Sensor box SB1S
0.5 4.5Volt signal output and two Open-Collector control outputs
Special features SB1S
The SB1S sensor box is a pressure-cast aluminum box ( IP65) with integrated sensor for single axis Inclination or for Acceleration measurement.
The SB1S 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.
The SB1S has also two Open-Collector outputs, The trigger point for thresholds can be individually adjusted by means of two trim-potentiometers, this within the whole working range of the actual sensor. Optional can these also be supplied as 1: Normal open 2: Normal closed.
In the SB1S box can the NG type sensor 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 SB1S is used everywhere, where inclination or acceleration measurements are wanted together with a high level 5DC voltage output + the possibility to have 2 switching outputs for controlling and safety purpose. In particular in cranes, buildings, mining industry, radar systems, bridges, ships, in agricultural machinery and in all types of process machinery, just name it ! SB1S can be for very good use everywhere.

Dimensions and connections
The Open-Collector outputs are protected with diodes for spikes on the supply, while switching inductive burdens
CAUTION ! Do not short-circuit the operating voltage (8 to 30V) with one of the outputs !
The OC outputs can as option function like: "HIGH = going high when the limit are excited" = Version L (LOAD ) or " LOW = going LOW when the limit are excited " = Version N ( NUTURAL).
The version L offers the possibility to connect both OC outputs (wired OR) as only one control signal (e.g. honk) to be activated, during passing the one or the other limit.
The N version do give the possibility of higher safety of alarms since an open-line condition and operating power failure will cause an overriding of the limiting value and then cause an ALARM output
