Voltage divider circuit consisted by potentiometers

Nylon coated stainless steel wire

Compact-size for easy to design and installation

High strength plastic housing for using in rough environments

DWSMini is draw wire distance sensor that mount high precise potentiometer with compact-size outer housing. DWSmini is mainly applied for sensing and measuring length of outrigger of heavy equipments and special vehicles by its compact-size, waterproof and high strength housing design. CANopen protocol now available : constitute CAN network with length sensors for outrigger of mobile vehicle.

Length Conversion Formula

Length = (measurement voltage - Min voltage) x gain
- Gain (m/V)
  = Max Length / (Max Voltage - Min Voltage)
- Max voltage
  = Reference Max voltage x (applied voltage V / 5V)
- Min voltage
  = Min reference voltage x (applied voltage V / 5V)
- Max reference voltage
  = Max voltage when 5V is applied
- Min reference voltage
  = Min voltage when 5V is applied
- Max length = Max fetch length

Code format
: DWSMini-[①]-[②]-[③]-[④]-[⑤]-[⑥]-[⑦]-[⑧]-[⑨]

e.g. DWSMini-15-L-CO-0x04
DWSMini-30-D-R-CO-DI-X-3090-F-0x03

If CANOpen output format is selected, options from ⑤ to ⑨ are available.

The direction code identifies the wire drawing direction when the product is attached from the front.

Options

Plug Harness : Delphi 1216-2833

Notes

DWS is designed for operating at low speed wire drawing condition. It may behind its durability if high speed drawing is repeated.

Immoderate drawing may cause damages of internal spring and wire.

Check wiring connections before use.

12 months warranty is provided after released. Warranty provided only in case of using for designed purpose correctly.

Specifications, design and components can be changed without prior notice to improve its performances.
