The 7000-IO series consists of a self-contained transmitter SMT, and a receiver SMR, which are to be used in thru-beam mode, an SMP for diffuse proximity, SMRR for retro reflective and an SMPF for use with fibre optic cables.

The complete series is available with a 10-30 V dc supply voltage and with an NPN or PNP transistor output that can be connected as a push-pull configuration or as a supplementary output.

The SM 7000-IO is equipped with an IO-link communication interface which allows a variety of process parameters and settings to be configured and monitored, which includes: sensitivity adjustment, teach-in function, automatic gain adjustment, output mode, on/off time delay, one-shot timer, hysteresis. Sensitivity adjustment and light or dark function may also be manually configured via integral potentiometers.

The SMR is available with either a 0.5 ms response time and a 7 metre range or with a 2 ms response time and a 20 metre range. The test input in the SMT is intended to be used for disabling or enabling the transmitting power temporarily for test purpose or for multiplexing applications.
