For the standard version Code S one switching amplifier is required,
For the security version Code T a fail-safe amplifier for each inductive
proximity sensor is required.
Operating mode min. (=low) / max. (=high) selectable by adjustment
of switch vanes.
Operating mode normally closed circuit / normally open circuit selectable
at switch amplifier output.
Contact closed within the positive range.
Contact open within the positive range.
For feedback lever effective length 117.5 mm (4.63 in),
stroke 30 mm (1.28 in) and maximum gain.
For security version: lower temperature limit –40°, and operating location
at a class D2 location. For this version a fail-safe amplifier for each inductive proximity sensor is required, eg Pepperl & Fuchs WE 77/Ex-SH-03

SAFETY REGULATIONS
SWITCHING FUNCTIONS
Explosion protection
The switching functions may be freely selected and set.
The control vanes may be adjusted as desired in order to
reach the wanted switching behavior. The illustration here
shows the four basic settings and adjacent the respective
switch behavior (gray=immersed vane).
The examples are based on the following setting:
Mounting left=feedback level right; transmission is selected
so that at stroke x from 0 to 100 % the guidance shaft
travels through a rotary angle of 180°.
Illustrated in resting position x = 0%.

Type of protection . . . . . . . . II 2 G EEx ib/ia IIB/IIC T4/T6
Certificate of conformity . . . . PTB 02 ATEX 2153 (Option
Limit switch)
For operation in certified intrinsically safe circuits with the
following maximum values:
Umax. . . . . . . . . . . . . . . . . . 16 V
Imax. . . . . . . . . . . . . . . . . . . 25 mA
Pmax. . . . . . . . . . . . . . . . . . 64 mW
Internal inductance . . . . . . 100 µH
Internal capacitance . . . . . 30 nF
The certificate of conformity refers to the inductive sensor
installed. Mounting conforms to the stipulations of the certificate and the mounting conditions.
2-wire technique: If control vane is immersed the initiator
power circuit becomes high-ohmic.
3-wire technique: If control vane is immersed the contact is
closed against plus.
Micro switch: Contact opens during passing of the control
vanes.
