HIMA Z7108/3237/C7/R2 Special Cable Plug

FAQ

Q1: What is HIMA Z7108/3237/C7/R2?
A: It is a special cable plug for the HIMA F 3237 safety-related input module, configured for redundant NAMUR proximity-switch applications.

Q2: Which module is it compatible with?
A: It is specifically designed for the HIMA F 3237 8-channel safety input module.

Q3: What is the R2 configuration used for?
A: R2 is used as part of the special redundant connection arrangement for NAMUR proximity switches. HIMA specifies the R2 plug together with the corresponding R1 configuration.

Q4: What resistors are used in the NAMUR configuration?
A: The special NAMUR arrangement uses 390 Ω resistors for R1–R8.

Q5: What is the HIMA order number?
A: The documented order number for the Z7108/3237/Cx/R2/S209 configuration is 93 3237 209.

Q6: What type of sensors can be connected?
A: It is intended for NAMUR proximity switches according to EN 60947-5-6.

Q7: What are the dimensions and weight?
A: The connector is approximately 120 × 40 × 25 mm (L × W × H), with an estimated weight of approximately 0.15 kg. These mechanical values should be treated as reference values because the HIMA F 3237 documentation does not provide a separate dimensional specification for every Z7108 cable-plug variant.

Q8: Can it be used as a standalone module?
A: No. It is a cable-plug accessory and must be used with the compatible F 3237 input module and the appropriate NAMUR/redundant wiring configuration. HIMA also notes that using the special cable plug in the safety loop can affect the achievable SIL level depending on the connected proximity switch.
