Proximity switch

SP131&SP134 Serie of Proximity Switches

Our switches are designed based on the principle of dry reed switch. When using a permanent magnet to drive a reed switch,the ON-OFF region will vary depending on the type of switch used, its pull-in value and the size and force of the permanent magnet. Soway has the solutions for proximity, level, speed, and flow sensing needs with a broad range of reed switch offerings.

  • Model: SP131 & SP134


Our switches are designed based on the principle of dry reed switch. When using a permanent magnet to drive a reed switch,the sensing distance will be varied base on the type of switch, the size of the permanent magnet. Soway provides proximity switches, liquild level sensors, speed rotate sensors, and flow meters.

  The principle of Magnetic proximity switches is to produce a magnetized zone by changing the position and polarity of trigger so as to make the sensor working. Hermetically sealed, life at least 1 million times, easy installation, customer can define activated distance.
