拨码开关作为需要手动操作的一种微型开关,在通讯,安防等诸多设备产品上广泛应用。大部分拨码开关采用直插式(DIP),在两态之间变换,再根据不同的位组成2的N次方的不同状态,实现不同的功能。其实细分下来,还有很多种,下面介绍一些具体的系列。
1.半间距型
它的脚距是正常拨码开关的一半,也就是Pitch 1.27mm。主要特点体积小,在线路板上占更少的空间。适宜使用在微型精密的设备上。如:KE系列的KE08RTGT 具体参数及尺寸如下:
SPECIFICATIONS Electrical Ratings Switch: 25mA @ 24VDC Carry: 100mA @ 24VDC Electrical Life 2,000 cycles typical Contact Resistance < 25 mΩ initial Actuation Force 500 gF max Actuator Travel 0.65 mm Dielectric Strength 500Vrms min Insulation Resistance > 100MΩ min Operating Temperature -40°C to 85°C Storage Temperature -40°C to 85°C 2.DIP平型
脚距为2.54mm,采用顶拨直插式(DIP)、平型,属于两态。执行机构的力度在各系列中最大至800gF,外壳、执行机构均采用PBT,UL94V-0材质。触点及端点均镀金,可靠性强。工作温度在-40至85度,适于工业级。如:KG系列的KG02E 具体参数及尺寸如下:
SPECIFICATIONS Electrical Ratings Switch: 25mA @ 24VDC Carry: 100mA @ 24VDC Electrical Life 2,000 cycles typical Contact Resistance < 25 mΩ initial Actuation Force 800 gF max Actuator Travel 2.0 mm Dielectric Strength 500Vrms min Insulation Resistance > 100MΩ min Operating Temperature Storage Temperature -40°C to 85°C -40°C to 85°C 3.DIP滑动型
脚间距Pitch 2.54mm,滑动性直插式开关,属两态。比起KG系列,它的执行机构的力度只有其一半。执行机构为4/6Nylon,UL94V-0,White;外罩材质为PPS,UL94V-0,Black.同样是镀金触点,温度范围-40至85度,适于工业级。如:KL系列KL02EHT 具体参数及尺寸如下:
SPECIFICATIONS Electrical Ratings Switch: 25mA @ 24VDC Carry: 100mA @ 24VDC Electrical Life 2,000 cycles typical Contact Resistance < 25 mΩ initial Actuation Force 400 gF max Actuator Travel 2.0 mm Dielectric Strength 500Vrms min Insulation Resistance > 100MΩ min Operating Temperature Storage Temperature -40°C to 85°C -40°C to 85°C 4.DIP琴键型
脚间距 Pitch 2.54mm,顶拨直插式(DIP),两态,琴键型。执行机构的凸出部分仅为0.9mm。镀金接点,可靠性强。执行机构行程仅为0.9mm,执行机构及外罩材质均为Nylon,UL94V-0.温度范围同样是适于工业级。如:KT系列的KT08RTH 具体参数及尺寸如下:
SPECIFICATIONS Electrical Ratings Switch: 25mA @ 24VDC Carry: 100mA @ 24VDC Electrical Life 2,000 cycles typical Contact Resistance < 25 mΩ initial Actuation Force 600 gF max Actuator Travel 0.90 mm Dielectric Strength 500Vrms min Insulation Resistance > 100MΩ min Operating Temperature Storage Temperature -40°C to 85°C -40°C to 85°C 5.DIP超薄滑动型
脚间距 Pitch 2.54mm,顶拨直插式(DIP),两态,滑动型。镀金接点,可靠性强。执行机构及外罩材质均为6T Nylon, UL94V-0。厚度超薄仅3.7mm,执行机构厚度也仅为0.6mm,适于精密仪器中使用。如:KJ系列的KJ04RTH 具体参数及尺寸如下:
SPECIFICATIONS Electrical Ratings Switch: 25mA @ 24VDC Carry: 100mA @ 24VDC Electrical Life 2,000 cycles typical Contact Resistance < 25 mΩ initial Actuation Force 600 gF max Actuator Travel 0.90 mm Dielectric Strength 500Vrms min Insulation Resistance > 100MΩ min Operating Temperature Storage Temperature -40°C to 85°C -40°C to 85°C 6.DIP琴键凸型
脚间距 Pitch 2.54mm,顶拨直插式(DIP),两态,琴键型。接点部分为镀金接点,通过动作的自清洁构造,确保了高可靠性。执行机构材质4/6 Nylon, UL94V-0,为凸型。外罩材质PPS, UL94V-0。它的宽度和厚度分别为10.7mm、9.5mm,相比其它几个系列比较大。适用于上下操作设备。
如:KP02E 具体参数及尺寸如下:
SPECIFICATIONS Electrical Ratings Switch: 25mA @ 24VDC Carry: 100mA @ 24VDC Electrical Life 2,000 cycles typical Contact Resistance < 25 mΩ initial Actuation Force 400 gF max Actuator Travel 2.0 mm Dielectric Strength 500Vrms min Insulation Resistance > 100MΩ min Operating Temperature Storage Temperature -40°C to 85°C -40°C to 85°C 以上分类基于RIVERSUN (HONG KONG) LTD
