The limit switch of the 3SE5 series features a compact design and a metal housing, making it ideal for use in harsh environments or on devices with limited space. The 3SE5 413 switch meets EU standards and has a 30 mm wide housing with mounting holes spaced 20 mm apart; the 3SE5 423 switch meets US market requirements and has a 40 mm wide housing with mounting holes spaced 25 mm apart. Both types of the 3SE5 limit switch have a depth of only 16 mm and a weight of 80 g (without cable).

The metal housing and the rotary actuator element have an IP67 protection rating. There is 1 normally closed and 1 normally open snap contact (the normally open contact meets the requirements for positive opening according to IEC 60947-5-1). The switch is suitable for use in safety circuits up to category 4 according to EN ISO 13849-1. Connection is made with a molded cable of 2 m or 5 m or via an M12 socket. The actuating elements can be rotated in 90° increments. Time can be saved by mounting the fully pre-assembled unit. The switch is resistant to electromagnetic interference.
