1. Sensor (Clamp-in/Snap-in,315MHz/433MHz) is the programmable universal sensor specially built for efficient sensor replacement. It perform like old sensors,in terms of signal interval,durability,and functionality. Featuring a convenient design that allows for quick installation and removal of the sensor,it is truly the ultimate TPMS solution. 2. Sensor(SW2IN1) is a programmable universal sensor specially built to combine both. 315MHz and 433MHz applications in ONE sensor for efficient replacement. 3. Featuring the exclusive press release valve design to allow rubber and metal stems to interchange by hand,without a sensor head fitting tool. Performs like sensor signal interval,durability,and functionality. 4. Sensor(SW2IN1) can replace direct TPMS sensors fitted on wheels, including old equipment and programmable universal sensors. Our Sensors can be programmed to replaced 98% sensors on vehicles today. Sensor(SW2IN1) can be programmed by diagnostic scanner (eg. TS508 TS601 MK808TS MP808TS) to replace to cover over 98% of all sensors on the market. 5. Universal 433MHz 315MHz Metal Stem Sensors offer the latest model vehicle coverage because these TPMS sensors quickly update during installation with an wireless programming tool. Only two sensor types cover 98% of all sensors on the market and are ID clone- with no sensor re-learn required.<br><br>Battery: CR2032 Battery Life: equal 3 years Battery voltage: 3.0 V Low Frequency Inductance/125KHZ PREMO/ 7.2MH/5.89MH Crystal Oscillator/3225 NKD 26MHz Chip USA-NXP-Freescale-FXTH87E Valve Chuangxin Operating Temperature: -45 - +125 Pressure rating: Max support 900Kpa Transmission Power: less than equal 8dBm (5-8dBm) Transmit frequency: 433MHz or 315 MHz Temperature Reading Accuracy: 3C Pressure ding Accuracy: 3 kPa G Sensor Reading Accuracy: 15% Storage temperature: -40C to +150C Colour:black Material:metal+plastic<br><br>Package Contents: 20 x Programmable TPMS Tire Pressure Sensor<br><br>Only the above package content, other products are not included.
