Lingenfelter RPM-003 Digital RPM Window Switches

Lingenfelter RPM-003 digital rpm window switches provide microsecond precision! These switches from Lingenfelter Performance Engineering are capable of performing as standard rpm-activated switches or they can provide "window" switch-type capability, switching when one rpm level is reached and then switching back when a second rpm set point is reached. The digital rpm window switches utilize a precision 32-bit timer to realize microsecond precision over a very wide operating rpm range, and they support most common tachometer pulse frequencies, without additional components being required. Lingenfelter RPM-003 digital rpm window switches also feature: * Two-color LED for error codes and operating condition notification * Custom-molded, high-temperature, glass-filled Nylon 6 enclosure * A tachometer pull-up resistor enabled by a dip switch setting inside the back cover * An analog 0-5 V input signal that can provide TPS, clutch sensor, or MAP sensor input Show Less
