ST Grounded Probe Switch
The touch switch is a highly reliable AC solid state presence sensor designed for precise
conductivity sensing. Applications include high temperature environment, light conductive,
aggressive mechanical and chemical environments that targets positive end-point sensing. All
models have a visible neon pilot light to indicate operation of the switch.
Features
• Housings - zinc die cast
• Solid state - no moving parts
• 115 Vac completely self-contained
• Probes up to 10 feet long
• High current output - no relay required for most applications
• Fast response - no warm-up time
• 0.5" NPT conduit entrance
• UL Recognized
Operation
The switch is actuated when a conductive path between probe terminal and ground (1 M
less) is established. The electrical contact to ground operates the switching thyristor. Internal
RC snubber and varistor provide effective protection from typical transients. Normal open
models have a 10 millisecond (maximum) turn on time. Different off delay times are offered in
order that the design engineer may compensate for relay chatter when the probe is subjected
to “bounce” from irregular contact with the grounded metal point of contact.
NOTE: For isolated circuits where the ground is not common - the switch ground terminal
should be connected to the neutral. The metal target to be detected by the probe should then
be wired also to the neutral.
Probe characteristics
The probe terminal is an 8-32 stud protruding from the center of the head. Extensions may be
any electrically conductive wire or material suitably insulated from grounded surface and
limited in length to 10 feet or less.
• Open voltage: 12 Vdc
• Peak current: 1 mA
