Note: UL-listed models have the -US suffix. The model number for an E3JM Through-beam Sensor ends in “-US” (and not in “-N”). (Example: E3JM-10M4-US). The
model number for an E3JK Through-beam Sensor has “-US” after “-N”. (Example: E3JK-5M1-N-US 2M). Tightening nuts, washers, and rubber bushings are not
provided with these models.
Change: Shape of the E3JM conduit socket
Note, however, that DC-type E3JK SSR Output Models are not UL-listed.
*1. Through-beam Sensors are sold in sets that include both the Emitter and Receiver.
*2. Values in parentheses indicate the sensing distance when using E39-R2 Reflectors.

当今的计算机外部设备，都在追求高速度和高通用性。为了满足用户的需求，以Intel为首的七家公司于1994年推出了USB（Universal Serial Bus，通用串行总线）总线协议，专用于低、中速的计算机外设。目前，USB端口已成为微机主板的标准端口；而在不久的将来，所有的微机外设，包括键盘、鼠标、显示器、打印机、数字相机、扫描仪和游戏柄等等，都将通过USB与主机相连。
