Frequency Hopping RF Transceiver
  The Flex EX2 system automatically search and lock onto
  a free and uninterrupted channel at every system startup or
  during operation when encountering radio interference. The
  system is also capable of two-way communication between
  the transmitter and receiver and as well as receiver to
  receiver with status feedbacks (e.g. MAIN relays, output
  relays, inputs from external sources, and receiver fault
  detection).

Programmable Transmitter Access Card (TAC)

The optional transmitter access card feature (TAC) further guard against any unauthorized personnel from operating the system. The TAC can also be individually programmed unlocking any specific function or functions on the transmitter allowing a more experienced or qualified user to operate, such as the magnet lift, tandem operation, entering restricted areas, etc... The TAC is based on the RFID technology so any industry standard RFID cards or chips can be programmed into the transmitter, such as the commonly used employee RFID badges.

Zero-G Sensor Imbedded
The transmitter is embedded with a Zero-G sensor to guard against any unintended control of the crane or equipment when transmitter is thrown or dropped. When triggered, the entire system will shut down with exception of the horn function (programmable).

Wireless Remote Pairing Function
System information can be transferred wirelessly between two transmitters or between a transmitter and a receiver without the hassle of resetting the spares.

InfraredStartup & System Programming
All Flex EX2 transmitters and receivers are standard-equipped with infrared sensors for infrared system startup option and system wireless programming.

Advanced Controls
The system utilizes dual advanced microprocessor controls with 32bit CRC and Hamming Code, providing ultra fast, safe, precise and error-free encoding and decoding.

Ultra Reliable Pushbuttons
The in-house designed pushbuttons have gold plated contacts and are rated for more than two million press cycles. The defined snap-action steps provide positive tactile feedback even wearing gloves.

Ultra Durable & Rugged Enclosures
The transmitter and receiver enclosures are made from industrial strength nylon and fiberglass composite material, not ABS plastic. All housings meet the IP66/NEMA4 requirements and are highly resistant to dirt, liquid, acid, alkali, grease and oil

penetration. The receiver enclosures and output cables are UL94-V0 rated. 

Compact & Lightweight
The ergonomically designed transmitter and receiver enclosures are extremely compact and lightweight for easy operation and installation.

Unique Mounting Bracket
The removable receiver mounting brackets are uniquely designed for easy mounting and dismounting.

The transmitter requires only two "AA" alkaline batteries with more than 150 hours of uninterrupted operation between replacements. If rechargeable method is preferred, any off-the-shelf high capacity Ni-MH rechargeable batteries can be used in conjunction with the in-house designed wired and wireless charging stations, fully interchangeable.

Abundant Programmable Functions
All functions and settings are easily set via pushbuttons, dipswitches, jumpers, and in-house designed programmer unit. Customized functions can also be added upon request.

Full Systems Compatibility
The software and hardware are fully compatible regardless of model type, minimizing spare parts inventory. The transmitters are also backward compatible with all EX Gen1 receivers.

Labels & Accessories
Flex EX2 system is standard-equipped with pushbutton labels, waist belt, vinyl casing, receiver mounting bracket and output cable. Magnet mount, belt clip, lanyard, rubber guards, miniature indicator light & buzzer, charging stations and TAC are optional.
