RA Series Right Angle Waterproof Feed-Thru Fittings

Route cables at 90° through vertical and horizontal surfaces with wall
hugging low profile design that keeps cable secured close to the surface reducing intrusion with personnel or other equipment / cables.

Molded of nylon, the Sculpted shape has no sharp edges and provides
radiused 90° feed-thru bend in cables without damage.

Easy installation: slide silicone compression rings on cable, mount base piece with waterproof gasket then attach sealing end cap to create an IP 65 waterproof seal. Note cable must be routed without end connector attached.

Three models to accommodate wide range of cable diameters.

Model Cable Diameter Range (Inches) Dimensions (Inches)
RA-1 0.1 - 0.25 2.17 x 1.65 x 0.63
RA-2 0.27 - 0.35 3.23 x 2.44 x 0.95
RA-3 0.39 - 0.47 3.23 x 2.44 x 0.95

 


Emergency Relay/Charger - ERC

The E.R.C. allows emergency battery tie-in to a radio system that is normally operated by a power supply.

Under normal conditions the radio is connected through the ERC to the power supply and the back-up battery receives only a trickle charge to keep it in peak condition.

In the event of AC power failure a relay automatically connects the radio to the back-up battery, restoring the system within one second.When AC power is restored the radio is automatically reconnected to the power supply and the trickle charge resumes to the battery.

Available in 12 or 24 VDC, 15 or 35 Amp ratings, (not ignition protected.)

Application notes:

  • 1 sec. switch over delay may not be suitable for data transceivers. Instead, use a system where
      the battery is floated on output of power supply – see Power Pac or IPS or APS.
  • Trickle charge current will maintain a back-up battery but will not restore a deeply discharged battery.
      A separate high current charging source is required.
