The AJM, AJR and AJS "bellypack" controllers are ergonomic units that can support a wide variety of switches and between 2 to 6 joysticks. This enables countless configuration options in both the "digital-only" version or the version that includes both digital and analog commands. Other features include automatic search for the working frequency at start-up, dual-band radio (434 and 915 MHz), PL d category for the STOP function (EN ISO 13849-1), 2 or 3 position switch, rotational switch, potentiometer, IR Sensor, Zero-G sensor and much more. Thanks to two-way radio communication, receiving units can transfer information about the controlled machine to the transmitting unit and show it on 4 LEDs and/or high performance display with 16 LEDs. A 1.54" display is mounted on the AJS, whereas the AJR and AJM units may also have a 2.7" display, for indoor (OLED display) and outdoor use (transflective display). In both cases, information appears as icons, descriptions or measurements.
