It detects like a proximity switch and functions like a limit

1 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

2 GO SWITCH - EXTENDED SENSING 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. Seesaw armature provides snap action and solid contact pressure, eliminating contact teasing and contact chatter in high vibration applications. 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. Side sensing range can be extended to nearly 4" using external target magnets. Sealed contact chamber prevents moisture or dust from reaching the contacts. Permanent magnets Potting fi lls the entire switch cavity, forming a barrier against moisture. Rugged brass or stainless steel housing withstands physical abuse, moisture, and corrosives. Multiple wiring options: - Terminal Block - Lead Wires - Subsea - Cable - Quick Disconnects MODEL 11 Conduit hub can be located in any of 5 positions for versatile installation. Consumes no power to operate and has no current leakage or voltage drop. 6 W W W. T O P W O R X. C O M

Some features common to all these models include a standard range of -58 F to 221 F (-50 C to 105 C) and gold-plated SPDT dry contacts.

3 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 range of -58 F to 221 F (-50 C to 105 C) and gold-plated SPDT dry contacts.
