Waveguide Switches

Our line of waveguide switches are designed for reliability in outdoor environments including freezing rain, sand, and dust. A mating connector is supplied with each switch.

Power Connectors:
• for WR229 through WR62 - ITT KPTO2614-19P
• for WR42 through WR28 - ITT KPTO2614-10P

Operating Temperature: -40 to +75 °C

Humidity: 100%

Pressure Rating: 20 psig, including driving head

Standard options are available as follows:

• Flanges can be selected from most common North American or metric types. Specify flange type with order.
• Driver voltages include 12V, 24V, or 48V DC and 115V or 220V AC. Specify driver voltage with order.
• Weather cap for manual override control (required for outdoor environments).
• Drive head includes Form C contacts, some of which may be replace with inhibit contacts.
