compact limit switch cls jack accessories patent pending dimensions circuits 2-bsj msj every motorized worm gear screw jack must be controlled so that power to the motor is turned off and the brake engaged before the limits of mechanical travel are reached the actionjac™ compact limit switch cls senses extension shaft rotation and provides switch contact closures that can be used to control motors the cls is an economical way to detect travel limits and prevent over travel of the worm gear screw jacks the single pole double throw spdt limit switches are useful for limiting the maximum and minimum extension the cls is wired as a normally closed circuit but can easily be wired as a normally open circuit the cls is provided with a standard terminal block for ease of set up the cls limit switches are adjustable in the field with the removal of the easily accessible enclosure cover the cls is designed to accommodate a variety of standard options which include a hall effect potentiometer and reed switch the potentiometer version is used to provide an analog signal for sensing jack position the hall effect sensor and reed switch are used to provide a pulse signal to indicate jack travel the cls has been designed to meet nema 4 standards for dust and water tightness the cls can be provided with a variety of gear ratios to accommodate virtually any travel features • light weight • twelve gear ratios to accommodate most travels • contains two limit switches • simple travel adjustment design • eight different mounting positions • available on 2 ton through 20 ton • optional reed switch hall effect sensor or potentiometer • internal limit switch temperature range from -20° to 150°f • feedback option available switches are factory installed to assure proper assembly in the correct orientation for specified mounting position caution limit switches are not set at the factory switches must be set during installation and prior to use the limit switch assembly will be permanently damaged if allowed to over travel cls is supplied with a plugged access hole for a water-tight connection water-tight connector and sealant should be used 7.7 Ø7 8 5.3 2.0 4.0 2.6 1.0 h 7.08 2.5-bsj msj 7.14 3-bsj 7.08 5-bsj msj 7.90 10 15-bsj msj 8.40 20-bsj msj 8.85 h compact limit switch positions 2 1 4 3 the compact limit switch is not intended to be used as a safety device 5 6 7 8 to order a compact limit switch specify • cls code listed below • mounting position listed on the next page insert the correct designation in the actionjac™ worm gear screw jack reference number see page 31 and 69 for more information on jack reference numbers electrical ratings example dc current — 125 volts spdt .50 amps ac current — 250 volts spdt 11 amps 2.5-bsj-u 6:1/clsh-8/sse-1/ft/24/s position 10-turn potentiometer 10,000 ohm 2 watt examples of compact limit switch designations clss-8 – standard cls w spdt limit switches only position #8 potentiometer standard blue limit switch 2 blue limit switch 2 pink limit switch 1 pink limit switch 1 white white 0 vdcblack sense white clsr-4 – standard cls w spdt limit switches reed switch pos 4 clsh-3 – standard cls w spdt limit switches hall effect pos 3 clsp-1 – standard cls w spdt limit switches potentiometer pos 1 important these designation numbers are not complete part numbers these assemblies contain gear reducers with ratios that vary according to the model and travel of the jack if you are ordering a replacement switch assembly complete information on the jack is required ref vdcred product code switch type feedback clss spdt – clsr spdt reed switch clsh spdt hall effect sensor clsp spdt potentiometer note while the 10-turn potentiometer is rated for 10,000 ohms as implemented in the compact limit switch assembly it can not and should not operate over its full range minimum and maximum resistance values can not be known until the unit is installed and final travel limit adjustments have been made therefore the device connected to the potentiometer should include provisions for trimming to compensate for these values jack accessories product code wiring diagrams pot reed switch hall effect sensor blue limit switch 2 blue limit switch 2 pink limit switch 1 pink limit switch 1 white pulse purple pulse black white 110 vdc or 100 vac .5 amps max 5-10 vdc black pulse purple gnd green 196 nookindustries.com nook precision actuators the specifications and data in this publication are believed to be accurate and reliable however it is the responsibility of the product user to determine the suitability of nook industries products for a specific application while defective products will be replaced without charge if promptly returned no liability is assumed beyond such replacement 197
