Industrial radio remote controls · Radio band and frequency management, channels, range, output power rules, battery type and life, operating temperature, enclosure, controls and functional safety
A handheld transmitter is the operator's unit of a radio remote control: it turns button and joystick commands into encoded radio signals for a receiver on a crane, hoist or mobile machine. Settle three things before asking for quotes: the radio band and how the system avoids conflicts with other radios on site, the controls, range and safety functions the machine needs, and the battery, enclosure and temperature range for the working environment.
Handheld and belly-box transmitters for industrial radio remote controls of cranes, hoists, construction and mobile machines, with their batteries and chargers. Receivers sold alone, consumer remote controls, two-way voice radios, robot teach pendants and wired pendant stations are outside this page; two-way radios and teach pendants have their own pages.
01
HBC-radiomatic notes that a large number of radio controls working at once on a construction site or in a factory can conflict on the same channels and shut the control down. Its radiomatic AFS (automatic frequency selection) checks on switch-on whether the last channel is free and otherwise moves to a free one; the operator restarts the transmitter to re-select. Adaptive frequency hopping comes as standard on all its 2.4 GHz systems and needs no manual coordination, and HBC states the 2.4 GHz technology is licence-free in the countries where its systems are approved. Its DECT option offers fully automatic frequency management, high-speed data for feedback and long range. [1]
In the United States, 47 CFR 15.247 governs the 2400–2483.5 MHz band: frequency-hopping systems there must use at least 15 channels, with average occupancy on any channel of no more than 0.4 s within 0.4 s times the number of channels; peak conducted output may reach 1 W for systems using at least 75 non-overlapping hopping channels and 0.125 W for other hopping systems, and 1 W for digitally modulated systems. [3]
Editorial calculation: a 15-channel hopping system may occupy any one channel for at most 0.4 s in each 15 × 0.4 = 6 s period. [3]
Give the supplier the machine and functions to control (motions, speeds, auxiliary functions), control type (push-buttons, joysticks, belly box), radio band and approvals needed in your countries, number of systems on site, range, feedback display needs, stop and start functions with required safety performance, battery type and run time, operating temperature, enclosure protection and drop resistance, and quantity.

HBC-radiomatic states that its Li-ion exchange batteries reach around 500 charge cycles with proper handling and remain usable afterwards at slightly reduced capacity, that less capacity is available below −20 °C and above +70 °C, that they should be charged only with the matching HBC charger at 0–45 °C, and that a 30–50% charge is best for storage. [2]
Editorial calculation: at one full charge cycle per working day and 250 working days a year, 500 cycles is about two years before the battery shows reduced capacity; plan spare exchange batteries and chargers for multi-shift operation. [2]

Tele Radio's Tiger G2 page is a second maker's published range of handheld pushbutton transmitters. It describes the system as SIL3 and PLe certified, with the STOP function and two designated receiver relays approved to SIL3 under IEC 61508 and to PLe, and lists frequency hopping that changes frequency within a spectrum every 40 milliseconds. The figures it publishes are set out below. [4]
The pushbutton transmitters are offered in 433 MHz and 915 MHz versions, for example the TG-T9-1 (433 MHz) and TG-T9-11 (915 MHz) with 8 two-step buttons, and the TG-T11-5 and TG-T11-15 with 12 two-step buttons; some models add a display that shows feedback from the machine. Batteries are rechargeable and replaceable, or rechargeable and internal, depending on model. [4]
In the United States the 915 MHz versions fall in the 902–928 MHz band of 47 CFR 15.247, where a frequency-hopping system with a 20 dB hopping-channel bandwidth below 250 kHz must use at least 50 hopping frequencies with average occupancy of no more than 0.4 s within a 20 s period, and peak output is 1 W with at least 50 hopping channels or 0.25 W with 25 to 49. Ask the supplier which of these cases its radio is certified under. [3]
Editorial calculation: a hop every 40 ms is 1 / 0.040 = 25 frequency changes per second. [4]
