Product catalog summary

MK20/2 Series Reed Sensors Overview
The MK20/2 Series Reed Sensors are cylindrical sensors with options for cable termination and lengths, available in various case sizes. They are suitable for applications such as door and window contacts, water level detection with magnetic floats, and position sensing. These sensors are used in markets including appliances, industrial, and security.

Specifications

Contact Data: Rated power is 3 W, with a maximum switching voltage of 30 V and a maximum switching current of 0.3 A. The carry current is 0.5 A, and contact resistance is 200 mOhm.
Breakdown Voltage: Minimum of 0.1 kVDC according to EN60255-5.
Operating and Release Time: Maximum operating time is 0.25 ms, and release time is 0.15 ms.
Insulation Resistance: Typically 10¹⁰ Ohm.
Capacitance: 0.1 pF at 10kHz across an open switch.

Housing and Lead Specifications

Material: Housing is made of PBT 30% GF, with a black case color and polyurethane sealing compound.
Cable: Single wires made of PVC with a cross-section of 2 x 0.06 mm².

Environmental Data

Shock Resistance: Maximum of 50 g.
Vibration Resistance: Maximum of 20 g.
Operating Temperature: -30 to 70 °C when the cable is not moved, and -5 to 70 °C when moved.
Storage Temperature: -30 to 70 °C.

Handling & Assembly Instructions

Maximum torque for screws is 1Nm.
Cable bending-radius should be diameter x 15, with a minimum bending distance to housing of 5mm.
Avoid using magnetically inductive screws and ensure no drag marks out of the mounting area.
For cable lengths over 5m, a series resistor is recommended.

Glossary

Contact Form: Form A (Normally Open), Form B (Normally Closed), and Form C (Changeover).
Magnetic Sensitivity: Sensitivity levels B, C, D, E with AT ranges of 10-15, 15-20, 20-25, and 25-30 respectively.

Note: Technical specifications are subject to change for technical progress. For the most current specifications, contact the nearest sales office.
