motor Series
    -505000 rpmGSM20
    -303000 rpmGSM30, GSM40
    -01 … -99 Specialized speed *

    Note: It is not possible to produce every possible speed for each motor at each voltage. *

    Mechanical Options

    PF = Preloaded Follower

    This is a true zero-backlash follower. The dynamic load rating of the zero-backlash preloaded screw is 63% and the calculated travel life is 25% of that required for the same size and lead of a non-preloaded screw. Not available with the LT linear feedback option.

    AR = External Anti-rotate Assembly

    This assembly restricts the actuator output rod from rotating when the load is not held by another method. Shorter actuators have a single anti-rotation mechanism; longer lengths have a mechanism on both sides.

    RB = Rear Electric Brake

    This is a rear, internal holding brake. The rear brake is spring activated and electrically released.

    HW = Manual Drive – Handwheel

    A manual drive handwheel installed on the side of the actuator. Includes an engage/disengage lever that controls an interrupt switch. This lever is not tied to the motor and must be engaged/disengaged, before operating the motor. Not available on all products and may not be available with a holding brake. *

    PB = Protective Bellows

    An accordion-style bellows that safeguards the main actuator rod from damage due to abrasives or other contaminants in the operating environment. The bellows is made of S2 Neoprene coated nylon with sewn construction. Rated for -40 to 250 degrees F (-40 to 121 C). Not available with the extended tie rod mounting option. *

    SR = Splined Main Rod

    A ball spline shafting main rod with a ball spline nut that replaces the standard front seal and bushing assembly. This rod restricts rotation without the need for an external mechanism. The rod diameter will be the closest metric equivalent to our standard rod sizes. Since this option is NOT sealed, it is not suitable for environments in which contaminants may enter the actuator.

    Note: Adding this option affects the overall length and mounting dimensions.

    L1, L2, L3 = Adjustable External Travel Switch(es)

    External travel switches indicate travel to the controller and are adjustable for either the home or end position.

    * Some options are not available with every configuration. For options or specials not listed above or for extended temperature operation, please consult Exlar Applications Engineering.

    Mechanical Options

    NI = Non-incendive Construction (required for Class I Div 2)

    Construction of equipment that, under normal operating conditions, is not capable, due to arcing or thermal effects, of igniting the flammable gas-, vapor-, or dust-air mixture.

    PF = Preloaded Follower

    This is a true zero-backlash follower. The dynamic load rating of the zero-backlash preloaded screw is 63% and the calculated travel life is 25% of that required for the same size and lead of a non-preloaded screw. Not available with the LT linear feedback option.

    This is a rear, internal holding brake. The rear brake is spring activated and electrically released.

    RD = Manual Drive – Simple Rear

    This option provides a hex shaft at the rear of the actuator for manual operation. The hex shaft is directly coupled to the motor and can be turned by hand with a compatible wrench. The hex shaft is enclosed by a sealed cap during operation. This option is not available w/absolute feedback. If the application requires a brake, discuss manual drive use with your local sales representative.

    SD = Manual Drive – Side Hex

    A manually operated side hex shaft installed at the rear of the actuator. The hex shaft is directly coupled to the motor and can be turned by hand using a compatible wrench. The hex shaft is sealed with a cap during operation. This option may not be available with a holding brake. *

    Note: Adding this option affects the overall length and mounting dimensions.

    XT = High-Temperature Protective Bellows

    The high-temperature protective bellows (an XT option) shields the main actuator rod from damage due to abrasives or other contaminants in the operating environment. The bellows is made of D1 Teflon coated fiberglass with sewn construction. Rated for -67 degrees to 500 degrees F (-67 to 260 C). Note: This option is not available with the extended tie rod mounting option.*

    Note: The XT designation is used to specify several different special travel options. When ordering, it is important to describe, in detail, the specific XT option(s) that you need.

    XT = Angular Contact Bearings

    Angular contact ball bearings use asymmetric races through which an axial load passes in a straight line. Therefore, the angle of contact on the inner race is the same as that on the outer race.*

    Note: The XT designation is used to specify several different special travel options. When ordering, it is important to describe, in detail, the specific XT option(s) that you need.

    XL = Special (Non-Standard) Lubrication

    The XL option in the model number specifies some form of lubrication other than the standard provided by Exlar®, which is Mobilith SHC220. Special lubricants include other greases, such as JAX FG-2 food grade or Mobilgrease 28. Another non-standard option is oil cooling.*

    XM = Special Motor Option

    Special Motor Options should be listed as XM and must be approved by Exlar.*
