Three / Four Wire DC Switches Series : IS 3D/ 4D
These are three / four wire switches (+ ve, -ve and output) working on 10-30 v DC, and directly drives DC Relay. Theses switches are compatible with PLC modules because of its insignificant leakage current (50 ฮผ A max) DC switches are divided into two categories according to load connection
- Load connected between supply wire and output wire : ( NPN )
- Load connected between ground wire and output wire : (PNP)
Entire range is available with NO or NC Logic. Special switches with change-over logic are also available. DC switches are protected against overload, short circuit and wrong polarity connection. Special switches with high operating frequency are available for applications of speed sensing. Special protection incorporated within the switch against back EMF from inductive load like relay.
Namur Sensor / Two Wire DC Proximity Switches Type : IS 2D
Two Wire AC Proximity Switches Type : IS 2A
AC Switches operated on 90 โ 230 V AC and directly drive load like contactor or solenoid coil. Low voltage drop of 6 V across the switch makes it suitable to connect even two switches in series. Special protection against spurious signals is incorporated.
Supply voltage | 90 โ 230 VAC |
Load Current | 150 โ 200 mA suitable to drive siemens size โOโ connector or equivalent load. Special switches with load current of of 500 mA are also available in two wire version. Load current for Three Wire Proximity switch is 500 mA |
Operated Frequency | 5 Hz |
