PS41 系列压力开关
经济的小型压力开关
特性...
- 3.5到100psi (0.24到7bar
概述/设计原则:
PS41系列小型压力开关设计用于空间和/或价格敏感的苛刻场合。采用活塞/隔膜设计，集活塞技术的耐高压和隔膜的灵敏度于一身。采用内六角头螺丝，即可实现现场调节，又可防止人为误动.

* These numbers are for the standard microswitch. With either the -SP or 10A option, the values are typically 20% greater than those listed. With the -RD option, the values will be typically 25% less than those listed. In certain applications, deadband can be tailored and controlled to customer specifications. Consult factory for details.
