SENSOR SOLUTIONS /// SKH 02/2019 Page 1 Available in both 250 and 400-inch stroke ranges, the SKH linear position sensor is a perfect solution for applications ranging from mobile construction equipment to hydraulic lift tables and anything else in between. The SKH offers compact design, ease of use and the utmost in flexibility. Every unit offers the customer a user-selectable 4-20 mA or 0-10VDC output signal option, an easily adjustable stainless steel mounting bracket for multiple installation options and the ability to change the direction of the electrical connector to accommodate the user’s wiring needs. Our unique electronic circuitry and an extremely durable spring-loaded stainless steel measuring cable deliver an accurate reliable “absolute” position feedback signal over the entire stroke. SKH Cable Actuated Sensor CANOpen Output Signal
FEATURES
Flexibility - Every unit offers linear position up to 400” (10m) providing flexibility to work across a wide range of aerial applications. This off-the-shelf series offers a wide selection of industry standard output signals (4-20mA, 0-10Vdc, CANOpen and J1939 CANbus). Ease of use - A compact design, a stainless-steel mounting bracket for multiple installation options and an easily- adjustable measuring cable orientation make this sensor easy to install and manage. Superior engineering - TE provides engineering partnership to customize for specific applications. There is also an option to have two sensors elements in the same package with no additional space requirement. This provides fail-safe security for aerial applications.
APPLICATIONS
Accurate measurement in customized applications industrial and commercial transportation like: Fork lifts Telescopic arms Boom lifts Scissor lifts

Electrical Connection Field Installable Connector Position Data Overview
SENSOR SOLUTIONS /// SKH 02/2019 Page 5 Internal Controller Board LSS, Baud Rate and Node ID settings: LSS, Baud Rate and Node ID settings are set via dip switch found on the internal controller board. To gain access to the controller board, remove the 4 cover attaching screws and carefully separate the sensor cover from the main body. Be careful not to damage the small gage wires that connect the potentiometer to the controller board mounted directly to the rear cover. Follow the instructions below for desired settings and reinstall sensor cover. LSS Settings: IF DIP Switch 1 is set to “on” position, then LSS will be functional and uses the contents of EEPROM including Node ID and Baud Rate. If DIP Switch 1 is set to “off” position, then DIP switches will override information in EEPROM including the Node ID and Baud Rate. BAUD Rate: If DIP Switch 1 is set to “off” then BAUD rate is set via DIP switch 2 and 3 as shown: Node ID: If DIP Switch 1 is set to “off” then the Node ID is set via DIP switches 4 – 10 as shown below. The DIP switch settings are binary starting with switch number 4 (=20) and ending with switch number 10 (=26). The Node ID is equal to the binary setting.
SENSOR SOLUTIONS /// SKH 02/2019 Page 6 Manufacturer Objects Index Sub-Index Name Default Comment 2000 Raw Position Value This is the averaged, non-scaled value from the encoder. 2001 Emergency Buffer Distance 0.1 Emergency Message is sent when the output of the sensing potentiometer is outside its calibrated range by more than 0.1% of the sensors full measurement range (Emergency Buffer). This allows for non-repeatability of sensor and customers application. This object allows user ability to change buffer size along with transmission of Emergency Message, Manufacturer specific bit in error register set, and error added to error list. Device Profile Area Index Sub-Index Name Default Comment
6000 Operating Parameters 0X0000
6004 Position Value 0 Counts proportional to measuring cable extension. Nominal values are 0x006 with cable fully retracted and 0xFE5 with cable fully extended. Format of data in CAN message is little endian – least significant byte pair first. Therefore 0x008 would be shown as “08 00” and 0xFE5 would be shown as “E5 0F”
