GO™ Switchc Extended Sensing

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. Additional options include: • Extend sensing distance up to 98mm using target magnets • Double Pole Double Throw (DPDT) • Latching Contacts • Current rating up to 10A/ 120VAC • Wide variety wiring options such as lead wires, cables, quick disconnects (Micro or Mini) and terminal block design.
