Product Description
Mx41-730x Series Spring Return SmartX Actuators are available with
Two Position 24 Vac/Vdc, Two Position 100…230 Vac, and 2…10 Vdc
input signal applications. It is possible to field configure the 2…10
Vdc input signal models for other input signals such as floating and
pulse width modulating (PWM).
Features
• 270 lb-in (30 N-m) of torque with mechanical spring return, manual override,
and Brushless DC Motor.
• Stall protected throughout rotation and reversible mounting.
• Models for Two Position 24 Vac/Vdc, and Two Position 100…230 Vac
applications.
• Models for 2…10 Vdc input signal applications (field configurable for other input
signals) with a position feedback signal and direct/reverse acting control mode
selection switch on both sides.
• Models for auxiliary switch applications.
• Models for NEMA 4 / IP66 outdoor applications.
• Direct mount to ½”…¾” round or ½”…11/16” square damper shafts or to
¾”…1.05” round with the field removal of a clamp insert.
• 95° of rotation, adjustable with mechanical end stops and graduated position
indicator showing 0°…95°.
• Can be double-mounted (gang mounting) to accommodate high torque
application requirements.
• 5 Year warranty.
