Built for Durability and Performance
The S33 is more than a handset—it’s a tough, high-performance tool built for demanding
environments. With MIL-STD-810H certification, it withstands multiple 1.5m drops onto
steel surfaces, and its polycarbonate display lens offers superior durability over glass.
Its health-grade resin and IP54 rating make it resistant to dust, water, and daily cleaning,
making it ideal for environments where hygiene is crucial.
Crystal-Clear Communication AnywhereExceptional voice quality is at the heart of the S33. Equipped with dual microphones and
noise suppression technology, it ensures crystal-clear communication in even the loudest
environments. With Bluetooth 5.1 for wireless headsets and a 3.5mm port for wired
options, workers have the flexibility to move freely while staying connected.
Intuitive Design and Enhanced UsabilityThe slimmest handset in its class, the S33 is comfortable to hold and easy to carry.
Optional belt clips, swivel clips, and holsters enhance portability, ensuring the device is
always within reach. The intuitive interface provides easy access to essential features,
while message waiting indication (MWI), in/out charger notifications, and customizable LED
controls streamline communication and productivity. Differentiating between internal and
external calls reduces confusion and helps workers stay focused.
Rugged, Secure, and Reliable
The S33 combines rugged durability with DECT Forum Step B security, ensuring secure
communications across industries. Its wipe-cleanable surface and resistance to dust,
water, and abrasions make it a dependable choice for challenging environments.
Boosting Productivity with Messaging Features
More than just a phone, the S33 is a productivity tool with advanced messaging
capabilities. It supports alerts and notifications, while its +25% stronger vibration ensures
critical messages aren’t missed, even in noisy settings.
