Paddle Controller

Equipment operators agree that the Laird Technologies Paddle-type controller is perfect for heavy industrial applications. Designed with both operators and maintenance personnel in mind, this heavy-duty controller is ideal for indoor and outdoor use. It is very easy to use, as most of the controls have been modeled after those commonly found in crane cabs. In addition to cranes, the paddle controller can also be used for railroad, military, and other industrial applications.

The Paddle controller uses advanced microcomputer electronics and surface-mount technology. It can be used with all Laird Technologies' AT or MP Series receiver/decoder units and can be utilized with existing systems as either a replacement or spare controller. A variety of synthesized RF transmitter configurations can be provided with this controller providing both licensed and non-licensed radio channels. Laird Technologies' Toggle controller meets all FCC's requirements regarding narrowband and 12.5 kHz band widths.

The Laird Technologies' Paddle controller consists of an encoder circuit board that uses industrial-grade mil-spec digital components, a powerful microcomputer and a sophisticated operating software code. All components are protected by a thick-walled, epoxy-coated extruded aluminum case. The ends of the housing are rubberized metal plates that make shock absorbing end "bumpers."

All Paddle controllers are customer configurable to provide anywhere from 1 to 6 paddle or lever switches, any combination of up to 3 joystick style switches, and push-button and/or toggle switch configurations. In addition, all functions are identified by durable, custom-engraved nameplates. Paddle controllers are field-tested and have been proven under extreme conditions. Total water and dust sealing makes them suitable for indoor and outdoor operation.
