Airtac DS1B Electronic Sensor DS1B7020
The AirTAC Airtac DS1B Electronic Sensor DS1B7020 is a genuine DS1 contactless solid-state magnetic switch (normally open) that senses the piston magnet in a pneumatic cylinder. It is the 2-wire version, supplied with a 2 m cable. The B7 type fits SI200. A red LED shows output; the housing is rated IP67.

About the Airtac DS1B Electronic Sensor DS1B7020
The AirTAC DS1B7020 is a contactless solid-state magnetic switch, normally open, for the large SI200 cylinder. It is the 2-wire form on 10-28 V DC at up to 50 mA, wiring in series with the load like a reed but with no moving contact, so it switches fast and lasts. A red LED shows output on the 2 m cable.
The B7 type clips straight onto the SI200 body with no accessory and, like all B-types, adds output short-circuit protection on top of the reverse-polarity and surge protection. It is IP67 rated over a -10 to 70 C range. Exact fit is confirmed from the datasheet.

How to choose
The 2-wire form is the simplest wiring for a PLC input, but it leaks up to 90 uA and drops about 2.65 V; for a very high-impedance input or 5 V logic, step up to the 3-wire NPN or PNP form (0.01 mA leakage, 0.5 V drop, 200 mA). Choose the solid-state DS1 over the reed CS1 for fast, high-cycle duty.
At 24 V the 2.65 V drop is about 11 percent, which most inputs tolerate. Keep the load under 50 mA on the 2-wire form.
Applications
SI200 stroke-end confirm
Confirms the large SI200 cylinder has reached its stroke end before unclamping.
Heavy-press position
Signals ram position on a heavy SI200-driven press station.
2-wire PLC input
Feeds a 24 V PLC input with the simplest two-wire series connection.
FAQ
What protection does the B7 add?
Like all DS1 B-types it adds output short-circuit protection on top of reverse-polarity and surge protection. It is the 2-wire 10-28 V form.
When should I choose 3-wire instead?
For a very high-impedance input or 5 V logic: the 3-wire form leaks only 0.01 mA and drops 0.5 V, versus the 2-wire's 90 uA leakage and 2.65 V drop.
