AI-TEK Hall Effect Speed Sensors [Click here For Details]

The AI-TEK Hall Effect magnetic speed sensor can detect each change in target movement, regardless of speed, from near zero to 15 kHz frequency range, generating a steady pulse train of frequency proportional to target speed.  Key features of this AI-TEK product include

AI-TEK Hall Effect Speed Sensors

Reverse voltage protection
Higher temperature range of -40C to +125C
Wide range of supply voltage 4.5 - 24 VDC
Two output options - supply tracking or TTL
Rugged design meeting IEC 77 standards
