Sdc 400W1-433 Wireless Transmitter 433 Mhz Gate Controller

Product Description

The SDC - SECURITY DOOR CONTROLS 400W1-433 is a wireless transmitter operating at 433 MHz, designed for gate controller and access control applications. It sends radio frequency signals to a compatible receiver or controller, triggering gate operation or entry system responses without hardwired connections between the transmitting device and the control unit. This type of transmitter is typically installed by licensed electricians, low-voltage technicians, or access control specialists working on commercial or residential gate systems.

The 400W1-433 is suited for gate controller installations where wireless triggering is required. It fits into access control setups at facility entrances, parking areas, and secured perimeters where running control wiring is impractical or not permitted. The 433 MHz frequency band is a standard operating range for short- to mid-range wireless access control and gate automation systems.
