Introduction The Optical Proximity Switches are a reliable solution for automation where other Proximity Switches have limitations. These are Infra-red type sensors incorporating advance and reliable technology. These switches have a distinct advantage of higher sensing distance more...
The unit is a port powered two-channel (half-duplex) RS-485 to RS-232 converter. It converts the balanced halfduplex RS-485 signals to TD and RD RS-232 lines. The unit is powered from the RS-232 data and handshake lines whether the lines are high or low. An external power supply more...
This is a plug and play GSM Modem with a simple to interface serial interface. Use it to send SMS, make and receive calls, and do other GSM operations by controlling it through simple AT commands from micro controllers and computers. It uses the highly popular SIM300 module for amore...
Beam of invisible pulsed modulated infra - red light is produced by emitter. This beam is sensed by receiver at another end (in through beam version) or reflected by object and received by receiver placed near emitter (in diffuse version). When this beam is interrupted by object,more...
