What type of sensing technology does this device use?
It is an inductive proximity sensor designed to detect metallic targets without physical contact. It is built in an M12 (12 mm) cylindrical, threaded housing.
What is the nominal sensing distance and the assured operating distance?
The nominal sensing distance (Sn) is 4 mm, and the assured sensing distance (Sa) is 3.24 mm for reliable switching under specified conditions.
Is it suitable for flush (embedded) mounting in metal?
Yes. This model is intended for flush (embedded) installation in metal, helping maintain a compact mounting profile.
What output type does it provide?
It provides a PNP switching output with a normally open (NO) switching function (switching contact).
What supply voltage does it require?
It operates on 10–30 V DC with a 3-wire DC electrical design.
What is the connector style and standard pin assignment?
It uses an M12, 4-pin connector. Typical pin assignment: Pin 1 (BN) = L+ (positive supply), Pin 3 (BU) = M (0 V), Pin 4 (BK) = switching output (Q), Pin 2 = not connected.
What is the maximum load current the output can switch?
The continuous output current (Ia) is up to 200 mA. The sensor’s voltage drop is specified as up to 2 V at maximum load.
How fast can it switch (switching frequency)?
The switching frequency is up to 2,000 Hz, making it suitable for fast detection tasks.
Does it support IO-Link communication?
Yes. It supports IO-Link V1.0 (COM2, 38.4 kBaud). Process data length is 1 byte; the process data structure includes status bits such as Bit 0 = Sr reached and Bit 1 = Sa reached.
What environmental protection rating does it have?
It is rated IP68 and IP69K, supporting use in harsh industrial environments. The housing is stainless steel (V2A / AISI 303).
What is the operating ambient temperature range?
The operating ambient temperature range is −40 °C to +100 °C.
How do different target materials affect sensing distance?
Sensing distance varies by metal type. As guidance, the reduction factor is 1.0 for steel (St37/Fe). For stainless steel (V2A) it is approximately 0.65, and for aluminum (Al) approximately 0.35, meaning the effective sensing distance is reduced compared with mild steel.
What are the key mechanical dimensions and mounting considerations?
It has an M12 x 1 thread, 65 mm overall housing length, and 48 mm usable thread length. Typical recommended tightening torque is about 20 Nm (using the non-serrated side of the nut) or about 32 Nm (using the serrated side). The IMB12-04BPSVC0S is supplied with two stainless steel mounting nuts with locking serration.
