Versions 3738-20
– Type 3738-20-xxx14xxxxx2xx Electronic Limit Switch
with integrated solenoid valve
The electronic limit switch with integrated solenoid valve form a compact unit together with a pneumatic actuator, which is easy to mount. The 3/2-way or 5/2-way function of the solenoid valve is selected by changing the position of a molded seal.
This version can be mounted directly onto a Pfeiffer
Type 31b Rotary Actuator. The need for additional pneumatic connections is eliminated.
– Type 3738-20-xxx1000xxx200 Electronic Limit Switch
for external solenoid valve
The electronic limit switch for an external solenoid valve allows switching capacities up to max. 18 W at 24 V DC, meaning all common solenoid valves, even the Ex e versions, can be combined with the electronic limit switch

Versions 3738-50
– Type 3738-50-xxx4x00xxx000 Electronic Limit Switch with integrated solenoid valve
The solenoid valve is integrated into the housing of the electronic limit switch. The electronic limit switch and the solenoid valve are powered by the connected FOUNDATION™ fieldbus two-wire cable according to IEC 61158-2.
The electronic limit switch can optionally be fitted with a forced venting function. This function is activated when the solenoid valve is de-energized after the power supply is interrupted, causing the actuator to move the control valve to its fail-safe position.
– Type 3738-50-xxx0x00xxx000 Electronic Limit Switch with external solenoid valve
The electronic limit switch and the external solenoid valve are powered by the connected FOUNDATION™ fieldbus twowire cable according to IEC 61158-2.
