Miller Edge MT21 Monitored Armored Door Electric Edge

The Miller Edge MT21 Monitored Electric Edge is a rugged, touch-sensitive signaling device designed to detect contact and trigger a stop or reverse function in commercial rolling doors and material handling systems. This model is equipped with a Armored durable vinyl jacket and configured for monitored operation using 2-wire, 10K/8.2K resistor, diode-capacitor, or 4-wire setups, making it fully compatible with UL 325-compliant door operators. The MT21 features a patented Alumaglas contact element for consistent performance, along with a flexible PVC body that conforms to floor irregularities to maintain seal integrity.

The MT21 is custom-made to your specifications, including length and wire outlet location (left, right, or universal). Its sealed construction prevents dust and debris intrusion and includes trim-to-fit end flaps for a tight fit. This model is ideal for industrial applications requiring enhanced safety and integration into monitored systems.
