Pneumatic Indicators and GaugesContents
Pneumatic Indicators andGaugesFesto offers a variety of pneumatically and electri-cally actuated visual indicators:
The pneumatic indicators include in-line and panelmounted designs as well as a multi-pin indicator, allof which simplify monitoring of pneumatic controlsystem operating conditions.
Festo also offers a range of LED indicator solenoidinserts and gaskets that can be easily installed onsolenoid actuated valves to provide ON status indi-cation and simplify troubleshooting.
For applications requiring gauges, conventionalthreaded connector designs as well as panelmounted versions are available, with pressureranges from 0 to 240 psi. Vacuum gauges withranges from 29.6 in HG to 131 psi are also avail-able.

With built-in protective spark arrestingcircuitType MCLZ-24
The insert is installed between thesolenoid and plug. When power is applied,the yellow LED comes on. The DC designcannot be connected with incorrectpolarity.
The protective circuit in Type MCLZ-24protects switch contacts against inductivevoltage peaks when loads are switchedoff.
Note: The seal between the solenoid andplug must be removed when an indicatorinsert is installed. With the seal removedthe degree of protection becomes IP 40.
