LEMH/HT Electric Actuator, Low Profile Slider Type, Linear Guide, Single/Double Axis Type, Step Motor (Servo/24 VDC)
The LEM electric actuator family features the lowest table height of all sliders, 40mm or less. Four series are available, including basic, cam follower guide, and single or double axis linear guides. Belt drives permit longer strokes and higher speeds than ball screw sliders. Guided types permit higher workloads than the LEFB or LEL.
- LEMH: Single axis linear guide provides higher moment resistance than LEMC
- LEMHT: Double axis linear guide provides higher moment resistance than LEMH
- LEMH & LEMHT: Body sizes: 25, 32
- LEMH & LEMHT: Table height: 28 mm (25); 37 mm (32)
- LEMH & LEMHT: Maximum stroke: 1000 mm (25) ; 1500 mm (32)
- LEMH & LEMHT: Maximum speed: 2000 mm/s

Controller
The actuator and controller are sold as a package.
(They can be ordered separately.)
Confirm that the combination of the controller
and the actuator is correct.
<Check the following before use.>
q Check the actuator label for model number.
This matches the controller.
w Check Parallel I/O configuration matches
(NPN or PNP).
Actuator
[CE-compliant products]
q
EMC compliance was tested by combining the electric actuator LEM
series and the controller LEC series.
The EMC depends on the configuration of the customer’s control
panel and the relationship with other electrical equipment and wiring.
Therefore, conformity to the EMC directive cannot be certified for SMC
components incorporated into the customer’s equipment under actual
operating conditions. As a result, it is necessary for the customer to
verify conformity to the EMC directive for the machinery and
equipment as a whole.
w
CC-Link direct input type (LECPMJ) is not CE-compliant.
[UL-compliant products]
When conformity to UL is required, the electric actuator and controller
should be used with a UL1310 Class 2 power supply.
