DESCRIPTION Greenco’s
Reed Switch consists of a hermetically sealed glass capsule
containing two cantilevered ferromagnetic blades. The blades come
together and close the electrical circuit whenever the magnet,
mounted on the piston, passes under the response area of the switch.
An integral arc suppressing resistor-capacitor circuit protects
blade contacts from voltage spikes, thereby extending cycle life.
The lead wires are shielded to protect against sending or receiving
induced currents as false signals. The shield may be “drained” using
un-insulated third wire. An ohmmeter is recommended to test the
switch function. DO NOT USE an incandescent light bulb as high
in-rush may damage the switch. Be sure to connect the reed switch to
the power source through a load. Direct connection of the switch may
cause damage to the internal elements of the switch. To prevent
electric shock, always shut off power supply before handling
electric wire leads. The comprehensive design of the cylinder barrel
thickness and mass of magnet, coupled with low profile switch
provides sensitivity, dependability, repeatability and desired
response time. PROXIMITY and GO® switches also available. Contact
factory for additional information.

LINEAR BEARINGS FORTHE TRAC-TROL ® TROLLEY
The Trac-trol ® trolley contains four independent
linear bearings for maximum load bearing capabilities. Each standard
bearing contains a set of continuously re-circulating precision
steel balls for low friction and superior wear resistance. The load
is actually being rolled freely along the two hardened steel guide
rods. Optional stainless steel guide rods and self lubricating
polymeric linear bearings are also available (consult factory.)

20C REPAIR KIT
The 20C repair kit consists of two cable subassemblies and all the
seals for any one model of Cable-Trol ® or Trac-Trol ® cylinder.
When ordering you must specify the complete model number and serial
number of the unit the repair kit is to be used on. |
