Thank you for your interest and su pport in our products. The modification described below has been made to our LAM1 and LAK2LR series. Product Range: Linear actuator Modified Models: LAM1 series and LAK2LR series Description of Modification: The external limit switches used in LAM1 series and LAK2LR series have been changed from glass limit switches to electric limit switches. Before Modification After Modification Linear actuator type LAM1-X-1-XXX-24X LAM1-X-2-XXX-24X Applicable controller LAK2LR-X-XXX-XX LAK2LN-X-XXX-XX Applicable keypad LAP1-X-X Limit switch type Glass limit switch Electric limit switch Output type Normally open Normally closed Normally open Normally closed Operating voltage DC/AC 5~110V DC 10~26V Operating current 30mA(max) 100mA(max) Internal voltage drop 2.5V 4.5V 4V Ambient temperature -10℃℃~70 -10℃~70℃ *If you are not using controller from HIWIN MIKROSYSTEM, please install current-limiting resistor. For selecting suitable current-limiting resistor, please refer to our user manual. Reason of Modification: The external limit switches used in LAM1 series and LAK2LR series have been changed from glass limit switches to electric limit switches, since the glass limit switch is not available to the market anymore. Actuator LAM1-X-2 (with electric limit switches) must be used with controller LAK2LN and is not compatible with controller LAK2LR. This change does not affect the dimensions or property of the mentioned product. For repeat order of actuator with glass limit switches, please contact your local distributor to check the inventory first. If needed, we will assist you in finding substitute product. If you have any question, please contact your local distributor. Implementation Date: Dec 23, 2019 Sincerely, HIWIN MIKROSYSTEM CORP.
