Walker PTT-500M-NC-1-00 Push-to-Talk Black Handset

Walker PTT‑500M‑NC‑1‑00 – Rugged Push‑to‑Talk Handset with Noise Cancellation

The Walker PTT‑500M‑NC‑1‑00 is a professional, heavy‑duty push‑to‑talk (PTT) handset designed for use with two‑way radios, intercom systems, and industrial communication networks. Finished in durable black, this handset features a noise‑canceling microphone and a large, tactile PTT button, ensuring clear, instant voice transmission even in high‑noise environments such as warehouses, loading docks, security checkpoints, and manufacturing floors. Built to withstand drops, vibration, and constant use, the PTT‑500M‑NC‑1‑00 is a reliable replacement or upgrade for existing PTT handsets, delivering years of trouble‑free operation.

How It Works

The PTT‑500M‑NC‑1‑00 connects directly to a compatible two‑way radio base station, intercom system, or dispatch console via a standard modular cord (RJ11 or 4‑pin, depending on configuration). When the user presses and holds the large, glove‑friendly PTT button on the handset, the noise‑canceling microphone is activated, and the system transmits the user’s voice to the selected channel or talk group. Releasing the button returns the device to listen‑only mode. The noise‑canceling electret microphone filters out background noise (e.g., machinery, traffic), while the dynamic receiver provides clear, amplified incoming audio. For a complete communication center, pair this handset with a professional corded headset from FindHeadsets – offering hands‑free monitoring for dispatch staff.

Compatibility & Design

The Walker PTT‑500M‑NC‑1‑00 is compatible with most two‑way radio base stations, intercom systems, and dispatch consoles that accept a standard PTT handset interface (e.g., Motorola, Icom, Kenwood, Vertex, and industrial intercom brands). Check your equipment’s connector type; adapters may be available. The handset is constructed from high‑impact, UV‑stabilized ABS plastic with a reinforced, kink‑resistant coiled cord (approx. 2.5 meters retracted, extending to over 6 meters). The cord is armored against cuts and abrasion. The PTT button is large, tactile, and rated for thousands of cycles. The handset includes a hook switch (for hang‑up detection) and a noise‑canceling microphone with wideband response. It is hearing aid compatible (HAC) and operates from -20°C to 60°C. The housing is IP54 rated for dust and splash resistance. The black finish resists scuffs and blends into professional environments.

Why Choose This Product

Standard telephone handsets are not designed for instantaneous push‑to‑talk communication. The PTT‑500M‑NC‑1‑00 turns any compatible two‑way radio or intercom into an efficient, ergonomic voice tool, reducing training time and improving response speed. The noise-cancelling microphone is critical in noisy industrial environments, ensuring that dispatchers understand every word. The rugged construction outlasts consumer‑grade handsets, lowering the total cost of ownership. The long, reinforced cord allows operators to move within a radius while staying connected. For facility managers, this handset is a direct replacement for worn or damaged PTT units, with simple plug‑and‑play installation (no complex programming). The “NC” designation indicates noise cancellation, a valuable feature for busy dispatch centres.
