Sensor mounting accommodates oil suction tube for construction equipment company

Requirement:

A manufacturer of walk behind equipment needed a low oil level indication sensor that mounted inside the oil filter. The unit was required to be rugged, small, accurate, and incorporate and, as added value to the customer, house a suction tube suction tube to draw oil from the filter to feed a 2 stoke engine. The sensors cable positioning after installation was critical and had to be consistent on all units.

Design parameters:

• Dual role – location for an oil feed tube
• Rugged
• Small Size
• Positioning of cable after installation critical
• Easy to install, remove and maintain
• Must withstand extreme vibration

Solution:

A float switch was custom designed in a new moulding which allowed the suction tube to be accommodated. To over come the issue of the cable needing to be placed accurately the sensor body was designed as a push fit into a grommet designed by Gentech.

Design outcome:

• Based around Gentech VS Product Range technology
• Push-fit moulding design saved valuable assembly time and assured accuracy of final position
• Combining the 5mm suction tube saved the manufacturer additional components and assembly elements
• Nitrile compression grommet
• Moulded in Nylon 6.6
• Float made from NBR Rubber
• Cable with Delphi connector.- saves valuable assembly time

Similar applications:

• Customers using 2 stroke engines with oil tank
• Small engine driven construction equipment
• Recreational vehicles
