Head and Cap Mounted - EPS Proximity Switch
Brand: Schrader BellowsEPS Inductive Switches are suitable for general industrial as well as automotive applications requiring weld field immunity.
- EPS-7: Economical, General Purpose, 2 wire device, primarily for AC applications. (Not suitable for 3 wire 24 volt Sinking or Sourcing applications.) Also for automotive industry applications.
- EPS-6: Economical General Purpose, 3 wire, DC sensor, dual output: sinking and sourcing.
Series and Parallel Wiring
When Schrader Bellows EPS-6 or 7 proximity switches are used as inputs to programmable controllers the preferred practice is to connect each switch to a separate input channel of the PLC.
Series or parallel operations may then be accomplished by the internal PLC programming.
EPS-6 or 7 switches may be hard wired for series operation, but the voltage drop through the switches (see specifications) must not reduce the available voltage below what is needed to actuate the load.
EPS-6 or 7 switches may also be hard wired for parallel operation. However, the leakage current of each switch will pass through the load.
The total of all leakage currents must not exceed the current required to actuate the load.
When wiring EPS-6 sensors in parallel it is recommended that decoupling diodes be used.
Minimum Stroke
The minimum stroke for EPS-6 or 7 and CLS-1 or 4 sensors, utilizing standard components, is the cushion sleeve or spear length for the cylinder series in which the sensor is installed.
See the individual Industrial Cylinder series catalog for cushion length details. Contact the factory if a shorter stroke is required.
EPS proximity switches may be ordered on PA-2, PL-2, PH-2, PH-3 and SHM Series cylinders.
Mounting styles MT1, MT2, ME5, MF1 and MF2 should be used with caution because of possible mounting interferences.
Features- Fixed mount design is actuated by proximity (without contact) of cushion sleeve or spear
- Provide an end-of-stroke signal with or without functional cushion
- Available up to 10.00" bore PA-2 Series and 8.00" bore PL-2 & PH-2 Series
