THE ALL IN ONE PROXIMITY SENSOR AND LIMIT SWITCH. GO … · 70 Series GO Switches outperform inductive proximity switches in the toughest applications. End sensing range can be extended

THE ALL IN ONE PROXIMITY SENSOR AND LIMIT SWITCH.GO Gets It.

GO Switch is the most versatile sensing solution. It detects like a proximity switch and functions like a limit switch, providing higher reliability when conventional switches fail.

TM

GO Switch models 11, 21, 31 and 81 are the ideal replacements for traditional mechanical limit switches. Sealed contacts, rugged housings,non-contact detection of ferrous metal & magnetic targets, and snap action response make these switches the ultimate problem solvers for troublesome mechanical limit switch applications.

GO™ SWITCH - EXTENDED SENSING

W W W. T O P W O R X . C O M 6

MODEL 11

Sealed contact chamber prevents moisture or dustfrom reaching the contacts.

Versatile gold fl ashed contacts are suitable for high and low electrical loads, and can be wired AC or DC, N/O or N/C.

Seesaw armature provides snap actionand solid contact pressure, eliminating ‘contact teasing’ and ‘contact chatter’

in high vibration applications.

Rugged brass or stainless steel housing withstands physical

abuse, moisture, and corrosives.

Multiple wiring options: - Terminal Block - Lead Wires - Subsea - Cable - Quick Disconnects

Conduit hub can be located in any of 5 positions for versatileinstallation.

Potting fi lls the entire switch cavity, forming a barrier against moisture.

Consumes no power to operate and has no current leakage or voltage drop.

Side sensing range can be extended to nearly 4" using

external target magnets.

Models 11, 21, 31, and 81 were the world's original GO™ Switches. Their simple design, rugged housings, long sensing ranges, and global approvals make these switches the ideal choice wherever reliable proximity sensing is needed. Some features common to all these models include a standard operating temperature range of -58°F to 221°F (-50°C to 105°C) and gold-plated SPDT dry contacts.

With all stainless steel construction, fl exible AC/DC, NO/NC, and SPDT/DPDT contact confi gurations, superior corrosion resistance, and global certifi cations for all hazardous areas, 70 Series GO Switches outperform inductive proximity switches in the toughest applications.

End sensing range can be extended using external target magnets.

Three magnets provide snap action and solid contact pressure, eliminating ‘contact teasing’ and ‘contact chatter’ in high vibration applications.

Sensing face is stainless steel rather than plastic, preventing damage due to incidental physical contact.

English or metric threads available.

Permanent magnets

One-piece stainless steel construction makes this a very

durable proximity sensor.

Sealed contact chamber prevents moisture or dust from reaching the contacts.

Consumes no power to operate and has no current leakage or voltage drop.

Multiple wiring options:-Lead Wires-Cable-Subsea-Quick Disconnects

Unique sawtooth contacts are suitable for high and low electrical loads, and can be wired AC or DC, N/O or N/C.

Potting fi lls the entire switch cavity, forming a barrier against moisture.
