MAGNETIC PROXIMITY SWITCHES

MAGNETIC PROXIMITY SWITCHES


A Wide Variety of Types Available to Meet Applications/Specifications:
  • General Purpose, High Temperature, etc.
  • Two-Wire Systems, Offering a Wide Power Range (1v 1mA to 240VAC 1a)
Features
  1. Completely sealed construction makes this switch best suited for adverse environments.
  2. Direct control of loads of even 100VDC or greater, requiring no power supply or amplifying relay.
  3. No protective R-C snubber/surge circuitry is required for long wiring distances or inductive load.
  4. Eliminates the possibility of erroneous operation and breakdown due to noise or surge.
  5. The contactless design assures a long service life and maintenance free operation.
  6. Economical proximity ...

Separate Type High-Temp.-Use (PSMS-H, T)

(2)
Designed for High Temperature, High Humidity Atmosphere; Best among Non-Contact Types. Assuring 130C for Continuous Duty or 180 C for Short Time

Typical Applications

Continuous casting machines, coke ovens.converters, rolling mills, cement curing ovens, refrigerator's internal equipment.

Influence of Ambient Temperature, and Compensation

Where temperature varies widely from the beginning and dur ing operation, the actuating point and return point may change somewhat due to thermal characteristic of the magnetic unit.
For applications requiring higher accuracy, make the compen sation first before mounting.

As for ratings and specifications other than those below, refer to ...
