Now also available in Stainless Steel Housing 


Special features


The SB1U sensor box is a pressure-cast aluminum box ( IP65) with integrated sensor for single axis Inclination or for Acceleration measurement.

The SB1U contains an amplifier part with 0…5VDC output signal possibility, also as a separate part on the board there is a high-stable power supply for supplying the actual sensor ( this can also be taken out as an ref. Voltage ! ). The amplifier for the Signal output, contains also a low-pass filter for upper frequencies limitation. Rise-time constant as a specific value, + an max. current output limitation, can also be a part of the custom built unit. Supply noise suppression filter and diode bridge for guarantee of the Electromagnetic Compatibility are also a standard part in this unit. Sensor and amplifier are galvanic isolated from the housing.

In the SB1U box the NG type or the NB3 sensor can also be implemented, which means a very high degree of a accuracy on the measuring of inclination and an considerably reduced temperature drift over the whole temperature range, this as the highest degree of accuracy of all SEIKA products.

A strong metal PG cable gland and the solid and compact housing for the whole Sensor box in connection with the high voltage signal output gives al together a high-quality system for use under many types of difficult working conditions.


The SB1U is used everywhere, where inclination or acceleration measurements are wanted together with a high level DC voltage output. In particular in buildings, mining industry, radar systems, bridges, ships, in agricultural machinery and in all types of process machinery, just name ! and SB1U can be for very good use everywhere.

Dimensions and pin assignments

Caution ! The supply voltage (8 to 30V) must NOT be wrong connected to any output signal.
