Characteristics

Non-contact end switches of the BTP series are designed for switching
control circuits by means of a relay or through matching blocks of contactless
logical elements. Switches change the switching state
(triggered) when approaching the sensitive element of the control element
from structural steel.

Peculiarities:

• Switch Operation
• BTP-101 - short circuit
• Maximum exposure distance - 7mm
• Type of control element - structural steel plate (or controlled part)
• Degree of protection - IP67

General information

Switches are designed for switching control circuits by means of relays or through matching elements of non-contact logic elements. The switches change the switching state (trigger) when approaching the sensing element of the control element made of structural steel.

The switches work on the principle of a controlled generator, switching occurs when approaching the sensitive element of the controlled part or the control element made of structural steel.
Switches BTP 101-24, BTP 102-24, BTP 103-24, BTP 104-24, BTP 211-24 and BTP 301-24 are made on a discrete element base. The supply voltage of the generator and the trigger of these switches is stabilized by a parametric stabilizer.
Switches BTP 212-24, BTP 213-24 and BTP 421-24 are made on an integrated element base.
All switches are equipped with circuits for protection against reverse polarity of the supply voltage and against overvoltages when disconnecting an inductive load.
Switches BTP 103-24, BTP 211-24-01 and BTP 301-24, in addition to the above protection circuits, are equipped with a protection circuit against overloads and short circuits in the load circuit.
