CR9440 系列是磁力操作限位或接近传感器系列，用于运动部件之间不可能或不需要物理接触的场合。它们的外壳符合 CSA I 类 C 和 D 组和 II 类 F 和 G 组危险场所的额定值。
CR9440-QS2 磁探测器限位传感器包含一个封装的速动触点元件。当置于磁场中时，此触点将关闭。
CR9440-QST2 Traic 磁性接近传感器具有 NO Triac 电路，当传感器置于磁场中时该电路会导通。当磁场充分减小或移除时，电路恢复到不导电状态。
• 易于维护——无需进行电气或机械调整。
• 紧凑型设计 - CR9440-QS2 磁力限位传感器只有 4-9/16" 长 X 3/4" 直径。
• CSA 批准用于危险场所应用。
• 可靠性——环氧树脂封装可防止潮湿、灰尘和腐蚀剂。
• 快速操作 - 1 毫秒操作时间高达 400 赫兹。
• 低温运行 - CR9440-QS2 低至 -65°C，CR9440-QST2 低至 -40°C。
• 通用电气 CR115X2 兼容替代品。
The CR9440 series is our line of magnetically operated limit [or] proximity switches utilized where physical contact between moving parts is impossible [or] undesirable. Their enclosures meet the ratings for CSA Class I Groups C & D [and] Class II Groups F & G hazardous locations.
The CR9440-QS2 Magnetector Limit Switch incorporates an encapsulated snap-action contact element. This contact will close when placed in a magnetic field.
The CR9440-QST2 Traic Magnetic Proximity Switch has a N.O. Triac Circuit which becomes conducting when the switch is placed in a magnetic field. The circuit reverts to non-conducting when the magnetic field is sufficiently reduced [or] removed.
• Easy to maintain-no electrical [or] mechanical adjustments necessary.
• Compact design - the CR9440-QS2 Magnetector Limit Switch is only 4-9/16" long X 3/4" diameter.
• CSA Approved for hazardous location applications.
• Reliability-epoxy encapsulation protects against moisture, dust [and] corrosive agents.
• Fast operation - 1 millisecond operating time up to 400 Hz.
• Low temperature operation - down to -65°C for the CR9440-QS2 [and] -40°C for the CR9440-QST2.
• General Electric CR115X2 compatible alternative.
