Linear MCS302210 300MHz Gate Safety Edge Transmitter, 109950/302850 Compatible Linear / Multi-Code MCS302210 / 302210 300MHz Gate Safety Edge Transmitter, 109950/302850 Compatible The Model 302210 Gate Safety Edge Transmitter is for adding obstacle sensing for motorized gates or barrier arms. Using a safety edge transmitter is more economical and discrete than the traditional coiled cord connection method. The transmitter mounts directly on the gate or barrier arm and wires to a standard exterior safety edge sensor (a Miller gate edge sensor is recommended). If an obstacle is encountered, the sensor will present a closed circuit across the connecting wires and the 302210 will transmit a message to the receiver signaling entrapment to the gate operator. The operator then stops or reverses the movement of the gate. The 302210 transmitters are supplied in a weather-resistant, fiberglass box. Its circuit board is coated to prevent moisture damage. The enclosure mounts to the gate, door, or barrier arm through sealed interior mounting screws. The Model 302210 is compatible with 300 MHz Multi-Code receivers and Model 109950 and 302850 receiversCompatible with 300 MHz Multi-Code receiversSafety edge transmitterActivates receiver for the stop or reverse entrapmentNo cables or coiled wiresMounting hardware (4 screws) suppliedPower: 9-volt batteryCodes: 1,024 (set by dip switches)RF frequency: 300 MHzDimensions: 4.28" W x 2.875" H x 2.25" D Payments & Returns Policy
