Entel Intrinsically Safe Two-Way Transceiver Radio ATEX

Entel ATEX explosion-proof two-way radios for hazardous industrial environments

The radios operate in the 136-174 MHz VHF or 400-470 MHz UHF bands. Analogue and DMR operation supports gradual migration from existing analogue systems to digital radio networks, while 12.5 kHz digital channel spacing enables efficient spectrum use.

Where can Entel explosion-proof two-way radios be used?

The intrinsically safe design is intended for workplaces where ATEX-compliant radio equipment is required. The operating temperature range is -20 to +55 degrees Celsius, while the construction is designed for dusty, wet and mechanically demanding industrial conditions.

ATEX IIA and IIC protection for Entel ATEX radios

The category includes versions certified to II 2G Ex ib IIA T4 Gb and II 2G Ex ib IIC T4 Gb. IIA versions provide up to 4 W RF output, while IIC versions provide 1 W, so the selected radio must match the ATEX requirements of the site.

What is the difference between VHF and UHF ATEX radios?

VHF versions operate in the 136-174 MHz band, while UHF versions cover 400-470 MHz. The correct frequency band should be selected according to the existing radio system, licensed frequencies and the local RF environment.

DMR digital and analogue operation for industrial radio communication

Dual-mode operation supports continued use of analogue radio systems and migration to DMR communication. Programmable functions, individual and group calls, and monitoring of multiple receive groups are also available.

How does IP68 protection safeguard the Entel handheld radio?

According to the documentation, IP68 protection includes resistance to immersion at a depth of 2 metres for 4 hours. This is particularly important in dusty, wet and outdoor industrial environments.

MIL STD 810 environmental resistance

The radios comply with MIL STD 810 C/D/E/F/G requirements for factors including thermal shock, humidity, shock and vibration, making them suitable for regular mechanical stress in professional use.

Which safety functions are available on an intrinsically safe radio?

Programmable Lone-Worker, Man-Down and emergency button functions are available in digital mode. These functions can initiate an alarm if the user does not respond, falls or manually triggers an emergency alert.

Approved accessories for hazardous-area communication

Only suitable approved accessories may be used to maintain intrinsically safe protection. The lockable, gold-plated accessory connector helps reduce the risk of corrosion and accidental disconnection.
