Four-button wireless remote control transmitter (IC PT2262 / SC2262)

Image
There are two types of wireless remote transmitters: electromagnetic waves and infrared. The working distance of the infrared remote transmitter is short, and the infrared ray can only be transmitted through the straight line, and can’t bypass the barrier. RF remote transmitter uses the RF signal, it is transmitted in all directions, and the signal can cross a certain barrier. The electromagnetic wave wireless remote control system uses the transmitter to transmit the electromagnetic wave, and the receiver extracts the electromagnetic wave and triggers various devices. The electromagnetic wave wireless remote control system commonly used in burglar alarm equipment, industrial equipment, doors and windows remote control, car remote control. The following describes a commonly used four-button wireless remote control transmitter, the parameters are as follows: Working voltage: DC12V (23A / 12V battery) Working current: 10mA / 12V Modulation method: ASK Frequency: 315MHz / 433M...

Remote Control Electromagnetic Lock

Image
Electromagnetic lock is a locking device that consists of an electromagnet and an armature plate. The principle behind an electromagnetic lock is the use of electromagnetism to lock a door when energized. Essentially it consists of an electromagnet attracting a conductor with a force large enough to prevent the door from being opened. That is to say, if only we could cut off power supply and make electromagnet force between electromagnet and armature plate to disappear, the door would be opened. Furthermore, we just try to use a direct dc output momentary remote and one button transmitter to cut off electric power to open the door. The following demonstration will show. At first, we prepare material. The wiring When we supply power to electromagnetic lock, electromagnet will attract armature plate through magnetic force. The door is locked. When we press button, the power supply will be cut off. The door is open as soon as electromagnetic lock unlock instantly. What’s more, t...

How to Control 24V Devices

Image
Question from customer: We require an RF remote controller with 2 channel output 24v dc power supply. Then it can be operate nearly 35 meters. Remote controller can operate when we press remote button. When we release the remote button, remote controller will not operate. Answer: We recommend you the model of 2 channel direct power output momentary remote controller   (S2XM-DC24+C-2). The operating voltage is 24V. The working distance is 100m. Direct power output; control Lights, Motors, Fans, electrically operated Doors/Locks/Windows/Blinds/Cars or Other Appliances. You can turn on/off the receiver with transmitter (remote control) from any place within a reliable distance; the wireless RF signal can pass through walls, floors and doors. It is momentary working mode. Momentary mode can be set to control rolling blind or rolling door. You need to press and hold the button of remote to make the blind or door open/close. Momentary mode is motivated by single relay, which means yo...
